What we refer to as slurry is basically a liquid containing solid particles. When you want to pump this slurry, you'll have different requirements than when you are pumping just dirty water. A wastewater pump is not able to handle the slurry's solid particles. That is where slurry pumps come in. Slurry pumps are a heavy and robust version of centrifugal pumps, capable of handling tough and abrasive duties.

Slurry pumps can be used to move mixtures of liquid and solids in many industries with a broad spectrum of applications such as mine drainage, dredging of settling lagoons and pumping of drilling mud.

Slurry Pumps can be used:

• -To pump a medium where abrasive particles are present
• -To transport solids, hydraulically
• -To pump the end product in a process
• -To keep clean up sumps clean from solid

• -Wear parts with high chrome content is essential when pumping abrasive slurries. But more is not always better - much over 25 percent and the impeller becomes brittle.
• -Hydraulic efficiency is as important as the material since efficiency correlates to wear. A swept-back design of the impeller vanes minimizes the separation of solids from the carrying fluid for a more homogenous flow. This results in a slower rate of wear.
• -By increasing the size of the volute, the speed at which the medium moves is reduced. This lower velocity translates into lower wear.

The submersible alternative offers a number of advantages over the dry installed and even the semi-submersible sump pumps. The submersible pump is more flexible and more efficient than the alternatives.
