what is the difference between tyrash mud pump for sale

Successfully dewatering your pipeline, mining, excavation or industrial construction application requires knowledge of the terrain and environment you’re working in for dewatering with your industrial trash pump to flow seamlessly.

It can be a daunting task to figure out which trash pump is right to remove standing water from your jobsite. Choosing the wrong trash pump for your application can result in weak performance, or even damage to the pump’s internal components.

Before you get started with selecting the right industrial trash pump for your application, you will need to understand the difference between what is referred to as a “semi trash pump” and a trash pump.

In a nutshell, semi-trash pumps can handle smaller debris, whereas trash pumps are designed to handle larger debris. Semi-trash pumps operate similar to centrifugal pumps, but have a larger discharge opening for small debris and sentiments to pass through.

If you’re pumping water that contains larger solids, such as pebbles, stones, leaves and twigs, you will require a trash pump with a larger hose diameter.

The rule of thumb for selecting an industrial trash pump is selecting a model where the hose diameter is twice the diameter of the solids that will be passing through the unit, which is measured in inches. For example, a 3″ trash pump has the capacity to handle solids up to 1 1/2″ in diameter.

Another reason why you will need to determine the kind of terrain you’ll be operating on is because it will help you choose the material of hosing you’ll need with your trash pump.

As mentioned above, selecting the right hose size is one of the most important aspects to consider when choosing the right trash pump for your dewatering needs.

Another factor to consider when it comes to hosing is choosing the correct length of suction hose. There is a common misconception that the longer the suction hose is, the better the dewatering outcome will be. However; using the minimum amount of suction is best (20 – 40 ft. of hose is ideal).

While selecting the correct size of industrial trash pump and hose, and determining the jobsite terrain are some of the most important factors to consider when choosing the right trash pump for your dewatering needs, some other important factors to take into consideration are:

Consider maintenance-friendly features which allow for quick resolution on-site to prevent downtime – is there easy access to components which may become clogged or need to be replaced during operation?

Consider whether it is more cost-beneficial to rent or purchase your trash pump. Need help figuring this out? Read our blog on Should I Rent or Buy My Construction Equipment.

For dewatering applications requiring long continuous run times, choose a trash pump with self priming and long-run time capabilities when left unattended for low risk operation

If you are dewatering lake or creek water, consider using screens on the end on the suction hose to keep out garbage, debris, fish or other aquatic life

By carefully taking these factors into consideration, you’ll be able to quickly, successfully and cost-effectively dewater your jobsite with zero downtime.

Mud Pumps come in both electric and gas / diesel engine drive along with air motors. Most of these pumps for mud, trash and sludge or other high solids content liquid dewatering, honey wagon and pumper trucks. Slurry and mud pumps are often diaphragm type pumps but also include centrifugal trash and submersible non-clog styles.

WARNING: Do not use in explosive atmosphere or for pumping volatile flammable liquids. Do not throttle or restrict the discharge. Recommend short lengths of discharge hose since a diaphragm mud pump is a positive displacement type and they are not built with relief valves.

Trash pumps can be an integral part of a solids control system. These pumps are designed to pump large amounts of water that contain solids such as mud, leaves, sticks, sand and sludge. A trash pump is commonly a heavy-duty, portable centrifugal pump that features deeper impeller vanes and a larger discharge opening than other styles of pumps. Trash pumps are capable of moving hundreds or thousands of gallons per minute, all while processing materials with suspended particulates that would typically clog other styles of pumps.Mud Technology International, Inc. builds a line of trash pumps to accommodate projects of varying sizes and challenges.

Each pump is compatible with all of Mud Technology International"s Recycler Systems and can be adapted to work in conjunction with most other brands of solids control equipment.

The various models of Mud Technology International trash pumps can move from 500+ gpm to 800+ gpm and have a 4" fitting to transfer slurry to the recycling system. Each model has a completely submersible head and flooded suction (unit does not have to be primed.) All units run on 480V, 3-phase power, with a 100" weatherproof cord.

A water pump is perfect if you need to pump just water. But when you mix in debris, mud, sand and other solids, you risk clogging up and damaging your water pump beyond repair.

Enter the dirty water pump. Also known as a trash pump, a dirty water pump is designed to move water that contains solids. So when you need to move sand, sludge, muck and debris, a dirty water pump is the solution.

Semi-trash pumps can move small debris and items no bigger than about 5/8 of an inch. Think sandy and slightly muddy water, rather than water with leaves and pebbles. The pump housing cannot cope with larger items, so we recommend you use a strainer to avoid clogging the hose.

Trash pumps are designed with larger impeller veins and pump housing to move leaves, pebbles and twigs with ease. No grinding or pumping – the dirty water pump simply transfers the water (and debris) from one place to another. It’s still recommended to use a hose and strainer though, so you can easily open up and remove larger items from the pump. The debris should be less than 30mm in diammeter.

If you’re moving sludge or draining a pond, diaphragm pumps have got it covered. Unlike traditional dirty water pumps that use centrifugal force, a diaphragm pump created a vacuum effect that sucks in and ejects the water. Because of this, it can handle water, mud, leaves, twigs and more.

Yes. You can also consider a Submersible Pump for moving dirty water. A submersible pump is a pump that can be fully submerged in water. The major advantage to a submersible pump is that it never has to be primed, because it is already submerged in the fluid. The are commonly used for industrial/construction site trash pump applications as they allow debris (up to 25mm) to pass through.

While the task at hand will determine the type of dirty water pump you need, always choose a dirty water pump with a quality design, proven reliability and a manufacturers’ guarantee. Don’t opt for a cheap, low quality pump without national service agent support.

DISCLAIMER* Please note, this advice is general in nature and we strongly recommend consulting the product manual and where relevant, a professional installer.

The standard diesel pump won’t work if you need to remove mud, sand or other debris from water. To deal with thick, sludgy water, you will need a trash pump that is specially designed. Pumps like these are usually portable, making them easy to move around your site and set up. It will be easier to choose the right trash pump for your dewatering needs if you understand how trash pumps work.

Pumps designed for use with petrol and diesel are designed to pump clear water. They can be affected by contaminated water filled with sand, soil, and solid objects, causing the pump to clog or the motor to break down, resulting in costly repairs or replacements. Solids like leaves, branches, pebbles, and twigs are no problem for centrifugal trash pumps, solving the problem of dewatering and preventing flooding.

During trash pumping, dirty water is sucked in, separated from contaminants, then emitted as filtered water. Depending on the type of trash pump you’re using, you can separate trash in different ways. Diaphragm pumps create an air vacuum, while portable trash pumps use centrifugal force to create an area of low pressure that draws water into the pump. During the ejection process, liquid is sucked through an impeller to remove solids. Trash pumps can be powered by diesel, petrol, or electricity.

Choosing a water pump should be based on the kind of water you need to remove. Some water pumps can handle harder debris than others. Here are three trash pumps that you could use:

Semi-trash pumps –suited for lightly muddy or sandy water, these less powerful pumps are capable of handling light dewatering tasks, but may run into problems if larger stones or objects are present.

Centrifugal pumps –the most common type of pump, small trash pumps are portable and can handle solids up to 25mm, although larger models can handle debris up to 100mm. Compared to other types of dewatering pumps, they have deeper impeller vanes and discharge openings.

Diaphragm pumps –larger than centrifugal pumps, air diaphragm pumps come in sizes from 25mm to 75mm. There are also air-driven submersible pumps available. They are typically used for draining ponds, sewage, and chemically contaminated water.

Electric Trash Pumps, sometimes referred to as Mud Pumps, can save on cost when power is available, making an electric pump a good choice for long-term pump rental. Electric Trash Pumps run quieter, thus being an ideal solution when noise is a concern. Rental Trash Pumps work well for pumping water containing large amounts of particulate and debris. Applications where a Mud Pump is well suited are sewer bypass systems and digester tank pumping, or pumping drillers mud at oil and gas drilling sites.

A convenient multi-tool is provided for easy removal and installation of the pump case, for tightening and removal of the priming plug and drain plug, and for tightening and removal of the hose coupling.

High performance mounts minimize vibration, keeping the pump from “walking" away or “burying" itself in soft soil conditions. The reduced vibration also reduces wear on components, increasing the pump"s durability.

The strainer allows up to 1 1/16 in. solids to pass through, as well as a large volume of water, helping to prevent clogging. Made of steel to withstand tough conditions.

Mud recycling systems were once considered optional equipment. Environmental regulations continue to become more stringent and we must all responsibly make a contribution to protect our fragile ecosystem.

Using mud recyclers are a valuable asset to drilling contractors, as well-conditioned drilling fluid can save resources, time and money by reducing the amount of water and chemicals needed by reusing your bentonite and water. This helps maintain borehole stability with consistent mud properties through the entire circulation of the fluid and you haul off mainly the drilled solids, not the entire mud returns, including the liquid.

Drillers considering a mud recycler often ask: “Where do I start?” There are factors to consider before purchasing (or renting) a mud recycler, and, just like sizing the drill rig, sizing the recycler is equally important to your success. The following are some of the questions to ask yourself before making your purchase:

These factors are important to know so that you use a recycler that is sized to clean the mud and protect the components on the rig, pump and cleaner.

Drilling rigs are generally classified as “maxi,” “midsize” and “compact. While you can put a maxi recycler with a compact rig, it would not be advisable to do the reverse. Lesson: size accordingly.

As a general rule, size the recycler cleaning capacity to one and a half to two times the pumping volume (max gpm) of the triplex pump. HDD drillers normally run thicker fluids due to the low vertical height and long horizontal lengths of their bores; thicker fluid makes it more difficult for the shakers and cones to process (separate) the solids from the liquids. This is largely due to the natural coating ability of bentonite — It wants to encapsulate the solids and “hold on” to them. By upsizing the recycler, the solid particles have a second or third opportunity to process through the mud recycler for removal before going back to the rig.

Some mud recyclers provide an “onboard” mud pump that was sized specifically to the recycler. This enables the driller to use all available drill rig horsepower toward the rotation and push-pull of the drill pipe, thereby not “robbing” it for an onboard triplex pump.

Most recyclers today use orbital, elliptical or linear motion shakers, and each has a place in different drilling scenarios. With that being said, linear motion shakers generate high G-Forces and are especially effective in shallow formation sections where high-volume, heavy solids are encountered, and have the ability to remove the solids quickly.

When choosing a linear shaker for your mud system, look for a long runway (area of length from the front of the shaker to the end where the cuttings dump off). The longer length shaker bed allows extra time for solids to separate from the liquid, and result in drier solids leaving the mud system for disposal. You can also increase the angle of the shaker bed by five degrees to further increase the travel time of the solids.

Proper shaker screen selection enhances the results of the mud recycler, and, combined with the G-Force of the shaker, works in tandem to maximize solids dryness. In the past, shaker screens were sized by mesh size.

Before buying your recycler, do your research, talk to other drillers, decide what you need and you will be able to make the best decision for you and your company.

Example: 40 mesh screen had 40 openings per square inch of screen area. As a measurement, this left room for a lot of unknown variables, including questioning what gauge wire was used in the manufacture of the screens. The wire gauge altered the size of openings on the screen surface and resulted in changing the size of the solids that the screen could pass or “cut.”

The industry needed a consistent way to measure the “cut point” of the screens, and the API introduced the D100 designation, or D100 “cut point” using the average micron cut of the shaker screen, depending on the wire. Two examples are the CRX Oblong and UF square meshes.

Identification of particle sizes from core samples taken on each drilling location provides drillers valuable information and aids in selecting screens. Drilling contractors should carry a couple of testing tools to measure the effectiveness of a of the mud recycler while drilling. These tools are: a Marsh funnel and cup, sand content kit and mud weight scales. Taking mud samples from the return pit or possum belly before the mud is processed, the underflow and overflow of the cones and the clean mud tank help monitor the effectiveness of each component of the recycler, and the driller can make component adjustments to achieve maximum efficiency.

In addition to the shale shakers, another way to size the processing capability of the mud recycler is to look at the hydrocyclone. Depending on the size of the mud recycling system, cone size will be 4, 5, 10 or 12 in. Each size cone has a micron “cut point,” and represents the size of the smallest particle the cone can “pull.” Four- and 5-in. cones have a 20-micron “cut point,” and 10- and 12-in. cones have a 74-micron “cut point.” Smaller mud systems normally have two section tanks, with a ”dirty” tank under the scalping shaker and a “clean” tank under the mud cleaner (shaker with desilting cones), while larger systems can have three section tanks with scalping, desanding and desilting.

One hydrocyclone processes liquid at a rate of 50 gpm/ 4-in. cone, 80 gpm/ 5-in. cone, and 500 gpm/ 10-in. or 12-in. cone. Some manufacturers’ volume amount for their respective cone sizes may differ than those cited herein, but these are the most common within the industry for reference purposes.

Maintaining proper pressure is essential for the hydrocyclones to work effectively, with the normal operating pressure range for 4- and 5-in. cones of 30 to 40 psi; 10- and 12-in. cones of 23 to 35 psi. Pressure above 45 to 50 psi cause premature internal cone wear, and lower pressure down around 20 to 22 psi is a “red flag” that you better consider rebuilding the centrifugal(s) to maintain pressure in the optimum range.

Borehole returns require transport into the recycler via a “trash” pump properly sized for the job. Different pumps are available, but the three most common are: 1) submersible, 2) semi-submersible, and 3) aboveground centrifugal with a foot valve. Totally submersible pumps are generally the smallest in size, have a flooded suction to help in priming, and though the most convenient option, are usually the most expensive. Semi-submersible trash pumps still have a flooded suction, but the drive motor is not submerged into the fluid. Semi-submersible pumps work well, but are heavier, and longer than the submersible pumps.  Another option is an above ground centrifugal pump with a foot valve, and once primed, is dependable and normally used on larger recyclers for their increased volume capacities.

If your drilling crew has never operated a mud recycler, be sure that you are provided with training and try renting a unit to make sure it is the right “fit” prior to purchase. Be familiar with the maintenance requirements of your mud system; usually the owner’s manual is sufficient, but inquire if the manufacturer offers training videos, onsite or plant training sessions and — the most important — technical support.

A manufacturer should stand behind the equipment its builds so don’t settle for a warranty less than one year. Ask questions about the warranty prior to finalizing the purchase.

In an age where protection of our planet is a major concern, so should your choice of mud systems. Choose a recycler that is respectful to the environment and leaves your jobsite as clean as possible.  Do your research, talk to other drillers, decide what you need and you will be able to make the best decision for you and your company.
