Abstract
A centrifugal pump to improve the efficiency of fluid flow, and minimize long term wear on the pump by progressively increasing fluid pressure as fluid moves from an eye of an impeller towards diffuser blades, into the volute and out through an outlet. The fluid pressure is increased by progressively increasing the volume through which the fluid travels. A tear-drop shaped volute casing surrounding the diffuser and impeller creates a pocket of maximum pressure just below the outlet. A dampener can be provided to dampen the vibration of the motor. A cylindrical basket strainer can be provided with a flat face abutting against the volute casing to distribute pressure evenly. A clamp ring can be provided to easily seal and access the basket strainer using a plain rod.
