Maximator G-2 Series High Pressure Pumps
Air-driven high pressure pumps up to 7,000 bar (101,500 psi), featuring a single-acting, dual air drive head for extreme pressure applications.
Single-acting | Dual air drive head | Pressures to 7,000 bar (101,500 psi)
The Maximator G-2 Series high pressure pumps are engineered for water and oil applications up to 7,000 bar (101,500 psi). Featuring a single-acting, dual air drive head, the G-2 Series achieves double the outlet pressure at the same 10 bar (145 psi) air drive input compared to the standard G Series.
Constructed with stainless steel heads and plungers, the G-2 Series combines German precision with proven reliability in Australian conditions. Standard polyurethane seals ensure durability in oil service, while UHMWPE seals with Viton® O-rings are available for extended water service life. Operating from a standard air supply of 1–10 bar (14.5–145 psi), these pumps automatically hold pressure without further energy consumption — reducing downtime and lowering operating costs.
Options
-
Seal materials: Polyurethane (oil use), UHMWPE + Viton® (water service), specialised seals for aggressive fluids
-
Inlet configuration: Bottom inlet (standard); side inlet available (standard on G500-2 and G60–G150-2 models)
-
Special connections: NPT threading available
-
Air control units: With filter, regulator, gauge, and shut-off valve (C2 option)
-
Air safety valve: Integrated option for outlet over-pressure protection
-
Additional customisation available on request
All G-2 Series pumps can also be fully integrated into Maximator Australia’s Custom Test Systems and Turnkey Solutions, ensuring compliance, safety, and performance across mining, hydrogen, oil & gas, defence, and industrial testing environments.
Examples of Applications
- Hydrostatic testing of valves, tanks, vessels, hoses, gauges, cylinders, aerospace components
- Burst and cycle fatigue testing
- Calibration of pressure gauges and transducers
- Water jet cutting and cleaning
- Leak testing at ultra-high pressures
- Emergency shutdown systems for oil & gas wells
- Accumulator pressurisation and component testing
- Operation and control of well service and well head equipment
