Self Priming Centrifugal Pump
Standard centrifugal pumps have no self-priming capability and are incapable of pumping when water flow is discontinued in the suction pipe. The oval shaped self-priming pump has weak self-priming force at locations where back pressure is present, and the higher the pump head, the harder to self-prime the water.
Applications
Self-Priming Centrifugal Pumps can be used even under extreme conditions. They can be used, for example, as chemical pumps for liquids containing air, pumps for mixing air bubbles in an aeration system (i.e., gas-liquid two-phase flow pumps), condensate pumps, drain pumps, and pumps for extraction from sealed tanks.
