HSB double-direction and double-speed piston pump

　　HSB double direction and double speed poiton pump is a simplex duplex plunger power pump.The woring principle of RZB rotary pump is as follows.The relative movement between piston and cylinder liner leads to volume change and produces pressure.

　　The pressure combined with the controlling system offer the machine intake and output functions during the process of double direction movement of the piston.Users can alter pumps intake and output direction by changing the position of intake-output vales.

　　The form of structure:HSB double-direction and double-speed piston pump constitutes power generagor,crank case,piston,valve components,sealing,and control components.
