Air Driven Hydraulic Pump
Double acting-high flow
Pressure range: 4.8~320Mpa
Twelve ratios available
Best price, high quality
GD series air driven liquid pumps are high pressure reciprocating plunger pumps of double acting, single air drive head model. Air drive pressure from 3bar(43.5 psi) to 8bar(116 psi) maximum.
They are characterized by the same features as the G series pumps with single acting, single air drive head, but they have less pulsations and deliver approx. 50 % more flow. Provided for operating pressures up to3, 200 bar(46, 400 psi). The same with G series, they are suitable for application with high pressure requirements.
