Product catalog summary
About Maximator:
Maximator is a leader in high-pressure technology, focusing on air-driven liquid pumps and gas boosters for industries like automotive, chemical, and oil & gas. Their products adhere to pressure equipment, machinery, and ATEX directives and are ISO 9001 certified.

Product Overview:
The document details the LGP, SLGP, and GLGP series of liquified gas pumps, suitable for refrigerants in both liquid and gaseous states, and usable in explosion-proof areas.

Key Features:
  • Pressure regulation via manual or pneumatic valves.
  • Flame arrester for flammable fluids.
  • Easy installation and low maintenance.
  • Optimized to prevent icing and phase transitions.

Selection and Use:
Selection criteria include operating pressure, pump capacity, air drive pressure, fluid type, and temperature. Maximator provides design and selection advice for specific applications.

Safety and Compliance:
Pumps feature flameproof enclosures and flame arresters, tested to DIN EN 60079-1 standards, to prevent explosions in flammable environments.

Options and Variants:
  • FS – Flame safety device.
  • RS – Reduced Stroke.
  • FEC – For Extreme Cycling.
  • LT/LTA – Low Temperature options.
  • SS – Stainless Steel components.

Sealing Materials:
Available sealing materials include NBR, HNBR, EPDM, FKM, FFKM, and PTFE, each with specific temperature and media compatibility.

Performance Graphs:
Performance graphs illustrate outlet pressure and flow rates for each pump series under various conditions.

Refrigerant Specifications and Recommendations:
The document lists refrigerants, their Global Warming Potential (GWP), safety classes, and recommended sealing materials. Key refrigerants include R32, R50, R170, R290, with safety classifications like A2L, A3, and A1.

High Pressure Pumps:
Air-driven high-pressure pumps can generate pressures up to 7,000 bar, suitable for explosion-protected areas, and do not consume power during long pressure holding periods.

Gas Boosters:
Designed for oil-free compression of industrial gases and compressed air up to 2,400 bar, suitable for explosion-protected areas.

Rental Units and Power Packs:
Maximator Power Packs for liquids and gases generate high pressures safely and inexpensively, with Liquid Power Packs reaching up to 4,000 bar and Gas Power Packs up to 2,100 bar.

Testing and Production Systems:
Includes autofrettage machines, leakage and burst pressure testing technology, gas filling systems for hydrogen applications, and high-pressure forming machines.

International Support:
Maximator GmbH offers international support through partner companies and high-pressure technology experts, with contact information available on their website.

Application and Function Liquified Gas Pumps – the Maximator-Concept The Maximator LGP (Liquified Gas Pump) series was developed for use with refrigerants. The design of these pumps is based on the mode of operation of gas compressors in combination with proven highpressure pump technology. The technology has been optimized for the compression of liquid and gaseous fluids, so that the pumps of the LGP series can compress and convey both aggregate states. The SLGP and GLGP pumps are also optionally available with reduced stroke. On the one hand, this reduces the size of the pump and, on the other...
