HANST pneumatic booster pump consists of a large driving piston, a small gas plunger and reversing control valve. The driving piston and the gas plunger are connected through a transmission rod, are controlled by the reversing valve to do reciprocating movement automatically. Under the action
of large piston and small plunger, the driving gas on the piston is transmitted to the plunger, thereby increasing the gas pressure at the outlet. This pump is commonly used for gas transmission, gas pressurization, gas recovery, gas filling, pressure testing, blasting testing and sealing test.
