High pressure stainless steel fluid power equipment for the international offshore oil and gas industry.

Oil Pumps

Benefits

Our wide range of axial piston oil pumps provide cost-effective solutions to your flow and pressure requirements. From the 0.23 l/m SM pump to the 139 l/m XH pump with pressures up to 690 bar for most ranges and up to 1040 bar for the X pump.

  • Bombs can rotate in any direction.

  • Horizontal or vertical mounting.

  • Options for full stainless steel, full carbon steel, or combination aluminum/carbon steel construction.

  • SM, SMLP, LM and LMLP pumps can be coupled to AC or DC motors, eliminating the need for a housing and coupling unit.

Thermal Relief Valves

  1. Types 14460 and 14470 Integrated Check/ Thermal Relief Valves. These check/thermal relief valves are designed to directly replace a single separate unit of check and thermal relief valves used in wellhead control systems.

  2. ​Type 14480 Thermal Relief Valve. Designed to provide pressure control in systems subject to thermal expansion, a special interlock feature eliminates the need to strip or disconnect the valve during system proof testing.

Superior Pressure Intensifiers

  1. PI39-TS type pressure intensifier for surface operation. An innovative product that increases pressure by a factor of up to 5 without external power. Works with any water-based fluid or mineral/synthetic oil. Inlet pressures up to 270 bar and outlet pressure up to 700 bar. 

  2. PI73-TS type pressure intensifier for topside operation. An innovative product that increases pressure by a factor of up to 7 without external power. Works with any water-based fluid or mineral/synthetic oil. Inlet pressures up to 420 bar and outlet pressure up to 1380 bar. 

  3. PI73-TS model selection tables. Assists in specifying necessary features such as pressure boost factor, inclusion of pilot operated vent valve, inlet and outlet connections. 

  4. Animated interactive presentation. Shows how fluid flows in a step-by-step presentation of pressure intensifier operation.
