Maximator GPD Series High Pressure Pumps
Double-acting high pressure pumps delivering up to 2,770 bar (40,200 psi) with high flow capacity. German engineered, stocked and serviced locally by Maximator Australia.
Double acting | Single or double air drive head | Pressures up to 2,770 bar (40,200 psi) | Flow rates up to 48 L/min
The Maximator GPD Series High Pressure Pumps are air-driven, double-acting pumps designed to deliver high flow at high pressure, making them ideal for fast fill applications and demanding chemical injection duties.
Built for pressures up to 2,770 bar (40,200 psi), the GPD range is available with either a single or double air drive head, operating from 1–10 bar (14.5–145 psi) air supply. These pumps are capable of handling hydraulic oil, water, or aggressive chemicals such as methanol and glycol, with corrosion-resistant materials and a cartridge-style check valve design for simplified maintenance.
The pumps also feature a distance piece design to guarantee full separation of the air drive and hydraulic sections, preventing cross-contamination. Models marked with EX certification are suitable for use in hazardous areas (Group II, Category 2G, IIB) in accordance with ATEX standards.
Applications include:
-
Pressure testing of large-diameter pipelines, hose reels, umbilicals, and wellhead control valves
-
Subsea valve actuation and accumulator charging
-
Injection of inhibitors such as methanol and glycol in wells
-
High-flow chemical injection (methanol, glycol, and related chemicals)
-
Aviation and automotive fluid testing (brake fluid, Skydrol, transmission fluid, power steering)
-
Industrial leak testing and refinery maintenance
All GPD Series pumps can also be integrated into Maximator Australia’s turn-key high-pressure test systems, ensuring a complete, compliant, and locally supported package for chemical, oil & gas, and industrial applications.
