BFM2012 Coolant pump 04259546 02931855

The BFM2012 engine drives the 04259546 water pump bearing and the impeller to rotate through the pulley, and the coolant in the 04259546 water pump is driven by the impeller to rotate together, and is thrown to the edge of the water pump shell under the action of centrifugal force, generating a certain pressure at the same time, and then flows out from the water outlet or water pipe. At the center of the impeller, the cooling liquid is thrown out and the pressure is reduced. The cooling liquid in the water tank is sucked into the impeller through the water pipe under the action of the pressure difference between the inlet of the pump and the center of the impeller to realize the reciprocating circulation of the cooling liquid.
