Hydraulic power unit manufacturing

We design and build hydraulic power units from 25 to 15,000 litres. Circuit diagram, 3D design, manufacturing, piping and on-site commissioning from a single source.

01

Design, manufacture, commission on site

A unit starts with its circuit diagram. We size the pump, motor, valves and tank for the load, speed and duty cycle, then design the unit in 3D and solve the layout up front, so that it fits its place in the engine room or on the line first time.

We work on existing systems too: pump and control conversions for energy efficiency, capacity upgrades and refurbishment.

Marine power units

For the Tersan Shipyard NB1109 trawler we designed and built the 3,000-litre, 4 × 110 kW main hydraulic power unit with Danfoss components. On a longliner fishing vessel we delivered the hydraulic and automation control system for the emergency closing doors, complete with accumulator station and on-board piping.

  • Main units for trawl and deck machinery
  • Hatch, ramp and crane units
  • Emergency closing door (EMG) systems
  • Yacht and superyacht units
  • Modular stinger hydraulic system
03

Industrial units

A selection of the units we have built, mainly for iron and steel plants:

  • Billet pusher and rolling mill units
  • Aluminium billet casting unit
  • Hydrotest and pipe calibration units
  • Dam gate and sliding gate units
  • Clutch and brake system units
  • Scrap press and hammer units
  • Slitting line and lathe units
  • Rubber mixer and warping machine units
04

Valve and accumulator stands

We also build the valve stands, manifold blocks and accumulator stands that complete the power unit. With our site piping and flushing crews, the unit is handed over as a clean, working system.

03 Frequently asked

Questions,
answers.

What capacities of hydraulic power unit do you build?

From compact 25-litre units to multi-pump main units with 15,000-litre tanks. We define the capacity together from flow, pressure and duty cycle.

Which component brands do you use?

As a Danfoss Power Solutions authorized distributor we mainly use Danfoss (Vickers) pumps and valves. Because we are project-driven, we select what suits the application and also work with brands named in the specification.

Do you commission the unit on site?

Yes. Piping, flushing, pressure testing and commissioning are carried out by our site crew; supervision-only service is also available.

Can you refurbish our existing power unit?

Yes. We survey the system and engineer pump, valve and control upgrades for energy efficiency, capacity or reliability.
