Hydraulic Power Units

We will design and manufacture hydraulic power units to suit your specifications. As a responsive, engineer lead company, we are able to accommodate bespoke requirements whilst maintaining fast turn-around and cost competitiveness.

Our workshop facilities enable us to assemble systems with a power range of 7.5kW-500kW[jd1] , fully tested at our facility. We design to both industrial onshore and offshore requirements – relishing the different challenges faced in each sector. The range of typical offshore system features include:

  • IP rated stainless steel enclosures
  • Hazardous Area / ATEX compliant components
  • Stainless steel tank and fittings
  • Offshore paint system
  • DNV 2.7-1 certified frame
  • Seawater / marine environment compatible cooling systems

Many operators have come to accept the hazards and operating costs associated with running standard hydraulic power units due to the lack of available time to specify or procure bespoke systems. At Pryme Group, we continually update our designs with the latest technologies and apply design improvements from each project to the next. Available system improvements include:

  • Reduced noise and vibration
  • Reduced power consumption
  • Improved cooling efficiency
  • Improved fluid conditioning
  • Elimination of leak points
  • Space and weight saving

We would be delighted to offer you an improved solution for your system, whether you are looking to design a new application or upgrade or replace existing units.

Hydraulic Manifolds

We recognise that many new and existing hydraulic system designs can be improved by using bespoke manifold blocks in the place of traditional valve stacks and assemblies. When correctly designed the benefits are seen not only in the neatness of the original equipment but in the subsequent reliability and ease of diagnostic testing.

We can supply cost-effective manifolds to suit your existing circuit, or we can provide a full design service. The advantages of using bespoke manifolds include:

  • Compact design enables space saving
  • Reduced number of connections eliminates common hydraulic leak points
  • Multiple test points allow for system investigations and monitoring
  • Cost saving

Manifold Block Design

Experience and skilled engineers specialising in bespoke manifold design consolidate multiple valve stacks into a compact leak free manifold. Manifolds are designed using 3D CAD programs allowing interface connections to be easily checked and aligned and ensuring rapid and effective transfer from design to manufacturing.


Manifold blocks can be supplied with full certificates of conformity, pressure test and 3.1 material certification. We are familiar with coating and painting procedures to meet offshore operating requirements and will always work in accordance with client project specifications.

Bespoke Hydraulics Equipment

Pryme Group Hydraulics is able to undertake the complete or partial scope of work for the design, manufacture and commissioning of bespoke equipment including test rigs and functional prototypes.

We have experience of working with a wide range of industries to develop new technologies including Renewable Energy, Subsea, Defence and Aerospace.  The examples of challenges undertaken include:

  • Active heave compensation systems
  • Variable load test rigs
  • Sea state simulators
  • Fatigue test rigs
  • Combined test and flushing rigs
  • Hydraulic ring main

The scope of our involvement can include any or all of the following services:

  • Design and specification of components
