Polyurethane Impeller for High Head Slurry Pump

Impeller parts is arguably the essential part of your centrifugal pump, and slurry applications can be particularly hard on it. Because of the abrasive nature of the slurry, it’s critical that you choose the right impeller so you can operate effectively without constant breakdowns.

Slurry Pump Polyurethane impellers have proven their worth in a variety of industries: chemical, electric power, coal, metallurgy, and building materials, to name a few. Polyurethane is corrosion and wear-resistant, allowing it to withstand seawater, acid, alkali, and salt.

Slurry Pump Polyurethane impellers have a longer life, which reduces the frequency of replacing them. And because the material is smooth, there is little chance that the slurry will stick to the impeller and clog the pump.

Slurry Pump Impellers Types:

Slurry Pump Closed Impellers
A closed impeller, also called a shrouded impeller, has one circular plate on each side. It ideal for pumping water and other liquids at higher head pressures. While the closed design is initially very efficient, it loses its efficiency as the wear ring clearance increases. The design of this impeller makes it more difficult to modify and because its internal parts are hidden, it’s hard to inspect for flaws.

Slurry Pump Open Impellers
An open impeller has blades that are attached to a hub. This design looks very similar to a boat propeller or a fan.  They are ideal for situations in which the impeller needs to be cleaned on a regular basis or there is a risk of blockage. Though an open impeller tends to have low efficiency, its efficiency can be regularly maintained through impeller clearance adjustment.

Slurry Pump Semi-Open Impellers
A semi-open impeller has a circular plate attached to one side of the blades. It is ideal for use with trash and debris laden liquids.
