• 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.

            GD4 pump is one model pump of GD Series pump, and it's specially designed for LPG,  the pressure ratio is   4:1, the maximum outlet pressure of GD4 pump is 32 bar, the flow rate is 70litre/min
