oil-gas reuse pump / gasoline recovery pump / self-priming pump

Application
ZKB series oil-gas recovery vacuum pump is a relatively consummate pump for oil-gas recovery, working under the ambient temperature at -40~60°C. It can be used separately or as a part of oil-gas recovery system in gas stations, which is mainly used for oil-gas recovery, to reduce pollution and save energy.
With the growing requirement on taking advantage of environmental pollution and energy well, this oil-gas recovery vacuum pump will be applied to this field widely.
Structural Characteristic
Characteristic of ZKB series oil-gas recovery vacuum pump: a shaft drived by motor is fixed on the pump body, and its one end in the pump body is fixedly connected a crank which is jointed to a connection rod; a piston in liner with reciprocating motion is fixed on the top of the connection rod, and the liner is fixed in the pump body; a valve seat assy above the piston has inlet valve and outlet valve which are check valves. Besides, the inlet cavity and outlet cavity on the pump body are connected with the inlet valve and outlet valve respectively; through a pipeline, the inlet cavity is connected with the coupling of an air eliminator, and one end of the coupling is connected with the hose through the hose coupling; the hose with internal and external casing is connected with nozzle.
