Hydro Pneumatic Pumps


Our offer

MAXIMATOR hydro pneumatic pumps have been developed to meet the needs of manufacturers in the automotive, medical, food, plastics, but also chemicals and petrochemicals sectors. All pumps operate with compressed air or neutral gas with a pressure of 1 to 10 bar. Depending on the pressures and flow rates, these pumps are in single or twin cylinder configuration with one or more engine pistons. They have been designed to be installed in an ATEX zone.

Our pumps allow:

Outlet pressures of 40 to 7000 bar

Displacements from 0.6 to 508 cm3

Flow rates (theoretical) from 0.28 to 48 l / min

Fields& applications

MO and S pump series up to 1000 bar: oil use

Rugged construction, lightweight and wide range of pressure ratios make this series of pumps ideal for powering a variety of oil / hydraulic operations. They are available in single or double acting models.

  • Lifting function
  • Clamping device
  • Tensile test and pressurization
  • Hydraulic press

M and G series pumps up to 7000 bar: oil and water use

M and G series pumps are available in single or double acting models with single, double (M and G series or triple (only M series) pneumatic drive heads and stainless steel materials, making it an excellent choice for water application.

  • Hydrostatic tests – valves, tanks, pressure devices, pressure switches, flexible hoses, pipes and tubes, manometers, gas cylinders.
  • Burst and cycle fatigue tests of the above components
  • Calibration of manometers and transducers
  • Leak test
  • Pressurization of pressure vessels to test various components

MSF, GSF and GX series up to 1450 bar: Pumps for chemical and offshore applications

These two series of pumps are similar to the M and G series described above. MSF and GSF pumps feature an isolation chamber and PTFE seals to meet the specific requirements of chemical applications. The GX series consists of high flow pumps designed for tough installations and constructed with environmentally resistant external components. They are ideal for offshore applications with cold contact stainless steel parts and corrosion resistant external components.

  • Coolant injection
  • Aeronautical and automotive tests – Brake fluid, Skydrol
  • Transmission fluids and power steering fluids
  • Chemical fluid transfer and pressurization

DPD series pumps:

The DPD series pumps are large, double-acting pumps that deliver a high flow rate at high pressure up to 2100 bar (30,450 psi).

  • Waterjet cutting in intermittent service
  • One or two component injection pumps
  • Test pressure generation for chuck-extraction machines

Our strengths

The advantages of MAXIMATOR pumps:

Pressure regulation via manual air regulation or pneumatically operated valve

Operation with compressed air allows use in explosion-proof areas

The pump automatically stops working when the preselected end pressure is reached.

Suitable for most liquids and liquefied gases

No energy consumption while maintaining pressure

No heat generation when maintaining pressure

Easy installation and trouble-free handling

Low maintenance

Our technology

MAXIMATOR pumps are ideal for a wide variety of oil, water and chemical applications. MAXIMATOR pumps operate with air (or neutral gas) at a driving pressure of 1 to 10 bar (14.5 to 145 psi). The principle of operation is similar to that of a reciprocating amplifier in which the control of the piston in the final position is regulated by a 4/2 pilot valve.
