Maximator G-D Series High Pressure Liquid Pump

• Double acting
• Single air drive head
• Pressures to 4,500 bar (65,250 psi)
• They are suitable for use in zone 1, category 2G/2D IIC TX explosion-proof areas (Temperature class depending on medium temperature).

Examples of application for the G…-2 Series hydraulic pumps include:

• Hydrostatic tests: Valves, tanks, pressure vessels, pressure switches, hoses, pipes & tubing, pressure gauges, cylinders, transducers, well casings, BOPs, gas cylinders and components from the Aerospace technology.
• Burst and Cycle fatigue testing for parts mentioned above
• Calibration: Pressure gauges and transducers
• Water jet cutting and cleaning
• Leak testing
• Emergency shutdown systems for Oil & Gas Wells
• Pressurisation of accumulators for testing numerous components
• Operation and Control of well service and well head equipment

G…D Pumps

• Double acting
• Single air drive head
• Pressures to 4,500 bar (65,250 psi)

G…D pumps are double acting, single air drive head. They are characterised by the same features as the G pumps single acting, single air drive head types, but they have less pulsations and deliver approx. 50 % more flow.

G…D pumps are available with polyurethane seals, UHMWPE seals with Viton O-ring for water use are available as option. Models G10D – G35D come standard with bottom inlet, side inlet is available as option. Models G60D(S) – G150D(S) are only available with side inlet. For air drive pressures of 14.5 psi (1 bar) minimum to 145 psi (10 bar) maximum.
