LIQUID PUMPS
Air driven high-pressure pumps up to 79,750 psi.
Maximator Liquid Pumps
Maximator® air-driven piston-style reciprocating pumps are a fast and effective pumping solution capable of delivering a wide range of pressures and flow rates. Our pumps get their power from a compressed air source and combine positive displacement with the capability to hold pressure for long periods of time. A variety of material and seal options allow almost any fluid to be pressurized. Maximator® pumps are rugged and rebuildable and can tolerate all installation positions and most environments.

Pumps for rapid filling and high discharge pressures
-
GPD Pumps
Pressures up to 40,000 psi
GPD pumps are double acting, and feature a single air drive head. They have been specifically designed to give a high discharge flow for fast fill at a relatively high discharge pressure.
The GPD Series Pumps are used in a wide range of applications primarily in Oil and Gas, Refinery, Petrochemical, Steel and Civil Engineering Industries. Common applications are: pressure testing large diameter pipelines, large hose reels and umbilical’s, wellhead control valves, operating Subsea valves, and the charging of hydraulic accumulators.
These pumps are commonly used in Chemical Injection applications for high flow of chemicals such as methanol, glycol and other related chemicals.
GPD pumps are suitable for hydraulic oil, water or chemical applications. High quality materials of construction ensures corrosion issues are kept to a minimum.
The design of the GPD pumps was primarily focused on the ease of maintenance and safe operation. The inlet and outlet check valves are a cartridge style which allows simple, easy exchange and replacement where necessary. Full separation of the air drive section and the hydraulic section is guaranteed because of a distance piece design between these areas thus ensuring no cross contamination can take place.
GPD Series pumps are marked with an EX sign and supplied with a declaration of conformity as defined in 94/9/EC. Enabling them to be used in areas subject to explosion hazards. They are in conformity to Group II Category 2G Explosion group IIB constructive safety.
