Ideal for moving underwater sludge, abrasive slurries, 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.
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.
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 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. 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 are like 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 use blades, know as vanes, that slide in and out of rotor slots to move fluids. This 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. These blades, which are always in contact with the cam wall, turn with the rotor. With the spinning of the rotor, 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 thus moves to the outlet or discharge valve.
Screw pumps and twin-screw pumps use rotating screws to move liquids and solids from one end of the pump to the other. Because of the rotating, turning action, the spinning motion is what pumps the 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.
The piston pump uses a piston or pistons 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. Pistons repeatedly move up and down inside the pump chamber to pump the material. DAE Pumps piston pumps use high-quality O-rings to ensure reliable performance. These pumps are used for high-pressure washing, oil production, paint spraying, and other low viscosity liquids.
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 diaphragm pumps are safe for pumping hazardous and corrosive liquids.
