What is the self priming pump?
The self priming pump is a self priming centrifugal pump;It is designed with an external casing that “floods” the inner pump or volute. The casing is filled with liquid usually the same as the liquid to be pumped and the pump is ready to go .The air separates from the liquid and is discharged from the casing. When all the air in the suction line has been displaced, the pump is dynamic and delivers flow like any other centrifugal pump.
The self centrifugal priming pump which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, and only need to ensure that the pump body has a quantitative priming liquid before work. Different liquids can use self-priming pumps of different materials.
The centrifugal pump that can automatically pump water up without filling the suction pipe with water has a smart structure and is easy to disassemble. It is a widely used type of acid alkali resistant self-priming pump.
Can self priming pump run dry?
YES, Can run dry.
The self-priming pumps on the general market cannot run dry without water;but JK;s new launched self priming pump MG series can run dry.
The run dry self priming pump uses the centrifugal force generated when the impeller rotates to transport the liquid, A cooling circulation system is added. The internal circulation uses the impeller as the power to form a self-circulating channel. The main function is to use the liquid medium in the pump body. The water source in the pump body can be used to circulate and cool the mechanical seal to effectively protect the mechanical seal. The outer circulation adopts ASTM standard pump special coolant, and uses the principle of thermodynamics to form a self-circulation mechanism to achieve the purpose of circulating cooling and protect the mechanical seal. The cooling box is made of FRPP or PVDF acid and alkali resistant materials, which are one piece injection , So as to break the shortcomings of traditional self-priming pumps, cannot run dry,motor burnout, liquid leakage, environmental pollution, and increased maintenance costs.
