Impeller Types

Types

Vortex F
Ideal for smaller sewage pumps as the liquid does not pass through the impeller. Can handle stringy matter, paper, rags etc. with large clearances ensuring long life. Also suitable for high speeds due to the impeller being balanced.

Single Channel K
Ideal for sewage pumps of larger sizes. Liquid passes through eye of the impeller, but large clearance within the impeller ensures free passage.

Two Channel Z
Generally used for surface water applications or for handling sewage on very large pumps. More efficient than vortex or single channel impellers.
