Dredge Pump

Determine the perfect combination of slow pumping (to reduce wear) and fast pumping to prevent solids from settling and clogging.

Definition of dredge and slurry pumps

To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.

What we mean by slurry is basically a liquid containing solid particles. When you want to pump this slurry, there are different requirements than when pumping only dirty water. A waste water pump cannot handle the solid particles of a slurry. This is where slurry pumps come in handy. >Slurry pumps are heavy duty and robust versions of centrifugal pumps, capable of handling tough and abrasive tasks.

Dredge pumps are designed to transfer large quantities of fluids and solids.
