BZW120/65

BZW120/65 water injection pump is our company's leading plunger pump type supporting underground explosion-proof motor. The coupling is directly connected, the structure is compact, the bearing bush structure is adopted between the crankshaft and the connecting rod, and the forced lubrication system is configured to ensure that the crank part is fully lubricated and suitable for continuous work. The structure of the hydraulic end is optimized, and the pump head does not need to be disassembled to replace the wearing parts, which is convenient for use in occasions without hoisting facilities. The plunger sealing part is equipped with a cooling system, which prolongs the service life of the plunger and the seal.
