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.

Submersible dewatering pumps are vital in construction, mining and quarrying applications enabling users to remove water, sludge, and slurry. Here, Hrishikesh Kulkarni outlines the main considerations for specifying reliable submersible pumps.

Construction managers and engineers are increasingly under pressure to increase efficiencies across their sites and they can make huge gains by using the right equipment for the job, so getting the correct specification for a reliable submersible pumps can make all the difference.

What liquid needs pumping? The first consideration is the nature of the liquid being pumped as this has a major impact on the type of pump. Important factors to consider include general composition, the concentration and size of suspended particles as well as the liquid’s pH level, temperature, and chemical content. For example, is it water with fine particles or a much thicker fluid, and how aggressive a media is it?

Sludge  Viscous mixture of liquids and solids, including soft wet mud and by-products of industrial or refining processes. Sludge has a solid weight of approximately 40% and particle sizes up to 5.08 cm diameter. Slurry semi-liquid mixtures typically loaded with sediment and fine particles of materials such as manure, cement, or coal. Slurry has a solid weight of approximately 70% and particle sizes up to 6.35 cm diameter.

The higher concentration of solids is best handled by slurry pumps which are specially designed for handling corrosive and abrasive media. If the liquid is particularly aggressive then ensure the pump is robust and designed with protection features such as hardened, clog-free impellers, and wear-resistant. However, if the fluid to handle contains solids with a size below 50 mm a sludge pump, such as Atlas Copco’s WEDA S50, will be better suited for the job.

What are the capacity requirements? One of the most important performance considerations is the flow requirement, ie how much liquid needs to be moved and how quickly? For example, a pump with a maximum flow rate of 138 m3/h (such as Atlas Copco’s WEDA D50) will remove water from a pool that is 36 m3 in 15 minutes. However, a pump with a flow rate of 350 m3/h (such as the WEDA D80) would empty the pool in just 6 minutes.

For the best value and efficiencies, the pump selected should be able to handle the flow requirements with enough capacity to cope with fluctuations in water level as well as versatility to manage the demands of different sites. A pump which is over-specified and can handle a much higher flow capacity will be unnecessarily expensive and will not provide the most cost-effective solution. On the other hand, a pump that has been under-specified will struggle to transport the media and wear out more quickly, resulting in a shorter life span.

What is the distance and the elevation that the fluid needs to be pumped? Over what height does the fluid need to be pumped and how far does it need to travel? This will have an impact on the pressure that the pump needs to deliver to ensure it can pump efficiently and reliably. The greater the distance the water needs to be pumped, the more friction is created, which results in pressure loss from the pump. Pumps need to overcome gravity resistance as well as friction losses.

If the suction lift required for dewatering with a surface pump is more than approximately seven metres, a submersible pump should be considered instead. Designed to be totally submerged, it uses the proximity and pressure of the surrounding water to aid fluid movement through the hose and therefore less energy is needed to move the water. When specifying, check the manufacturer’s published pump curve, which shows head height against flow rate, to ensure it covers the required duty point.

What is your energy source?If mains electricity is available, an electric pump will be the best and most efficient choice in most cases. Electric submersible pump, such as Atlas Copco’s WEDA pumps, are the simplest, most energy-efficient and most economical approach, providing high power in light and compact packages.

If the site is remote and prone to a fluctuating mains supply consider a pump whose motor and starter are equipped with inbuilt electrical protection against varying voltage, phase failure and human error.

Careful consideration of the liquid being pumped, together with the physical demands of the application such as flow, elevation and distance the fluid travels mean engineers will be able to select the most appropriate pump for the job and achieve maximum performance. Other factors to consider also include the energy economy, durability and servicing expense for each pump offered.

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.

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.

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.

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.

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.

A chopper pump is a centrifugal pump which is equipped with a cutting system to facilitate chopping or maceration of solids that are present in the pumped liquid. The main advantage of this type of pump is that it prevents clogging of the pump itself and of the adjacent piping, as all the solids and stringy materials are macerated by the chopping system. Chopper pumps exist in various configurations, including submersible and dry-installed design and they are typically equipped with an electric motor to run the impeller and to provide torque for the chopping system. Due to its high solids handling capabilities, the chopper pump is often used for pumping sewage, sludge, manure slurries, and other liquids that contain large or tough solids.

The chopper pump was invented in 1950 by the Danish company Landia. The pump manufacturer, Christian Ølgaard, developed a pump with a special knife system to meet the need for macerating and pumping manure in agricultural applications. Manure with high solids content, containing straw and sawdust, would clog up other types of pumps, causing unstable operation in an environment which required high reliability.

As the need for the pumping of difficult media expanded to other industries, so did the use of the chopper pump in both dry and submersible applications and in various industries, including meat, paper and food processing, as well as the automobile industry, biogas, chemical plants, municipal wastewater and prison lift stations.

A chopper pump is operated by a drive unit (e.g. electric motor, hydraulic motor, power takeoff (PTO)), which turns the impeller and the cutting system. An open impeller design is used to successfully pass the macerated solids or thick slurry. A set of hardened steel cutters is installed externally to the pump suction in order to macerate all solids prior to entering the hydraulic parts of the pump. A chopper pump should not be confused with a grinder pump, which uses its impeller as part of the cutting mechanism. Grinder pumps are typically used for light weight sewage applications, whereas chopper pumps are used for tough solids handling applications.

The chopping system consists of a set of rotating cutters that are keyed to the shaft and work in conjunction with the stationary cutters, which are bolted to the suction plate. A system of mechanical seals are used to prevent the pumped liquid from entering the motor. The pump can either be connected to a pipe, flexible hose or lowered down a guide rail so that the pump sits on a coupling foot (aka base elbow), thereby connecting it to the discharge pipe.
