Centrifugal Pumps

Centrifugal pumps contain one or more impellers that move fluid by rotation and draw fluid into the suction end of the pump and then, through centrifugal force, force it out of the discharge end. This design allows the pumps to be used for a wide range of applications and are preferred for processes that handle low viscosity liquids and high flow rates. Centrifugal pumps can also handle dirty liquids or liquids with low viscosity. Many low-end centrifugal pumps cannot handle fluid containing air, vapors, or too heavy amount of solids. However, DAE Pumps centrifugal slurry pumps can process heavy abrasive solids and work through everything that would normally shut down other pumps. 

DAE Pumps provides the top centrifugal pumps in our submersible pumps, self-priming pumps, dredge pumps, and flooded suction pumps.

Positive Displacement Pumps

Positive displacement pumps (PD pumps), in contrast to centrifugal pumps, do not use impellers to move the fluid. Instead, they utilize rotating or reciprocating parts to push and transport the liquid into an enclosed volume. This design creates pressure, which drives the liquid to its destination. A positive displacement pump is ideal for higher viscosity liquids that transport at a lower flow rate but a higher pressure.

Screw Pumps

The DAE Pumps positive displacement pumps are capable of moving a variety of fluids like slurry and sludge, muds, oils, chemicals, pulps, pastes, wastes, foods, and other liquids. The mechanisms they use to create the suction or vacuum that draws in and captures the fluid in its chamber before passing it through define these pumps. 

We provide the best reciprocating positive displacement pumps and rotary positive displacement pumps on the market for high and low volume and consistency. Our high-quality line of rotary positive displacement pumps includes gear pumps, lobe pumps, vane pumps, screw pumps, and twin-screw pumps. The reciprocating positive displacement pump performance line includes piston pumps, plunger pumps, and diaphragm pumps. Contact our DAE Pumps customer service for help selecting the type, size, and volume of pump for your requirements.

Sludge vs. Slurry

Sludge and slurry are a combination of wet mixtures of liquids and solids. Their consistency and texture are what make them different, but at no point is there an exact consistency that makes one or the other. Where they differ is in the thickness of the material. Sludge is a much thicker substance and is typically soft. Slurry on-the-other-hand is thinner and sloppy. Even though sludge is a thicker material than slurry, they both can consist of the same types of solids that have different shapes, sizes, and abrasiveness.

Both slurry and sludge contain liquids and solids that make up their consistency, and they are in many of the same types of locations. Sludge can be material at the bottom of a wastewater pond or along a river that consists of thick mud or clay containing large rocks and sand. It can also be peanut butter, animal wastes, or pulp material for processing. The same wastewater treatment plant can consist of tanks containing less dense slurry. The slurry can be in lagoons and mine tailings ponds, and slurry can be jello, hazardous waste, and mud.

Slurry vs Sludge

Types of Slurry Pumps

Submersible Pumps: Ideal for moving underwater sludge and rocks, the submersible slurry pumps sit at the bottom of a tank, lagoon, pond, well, or another water-filled environment. Submersible pumps suction out solids and liquids right at the pump itself. The materials are taken in at the intake and pass through a hose connected to its discharge valve. DAE Pumps submersible pumps include a watertight enclosure with the industry’s best o-rings seals for worry-free operations.

Self-Priming Pumps: With the hose head in the water and the other end connected to the pump, self-priming slurry pumps suction the material to the pump, then out through the discharge valve. Self-priming pumps get prime at the pump by electric or diesel motors drawing water to it. They mount to a portable trailer for easy transportation or on a stationary skid.

Flooded Suction Pumps: The flooded suction slurry pump is located outside of a tank or hopper, typically below or as low as possible. Gravity forces the sludge and liquids to the pump, then passes the materials out through the pipe or hose on the discharge end. The flooded suction pump does not require priming because it uses gravity to prime, and it doesn’t use as much power to operate as the other types of slurry pumps because it does not have to draw the material to it. However, a flooded suction slurry pump can get corrosion and require more repairs because there is always liquid filling the pump.

Gear Pumps: Gear pumps are one of the most common types of positive displacement pumps. They provide a constant volume of fluid that passes between the teeth of two meshing gears and the casing. The rotating gears and separation of teeth create a suction that pulls fluid in through the inlet. The gears then trap the liquid and move it around the casing to the discharge or outlet. Each revolution creates consistency in the flow of fluid.

Lobe Pumps: Lobe pumps are like the gear pumps in that fluid flows around the interior of the casing, but they use lobes instead of the gears with teeth. The lobes do not touch each other, thus reducing wear, and they are driven by external timing gear that allows the lobe pump to operate in either direction.

Vane Pumps: Vane pumps use blades, know as vanes, that slide in and out of rotor slots to move fluids. The action creates a suction that pumps fluids. The vane pumps use multiple sets of vanes that mount on an off-center rotor that sits close to the cam wall creating a crescent-shaped cavity on the other side. The blades, which are always in contact with the cam wall, turn with the rotor. As the rotor spins, the vanes slide out when they reach the cavity, trapping fluid. As the vanes reach the end of the open space, they slide back in, and the trapped fluid than to the outlet or discharge valve. 

Screw Pumps: Screw pumps and twin-screw pumps use rotating screws to move liquids and solids from one end of the pump to the other. The turning action creates a spinning motion that pumps material. The twin-screw pumps are identical to the screw pump, but with a dual screw for more power. Screw pumps are capable of high flow rates with very little to no vibration. They provide excellent usage in irrigation, oil production, fuel injection, and fuel transfer applications.

Piston Pumps: The piston pump uses a piston to draw in liquids and solids by creating a vacuum in the chamber to suction in the materials, then pushing them out the other end. The piston repeatedly moves up and down inside the pump chamber to pump the material. The DAE Pumps piston pumps use high-quality O-rings to ensure reliable performance. These pumps can be uses for high-pressure washing, oil production, paint spraying, and other low viscosity liquids.

Diaphragm Pumps: Diaphragm pumps use a flexible membrane that expands the volume of the pumping chamber bringing in the fluid by opening the inlet valve, then compresses to push out the materials through the outlet valve. The hermetically sealed DAE Pumps diaphragm pumps are safe for pumping hazardous and corrosive liquids.

The DAE Pumps Advantage

Slurry Hose

The DAE Pumps slurry pumps and sludge pumps can be used in a variety of applications. They outperform the same pumping requirements of primarily water type pump by holding a distinct advantage over them. Our slurry and sludge pumps primary purpose are to move materials like rock, sand, sludge, slurry and other debris of various sizes. 

DAE Pumps non-clogging slurry pumps provide reliable, long-lasting suction power over ordinary pumps. Ordinary pumps cannot handle the variety of materials that pass through our slurry pumps. Strictly water pumps that suck-up rocks, sand, sludge, and other types of debris tend to clog and seize up, destroying the entire unit, but our slurry pumps keep moving material without interruption.

We provide the largest selection of non-clogging slurry pumps that work best for your specific project requirements. Our experienced, knowledgeable, and friendly team can help you with everything you need.
