Design flexibility and high quality manufacture


Designed to meet customer needs

Nitrogen pumps are used to suppress various gases, liquids or other dangerous elements whenever a risk assessment dictates.

Our nitrogen pumps use engine power and recovered engine heat to vaporize and pump liquid nitrogen from a liquid nitrogen tank. Our range of units are capable of pumping 60,000 to 540,000 SCFH of gaseous nitrogen with pressures up to 15,000 psi and at discharge temperature of 21°C.

Liquid nitrogen is taken from a nitrogen storage/transport tank by a centrifugal boost pump to a high-pressure triplex pump. High-pressure liquid nitrogen then passes through the unique vaporization system to convert the high-pressure liquid to high-pressure gaseous nitrogen.

Our nitrogen pumps feature a long service interval flame trap meaning typical 8-hour service intervals have been replaced with 1,000 hour service intervals reducing downtime and waste.

We recognise the need for quality bespoke units to suit customer requirements for a range of operating environments and therefore our nitrogen pumps are manufactured to a wide range of formats and specifications and certified to suit all locations around the world.

Our modular build process facilitates faster build times and allows for future-proofed equipment for future advancements in technology such as more energy efficient engines, or changing operating needs.

By investing in nitrogen pumps manufactured by Prior Power Solutions, you are assured of equipment that is built to a high standard with ease of ongoing maintenance in mind and backed by excellent aftersales support.

Our nitrogen pumps are also available to rent through Prior Rental Solutions.

Prior Power Solutions has developed a revolutionary electric-driven nitrogen pumping unit.

Designed and manufactured to meet the requirements of our ever-changing market and reduce overall environmental impact.

The 90k nitrogen pump is a self-contained unit capable of pumping and vaporising 90,000 SCFH at 20°C and pressures up to 10,000 psi when supplied with liquid nitrogen from a suitable tank.

Utilising proven VSD drive technology, our electric driven LN2 units offer exhaust-free operation, without compromising on operational efficiency or accuracy of control.

Designed and certified for use in hazardous areas, the unit is housed in a third-party approved ‘split skid’ type lifting frame/container.

With Prior Power Solutions’ Temperature Shutdown and Over Pressurisation Skids, you can enhance safety and protection of equipment from accidental over-pressurisation or temperature.


Protect critical customer assets and the environment from low or high temperature damage with a Prior Power Solutions Temperature Shutdown Skid.

Designed to immobilise equipment when nitrogen discharge temperature rises or falls below given parameters, our Temperature Shutdown Skids shield nitrogen pumping equipment, pipelines, and associated assets from damage.

Providing an enhanced level of safety to all nitrogen stimulating operations, the unit, which is easily connected to most standard designs, disables the triplex pump in the event of too high or too low downstream nitrogen temperature.

Held in stock for fast worldwide delivery, Prior Power Solutions’ Temperature Shutdown Skids are fully tested, manufactured to high standards and competitively priced. They can be connected to existing units or integrated into a new build design.

  • Stainless steel, lightweight frame
  • ATEX Zone II certified for hazardous areas
  • 7.6m connecting hoses c/w connections
  • 5.7m armoured capillary cable
  • Connects directly to nitrogen pump unit’s over pressure skid connections
  • Easy to operate with adjustable low/high-temperature shutdown controls
  • Compact and lightweight


Providing an enhanced level of safety, Prior Power Solutions’ Over Pressurisation Skid protects against accidental over-pressurisation of the system.

With settings ranging from 10 to 20,000 psi, the unit will shut down nitrogen pumps automatically, mitigating damage caused by over-pressurisation.

Manufactured to operate in ATEX Zone II areas, our over-pressurisation skid fits easily to nitrogen pumps via standard connections and can be manufactured with optional forklift pockets for transportation.

With fast worldwide delivery, Prior Power Solutions’ Over Pressurisation Skids are fully tested, manufactured to high standards and competitively priced. They can be connected to existing units or integrated into a new build design.

  • Robust, yet lightweight stainless steel construction
  • Easy to install and operate
  • ATEX Zone II certified
  • Minimal maintenance required
  • Lifting handles and optional forklift pockets


We offer all aspects of maintenance and repairs from cryogenic overhauls carried out in our state-of-the-art cryogenic service centre and unit recertifications, to a complete overhauls bringing units up to the latest specifications.
