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.

Dewatering pumps are centrifugal pumps installed in a building that is situated below the groundwater level, to reduce the water level and then maintain it at this level. One example is in underground mining in which water penetrating into the adits is pumped up to the surface.

This rig features a Mission 4-by-5 centrifugal pump. Courtesy of Higgins Rig Co.Returning to the water well industry when I joined Schramm Inc. last year, I knew that expanding my mud pump knowledge was necessary to represent the company"s mud rotary drill line properly. One item new to me was the centrifugal mud pump. What was this pump that a number of drillers were using? I had been trained that a piston pump was the only pump of any ability.

As I traveled and questioned drillers, I found that opinions of the centrifugal pumps varied. "Best pump ever built," "What a piece of junk" and "Can"t drill more than 200 feet with a centrifugal" were typical of varying responses. Because different opinions had confused the issue, I concluded my discussions and restarted my education with a call to a centrifugal pump manufacturer. After that conversation, I went back to the field to continue my investigation.

For the past eight months, I have held many discussions and conducted field visits to understand the centrifugal pump. As a result, my factual investigation has clearly proved that the centrifugal pump has a place in mud rotary drilling. The fact also is clear that many drilling contractors do not understand the correct operational use of the pump. Following are the results of my work in the field.

High up-hole velocity - High pump flow (gpm) moves cuttings fast. This works well with lower viscosity muds - reducing mud expense, mixing time and creating shorter settling times.

Able to run a desander - The centrifugal"s high volume enables a desander to be operated off the pump discharge while drilling without adding a dedicated desander pump.

6. Sticky clays will stall a centrifugal pump"s flow. Be prepared to reduce your bit load in these conditions and increase your rpm if conditions allow. Yes, clays can be drilled with a centrifugal pump.

7. Centrifugal pumps cannot pump muds over 9.5 lbs./gal. Centrifugal pumps work best with a 9.0 lbs./gal. mud weight or less. High flow rate move cuttings, not heavy mud.

The goal of this article has been to increase awareness of the value of the centrifugal pump and its growing use. Although the centrifugal pump is not flawless, once its different operating techniques are understood, drilling programs are being enhanced with the use of this pump.

If you wish to learn more, please talk directly to centrifugal pump users. Feel free to call me at 314-909-8077 for a centrifugal pump user list. These drillers will gladly share their centrifugal pump experiences.

Self-priming pumps are used in various industrial and commercial facilities, from steel mills, power plants, and sewage treatment facilities to wineries, breweries, and more. Common applications include: Pumping water, fuels, clear or gray water, raw sewage, industrial wastewater, and more. Liquid transfer systems.

A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. The PCPD pump uses drilling fluid (commonly referred to as drilling mud, or just mud) to create eccentric motion in the power section of the motor which is transferred as concentric power to the drill bit. The mud motor uses different rotor and stator configurations to provide optimum performance for the desired drilling operation, typically increasing the number of lobes and length of power assembly for greater horsepower. In certain applications, compressed air, or other gas, can be used for mud motor input power. Normal rotation of the bit while using a mud motor can be from 60 rpm to over 100 rpm.

Normal mud motor construction consists of a top sub, which connects the mud motor to the drill string; the power section, which consists of the rotor and stator; the transmission section, where the eccentric power from the rotor is transmitted as concentric power to the bit using a constant-velocity joint; the bearing assembly which protects the tool from off bottom and on bottom pressures; and the bottom sub which connects the mud motor to the bit.

A mud motor is described in terms of its number of stages, lobe ratio and external diameter. Stages are the number of full twists that the stator makes from one end to the other and the lobe ratio is the number of lobes on the stator, to the number of lobes on the rotor (the stator always has one more lobe than the rotor). A higher number of stages indicates a more powerful motor. A higher number of lobes indicates a higher torque output (for a given differential pressure), a lower number of lobes indicates a reduction in the torque produced but a faster bit rotation speed.

The use of mud motors is greatly dependent on financial efficiency. In straight vertical holes, the mud motor may be used solely for increased rate of penetration (ROP), or to minimize erosion and wear on the drill string, since the drill string does not need to be turned as fast.

The majority of mud motor use is in the drilling of directional holes. Although other methods may be used to steer the bit to the desired target zone, they are more time-consuming, which adds to the cost of the well. Mud motors can be configured to have a bend in them using different settings on the motor itself. Typical mud motors can be modified from 0 degrees to 4 degrees with approximately six increments in deviation per degree of bend. The amount of bend is determined by rate of climb needed to reach the target zone. By using a measurement while drilling (MWD) tool, a directional driller can steer the bit to the desired target zone.

The PCPD stator, which is a major component of the pump, is usually lined with an elastomer. Most of PCPD pump failures are due to this elastomer part. However, the operating conditions

The mud motor may be sensitive to fouling agents. This means that certain types of drilling fluids or additives may ruin the motor or lower its performance. One particular example, as mentioned above, would be the use of oil based mud with the mud motor. Over time the oil degrades the elastomers and the seals in the motor.
