Designed for reliability Uniglide-e pumps feature a keyless drive design that eliminates the impeller key, which is a common cause of shaft failure due to fretting and fatigue failures. 1. The type of impeller used in a centrifugal pump will depend on the intended use of the pump. stream <> Impellers can be designed to impart various flow characteristics to pump or tank media. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. They have an impeller which rotates in a casing of a special shape. A worn impeller on a water pump can reduce the amount of coolant flow through the engine. while sweeping from the hub to the shroud. Design a new pump to satisfy special applications such as boiler-feed, nuclear coolant, pipeline, large circulator, condensate, secondary recovery, etc. Thanks for sharing, I am delighted with the work that you have done to write this article. The design of centrifugal pump is focus to Impeller Design. Water pump efficiency can depend greatly on the impeller and housing design. The inlet diameter at the eye of the impeller is D = 8 in. In order to control the shape, additional design variables are introduced to change the leading edge region (more elliptical shapes vs. circular ones) and to vary the thickness from the leading edge to the trailing edge. Water Pump Design: Geometry for a Shrouded Impeller.
