Among the many types of pumps the firm offers, its W series of centrifugal pumps features an innovative auger feed and
impeller vane design.
Any vapor bubbles formed by the pressure drop are swept along the
impeller vanes by the flow of 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.
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.
