At DAE Pumps, we have a complete range of high-quality submersible slurry pumps made for dewatering and dredging the most abrasive media, like sand, with high solid content in quarries and mining operations. The user-friendly design and easy-to-use submersible sand and slurry pumps are why they are the preferred choice for submersible pumps.

Submersible slurry pumps and submersible sand pumps offer the highest in quality and strength over other submersible pumps. They are capable of moving large amounts of sand and slurry with ease and without clogging. DAE Pumps submersible sand and slurry pumps withstand the abrasive material that passes through them on a consistent basis and provide the power to move the material. The following is to help understand pump specifications for selecting the right submersible slurry pump or sand pump for you. A DAE Pumps representative is also available.

The size of the submersible pump is important when connecting the discharge end. The hose or pipe that connects to the pump should match the discharge or the pump. If fitting an adjustment to the end of the submersible slurry pump, the fitting can only work when goes downward in size, not upward. Typically, the pump size limits the gallons per minute a submersible slurry pump is capable of pumping. The larger the pump size, the more allowable volume, and solids sizes.

The power of the electrical submersible slurry pump is determined by the motor size in horsepower. The more horsepower, the more material it can move (volume), and the higher the head of which it can pump. When moving sand and slurry, it is important to take horsepower into consideration. As sand and slurries can be heavy, this causes friction that slows down the movement of the material. If there is too much friction and the submersible sand pump is not powerful enough to push the sand or slurry, the material will start to settle in the hose or piping, and not deliver to the final destination.

When selecting a submersible slurry or sand pump be sure to understand the volume of the material you are looking to move. Submersible pump specifications are typically based on pumping water. When pumping sand, slurry, and other solids, DAE Pumps industrial slurry pumps move between 15% to 30% solids.  Therefore, the remaining 70% to 85% is water.  While a 100 GPM sand pump can process about 15% material, thus 15 GPM of sand, a 100 GPM slurry pump can process about 30% material, thus 30 GPM of slurry. This all varies depending on how aggressive the operator is with the pump. Ensuring the correct power of a sand pump is essential for delivering sand the distance needed because sand is heavy and settles. Not enough power will leave sand in the hose and backup. Knowing the liquid viscosity is important for ensuring proper pumping. Ask DAE Pumps for assistance with a viscosity test to ensure accurate pump selection.

In addition to the amount of material you pump, you want to make sure there is a consistent inflow of water or fluid replacing liquid and material that is being pumped out for the proper operation. Lack of fluid is never good for submersible pumps.

Here are a couple of equations and examples to help figure out how much material a submersible slurry pump can move and approximately how long it will take to move your material.

The head is the height at which the pump can raise water. The weight of a gallon of water at room temperature is 8.33 lbs. If all that is being pumped is room temperature water, the height a submersible slurry pump could pump that water is the max head stated on the pump specifications. However, submersible slurry pumps and submersible sand pumps are pumping more than just room-temperature water. They are pumping sand, silt, rocks, mud, debris, and other types of slurries. These slurries have a different weight that is more than the weight of water. Thus, the head of a pump that is pumping slurries and sand is going to be less than the stated head on a pump.

The size of solids is that can pass through a submersible slurry pump are typically determined by the allowable area between the pump’s impeller and the volute. Submersible pumps are designed with more or less separation for the type of material they are intended to handle. Those with more separation are submersible slurry pumps because they can process larger materials. The submersible pump with less separation is a drainage pump that does not move many solids.

The motor or engine on a pump is as important as the pump itself. It is the driving force that makes the pump go. DAE Pumps offer a variety of motor choices: electric, diesel, and hydraulic.

Frames and skids hold the pump and motor together to make a complete unit. The frame provides stability for the placement of the pump and motor with the intent of a permanent install or seldom movement. The DAE Pumps trailer brings mobility to centrifugal slurry pumps. The whole unit, skid included, is mounted onto a trailer for mobile accessibility. Many industries use centrifugal pumps for performing multiple applications, and they move from one location to another quite frequently. The trailer provides a tremendous advantage of being on wheels.

Centrifugal pumps come in many shapes and sizes. There are two main parts to a centrifugal pump; the pump and the motor/engine. The electric motor or a diesel engine converts the energy it creates into mechanical energy. This mechanical energy drives the pump and moves the water. The centrifugal slurry pumps pull water and other materials in through the inlet and pushes it out through the outlet/discharge.

The electric motor and diesel engine work relatively similarly. A motor consists of a fan and protective casing mounted at the back. Inside the motor is the stator. The stator holds copper coils. Concentric to this is the rotor and shaft. The rotor rotates, and as it spins, so does the pump shaft. The shaft runs the entire length of the motor and into the pump where it connects to the pump’s impeller.

There are a couple of variations to a centrifugal pump. Some models of centrifugal pumps have a separate shaft for the pump and the motor. The connection between the separated shafts is called the coupling. These coupled pumps will contain a bearing house with bearings. The pump shaft then continues into the pump casing. As it enters the casing it passes through a gland, packing, and the stuffing box, which combined to form a seal. The shaft then connects to the impeller. The impeller imparts centrifugal force onto the fluid that makes it to move liquids through a pipe or hose. The impeller is in the pump casing. The casing contains and directs the flow of water as the impeller pulls it in through the suction inlet and pushes it out through the discharge outlet.

At the pump casing, there is a channel for water to flow along, which is called the volute. The volute spirals around the perimeter of the pump casing to the outlet. This channel increases in diameter as it makes its way to the outlet. The shaft passes through the seals and into the pump casing, where it connects to the impeller.

Liquid engulfs the impeller, and when it rotates, the fluid within the impeller also spins and is forced outward to the volute. As the fluid moves outwards, off of the impeller, it creates a region of low pressure that pulls more water in through the suction inlet.  The fluids enter the eye of the impeller and are trapped there between the blades. As the impeller rotates, it imparts kinetic energy or velocity onto the liquid. By the time the liquid reaches the edge of the impeller, it is moving at a very high speed. This high-speed liquid flows into the volute where it hits the wall of a pump casing. This impact converts the velocity into potential energy or pressure. More fluid follows behind this developing a flow.

The thickness of the impeller and the rotational speed affects the volume flow rate of the pump and the diameter of the impeller, and the rotational speed increases the pressure it can produce.

Net Positive Suction Pressure or NPSH is associated with pump suction. At the end of this acronym are two other letters NPSHR and NPSHA. The R is the required NPSH. Each pump tests for this value. At DAE Pumps, we provide a pump operation chart with all our specs. The R-value is a warning or danger point. As the fluid enters the pump and flows into the impeller’s eye, it experiences a lot of energy due to the friction, giving a pressure drop. At certain conditions, the fluids flowing through this section can reach a boiling point. Once this happens, cavitation may occur.

The last letter in NPSHA stands for Available. The net positive suction pressure available depends on the installation of the pump and should be calculated. NPSHA takes into consideration things like insulation types, elevation, liquid temperature, liquid boiling point, much more. Available pressure should always be higher than the required value. For example, if the NPSHA is 12 for the pump requiring an NPSHR of 4 then the pump should be okay. However, a pump that required an NPSHR of 15 than the available NPSH is insufficient, and cavitation will occur.

DAE Pumps provides custom pump curves per the information you provide. Including as much information about the project allow us to best match a pump with your needs, so the centrifugal pump you get is ideal for the project.

Cavitation in pumps is the deterioration of the pump’s metal due to the overheating of water. Cavitation destroys the pump’s impeller and casing that lead to replacing parts and the pump altogether.

Water can turn from a liquid state into steam or gas and boils at around 100 degrees Celsius at sea level. However, at a higher elevation, water boils at a lower temperature because of atmospheric pressure. If this pressure is less than the vapor pressure of the liquid that is pumping, then the water can reach a boiling point. When this happens, cavitation occurs.

During cavitation, air particles within the water expand, and as they reach the boiling point, they collapse in on themselves very rapidly. As they collapse, they start to damage the impeller and pump casing. This damage removes small parts of metal from the surface, and if this keeps occurring, then it will eventually destroy the pump. Therefore, you must ensure the Available pressure is higher than the Required pressure of the pump.

Slurry is one of the most challenging fluids to move. It"s highly abrasive, thick, sometimes corrosive, and contains a high concentration of solids. No doubt about it, slurry is tough on pumps. But selecting the right centrifugal pump for these abrasive applications can make all the difference in the long-term performance.

Slurry is any mixture of fluid and fine solid particles. Examples of slurries would include: manure, cement, starch, or coal suspended in water. Slurries are used as a convenient way to handle solids in mining, steel processing, foundries, power generation, and most recently, the Frac Sand mining industry.

Slurries generally behave the same way as thick, viscous fluids, flowing under gravity, but also pumped as needed. Slurries are divided into two general categories: non-settling or settling.

Non-settling slurries consist of very fine particles, which give the illusion of increased apparent viscosity. These slurries usually have low wearing properties, but do require very careful consideration when selecting the right pump because they do not behave in the same manner as a normal liquid does.

Settling slurries are formed by coarse particles that tend to form an unstable mixture. Particular attention should be given to flow and power calculations when selecting a pump. The majority of slurry applications are made up of coarse particles and because of this, have higher wear properties.

Many types of pumps are used for pumping slurries, but the most common slurry pump is the centrifugal pump. The centrifugal slurry pump uses the centrifugal force generated by a rotating impeller to impact kinetic energy to the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.

Slurry applications greatly reduce the expected wear life of pumping components. It’s critical that pumps designed for these heavy-duty applications are selected from the start. Consider the following when making selections:

To ensure the pump will hold up against abrasive wear, the impeller size/design, material of construction, and discharge configurations must be properly selected.

Open impellers are the most common on slurry pumps because they’re the least likely to clog. Closed impellers on the other hand are the most likely to clog and the most difficult to clean if they clog.

Slurry pumps are generally larger in size when compared to low-viscosity liquid pumps and usually require more horsepower to operate because they"re less efficient. Bearings and shafts must be more rugged and rigid as well.

To protect the pump’s casing from abrasion, slurry pumps are oftentimes lined with metal or rubber. Goulds Pumps, for example, lines their XHD (Extra Heavy Duty) slurry pump with rubber.

The casings are selected to suit the needs of the application. For instance, pumps used in cement production handle fine particles at low pressures. Therefore, a light construction casing is acceptable. If the pump is handling rocks, the pump casing and impeller will need a thicker and stronger casing.

Those with experience pumping slurries know it"s not an easy task. Slurries are heavy and difficult to pump. They cause excessive wear on pumps, their components, and are known to clog suction and discharge lines if not moving fast enough.

It’s a challenge to make slurry centrifugal pumps last for a reasonable amount of time. But, there are a few things you can do to extend the life of your slurry pump and make pumping slurry less of a challenge.

Find the sweet spot that allows the pump to run as slow as possible (to reduce wear), but fast enough to keep solids from settling and clogging the lines

Pumping slurries poses several challenges and problems, but with proper engineering and equipment selection, you can experience many years of worry-free operation. It"s important to work with a qualified engineer when selecting a slurry pump because slurries can wreak havoc on a pump if not properly selected.

Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 75 tonnes of ore per hour, and at 65% solids, every time a hose pump replaces a process slurry pump, it saves over 1,100 Million litres of water annually because of the slurry pump’s inefficiency : on the same duty, the hose pump requires less than 25% of the process water of a slurry pump.

On the same 75 ore tonnes per hour plant, on thickener underflow duty at full flow, a VF125 hose pump absorbs around 35 kW whereas a slurry pump needs over 70kW : a saving of over 50%. This directly translates into reduced electrical requirements. Power rationing is a concern for many established mines, on new developments the infrastructure costs to import power can be considerable and can even cause significant delays and generate considerable non-mining environmental opposition.

Many mineral recovery processes use Cyanide based leaching techniques especially where Gold is a key mineral. Cyanide has many adverse environmental consequences including polluting the land surrounding the plant, contaminating aquifers and decimating life in water courses. The traditional dosing solution, progressing cavity pumps have integral seals requiring regular replacement and representing a clear leakage risk. Peristaltic pumps are seal-less and consequently, have a much lower contamination risk.

The peristaltic pump has a very gentle pumping action that minimises damage to fragile cell cultures in bio-oxidation reaction techniques. One such requirement , the Biox (R) process that uses a live culture to free gold from sulphide ores, reducing Cyanide usage and improving process yields.

A peristaltic pump’s gentle low shear pumping action maintains particle size minimising the use of flocculent and other process reagents. Conventional high shear technologies such as progressive cavity or screw pump significantly increase reagent usage increasing operating costs and raising post processing costs due to flotation reagent carryover. Similarly, residual reagent can increase the waste remediation cost or increase the environmental damage from tailings dams or their resultant groundwater pollution.

Slurries are often acidic and or highly abrasive. Consequentially, conventional slurry pumps use impellers made from increasingly expensive and non standard materials with service lives that are measured in days.

In contrast, on a peristaltic pump, only the rubber hose is in contact with the pumped liquid and as the ultimate rubber lined pump, service life is measured in months, reducing pump downtime and as the hose can easily be changed in situ, maintenance hours are similarly reduced.

To pump highly acidic slurries, hoses are made from several standard elastomers, each proven in the mining environment to withstand process chemicals and avoiding the use of expensive exotic metal impellers.

Finishing parts with certain types of media can generate a slurry mixture consisting of worn down pieces of media and the imperfections of your parts. Having an area where you can rinse off parts quickly can speed up your operation and make your workers much happier. Multiple shelving levels gives the operators space to set things like chemical cleaners, towels and tools. MFI also offers optional media pans and screens.

The Sludge Pump is a great tool for cleaning up water and slurries. Simply attach the pressure line from a portable power washer or car wash bay. The water flowing through the high pressure nozzle creates a powerful venturi suction that vacuums up slurry solutions. Debris as large as 3/4" will pass through the casting and out the discharge hose.

Sludge, slurry and sewage—three topics that aren’t a subject of everyday “pleasant” conversations. Any of these words conjures images of yucky goo, germs, and debris. But dealing with these fluids is a fact of life, and you need the right kind ofsubmersible pumpto handle the heavier load.

Having the right pump helps considerably with handling sludge and slurry safely. But with many brands and types of pump on the market, what kind of heavy-duty pump do you need to handle the workload?

Sludge pumps and slurry pumps are often considered interchangeable, but they do have slightly different functions. Both sludge and slurry are fluids with a high percentage of solids, but sludge is softer and thicker. Slurry is thinner and flows through the pipes more easily.

This article explains everything you need to know about sludge and slurry pumps, including the difference between a sludge pump and a slurry pump, and when you might need one.

Sludge has a thick texture that may be very viscous or sticky, making it difficult to pump. However, with a higher percentage of solids, it is more compact and can facilitate the disposal of waste products.

Slurry is a water-based mixture that contains solids in suspension. It’s commonly generated in industrial, mining and agricultural settings. Slurry is thin and sloppy, and flows more easily than sludge.

Being easier to pump, slurry is the preferred output where waste needs to be transported in liquid form. Being distributed in a liquid suspension, slurries can make it easier to relocate and dispose of waste products in the mining and construction industries.

Both sludge and slurry are mixtures of liquid and pulverised solid waste, but they are not the same. Sludge has a heavier consistency, like thick mud, while slurry is thinner and less viscous.

The main difference between sludge and slurry is the texture, rather than the composition of the fluid. Both slurry and sludge contain solids such as sand, mud, metals, sediments, and other particles within the liquid. They may be organic (like sewage) or non-organic.

Sludge is a thick and viscous fluid, and may be sticky, while slurry is thinner and flows more easily. This means that pumping requirements can vary significantly between these two fluids, and is also influenced by the type of particles found in the material.

Both sludge and slurry are often industrial byproducts, meaning that liquid might also contain certain acids, alcohols, oils, or other solvents. Therefore, both sludge and slurry need to be correctly and responsibly disposed of, considering the environmental impact and local regulations.

The purpose of the sludge pump is to move sludge through sewer lines or other systems. Sludge can be heavy and often abrasive and corrosive; therefore, these pumps need to be high-powered. The heavier the sludge, the more horsepower that is required.

Centrifugal pumpsare commonly used thanks to their ability to pump effluent reliably. A centrifugal pump consists of a rotating impeller that converts electrical energy from the motor into kinetic energy. The kinetic energy is then converted to pressure, which creates the flow of the sludge through the pump.

These pumps can handle particles up to the size of sand, and flow rates can go as high as thousands of litres per second. However, these pumps cannot generate pressures higher than 1000 psi.

Positive displacement pumps work differently. While centrifugal pumps use continuous energy to increase the sludge flow, positive displacement pumps work by intermittently adding energy to increase pressure. They can generate more pressure than centrifugal pumps, but their flow rate can only go up to nine hundred and fifty litres per second.

There are two designs for the positive displacement pumps: either reciprocating (such as the plunger and piston design) or rotary (progressing-cavity pumps and rotary vane vacuum pumps being examples).

Slurry pumps are the type of pumps that are appropriate for pumping slurry. Choosing the suitable pump will depend on the size and types of solids in the slurry liquid and how corrosive the slurry mixture is. The larger and more corrosive the slurry is, the more heavy-duty the pumps would need to be.

Centrifugal pumpsare mainly used for slurry at concentrations less than seventy percent solid by weight; and come in various appearances, such as horizontal, submersible, and vertical.

Positive displacement slurry pumps are more limited when it comes to capacity, but they are better for pumping slurry with higher concentrations of solid material.

Centrifugal pumps, such asBianco Vulcan centrifugal pumpare above ground pumps that can be added to existing pump lines to add more power and suction force to the set up. In comparison,submersible drainage pumpssuch as theNova submersible pumpare powerful pumps ideal for removing water from an area, either on a daily basis or in case of emergencies.

Positive displacement slurry pumps are more limited when it comes to capacity, but they are better for pumping slurry with higher concentrations of solid material.

Water pumps differ from slurry or sludge pumps. The viscosity and composition of these fluids mean they need much higher pressure and hydraulic capacity than water pumps. Finally, water pumps cannot withstand potential chemical corrosion and particle abrasion.

Sludge and slurry both contain solid particles, including (but not limited to) sand, gravel, and metals; the difference lies in their consistency. Furthermore, while the liquid in sludge and slurry can indeed be water, it can also contain other types of liquid such as petroleum and various acids.Due to the difference in viscosity and composition of slurry and sludge, installing and using the correct type of pump is imperative.For pumping slurries, a centrifugal pump or heavy-duty drainage pump is used.For pumping sludges, positive displacement pumps such as diaphragm pumps, lobe pumps, and Moyno pumps are best.

A sludge or slurry pump can be used to pump out sewage from sewage lines. The most common type of pumps used for sewage are centrifugal pumps. These pumps can effectively push sewage and can be installed in pits and sumps.

Due to their higher starting costs and complex maintenance, reciprocating pumps are less common than centrifugal pumps. Reciprocating pumps are used in specialised cases when a larger-than-normal quantity of sewage needs to be pumped.

If you are dealing with a small amount of sewage that doesn’t justify the need to construct a pumping station, you can use air pressure pumps or pneumatic ejectors. Unlike other pumps with spinning impellers or pistons, these pumps use compressed air to move sewage. These small-capacity pumps are quieter, have fewer moving parts, and develop blockages less frequently. However, they are the least efficient among the pumping options available.

Because there are several conditions where a slurry pump or a sludge pump is called for, there are three types of installations to consider: dry installation, semi-dry installation or wet installation, which involves fully submerging the pump.

First is a dry installation where the bearings and the pump drive are kept out of the sludge or slurry. The wet end—which may include the impeller, suction liner, shaft sleeve, and shell—is free-standing and out of the way of any liquid. Horizontal slurry pumps are mostly dry installations.

The second method is semi-dry installation. The operator floods the wet end and the bearings but keeps the drive dry. This installation is often used for dredging with horizontal pumps.

The final method is wet installation. Using this method, the slurry pump and drive are fully submerged. Wet installation is often reserved for underwater operations, cement plants, dyeing and printing plants, and similar industries. The pumps used are oftenvertical centrifugal pumpswith semi-open impellers.

A pump is cavitating when the liquid in the pump turns to vapour at low pressure. Cavitation happens when voids (or bubbles) form within the slurry because the pressure rapidly decreases below the vapour pressure.

Sewage ejector pumps can pump high volumes of sewage to a maximum of about230 metres. Septic grinder pumps are better for low volumes but can pump sewage a much longer distance.

The type of pump needed depends on the type of wastewater that needs to be pumped. Centrifugal pumps are good for sludge wastewater with less particulates or solids. Rotary lobe pumps are great for thicker or more viscous fluids. Progressive cavity pumps and the air-operated diaphragm pumps are also suitable for sludge.

While it is possible to pump mud, it’s difficult and complex, so it requires specialised equipment. A reciprocating piston-driven or plunger-driven pump specially made to pump mud is needed for the task, and these can be expensive.

It’s best to have a pump professionally installed by a licensed specialist. Slurry pumps are intricate systems that won’t work correctly if not installed properly. To avoid issues with your slurry pump system, we always recommend getting it professionally installed.

Slurry pumps are typically larger in size than standard pumps,with more horsepower, and built with more rugged bearings and shafts. The most common type of slurry pump is the centrifugal pump. These pumps use a rotating impeller to move the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.

Fewer, thicker vanes on the impeller. This allows the passage of solids more readily — typically 2-5 vanes, compared to 5-9 vanes on a standard centrifugal pump.

For pumping abrasive slurries, these types of pumps may also be made from specialized high wear alloys such as AL-6XN® or Hastelloy® C-22®. Hardening stainless steel is also a common option for abrasive slurries, with Expanite and Armoly being two hardening processes.

These pumps employ rotating screws to move liquids and solids from one end of the pump to another. The screws" turning action creates a spinning motion that pumps material.

These pumps use a flexible membrane that expands the volume of the pumping chamber, bringing in fluid from an inlet valve and then discharging it through an outlet valve.

Choosing the right pump for your slurry application can be a complex task due to the balance of many factors including flow, pressure, viscosity, abrasiveness, particle size, and particle type. An applications engineer, who knows how to take all of these factors into account, can be a great help in navigating the many pump options available.~ Matthew Sato, Applied Products Sales Manager, Ampco Pumps
