Among the many types of pumps the firm offers, its W series of centrifugal pumps features an innovative auger feed and impeller vane design.
Operating a pump below or above BEP parameters can produce a number of problems ranging from premature bearing, packing, or gland failure to accelerated wear on impeller vane edges.
Case in point, as illustrated by process equipment supplier Weir Minerals: Centrifugal pump impeller vanes are designed to meet the incoming flow and accelerate the fluid.
This tooth helps break up stringy materials such as rags, scrapes them off the impeller vanes and passes them through the pump - all without impacting performance or interrupting service.
Because of the interest of a broad based efficiency range for varying building loads, the effect that the number of impeller vanes and their orientation has on off-design conditions (Johnson 2006) was a pump hydraulic characteristic that was considered during the hydraulic design phase.
Smoother inlet flow and uniform velocities within the impeller vanes significantly lowers the net positive suction head (NPSH) characteristics, extends inlet and associated throatbush wear life, and improves overall performance.
The removable basket strainer catches any foreign material which might clog the impeller or cause damage to the impeller vanes or pump seals.
The semi-open, self-cleaning design keeps the leading edges of the impeller vanes unobstructed, where fouling often sets the stage for clogging.
Cavitation is most likely to occur at the pump inlet, near the eye of the impeller, and along the trailing sides of the impeller vanes.
