Sanitary centrifugal pump it own self heating radiator system, it is not need water cooling pump body, and it is because of its simple structure, small volume, low operating cost, good performance has won the acceptance of most users. A lot of times, we buy the pump to buy only suitable for oneself, also do not buy those product quality very, sometimes quality very good buy can not use, return trouble. So depending on what kind of pump you want to buy, it's a very important first step.

The centrifugal pump is currently used most of the centrifugal pump, because it is in the tank. It consists of a turbine pump, a pressure relief valve and a residual pressure one-way valve. The turbine pump is driven by an electric motor, which sucks the fuel out of the tank. The motor needs to be cooled and lubricated by fuel. If the oil quantity is reduced, the motor may be burnt. The pressure relief valve is used when the outlet pressure of the centrifugal pump is overrated, the pressure relief valve will open and discharge the excess oil; The function of residual pressure one-way valve is when the centrifugal pump stops working, the valve is closed, and the residual oil pressure is retained so as to start again. The centrifugal pump is controlled by the engine speed signal.
