The feed pump is a new type of crankshaft pressure plunger diaphragm pump with adjustable flow rate.
Adopting a variable frequency motor combined with a cycloidal pinwheel reducer for transmission, the crankshaft drives the plunger rod to perform continuous reciprocating motion, and the pump body adopts a double cylinder symmetrical balance structure.
Significant improvements have been made to the vulnerable parts of the pump, such as using oil and temperature resistant rubber to make the diaphragm, which has doubled its service life, and using polyurethane stainless steel composite material for the valve seat; The plunger sealing ring is made of nylon composite rubber, and the plunger is processed by grinding. The valve ball is made of stainless steel material, which greatly increases the service life of the feed pump.
