HYDRAULIC POWER UNITS (HPU)
Custom-built to meet your needs
We specialise in custom Hydraulic Power Unit (HPU) builds, designing and manufacturing to customers’ exact specifications. Flow, pressure and power ranges can all be tailored to customer requirements as well as meeting the following compliance options:
- Rig Safe
- Safe Area
- Zone I
- Zone II ATEX
Our hydraulic power units can be packaged as portable, open, enclosed or sound treated (acoustic) and can be designed/manufactured to work in ambient temperatures ranging from -40°C to +5o°C. HPUs can be diesel engine or electric motor driven.
Due to weight restrictions with some applications there can be a need to replace the single skid where all the components are housed within one frame to a split skid type where the prime mover is on one skid and the hydraulic components on another.
We only use the highest quality, reputable hydraulic components such as Parker, Linde and Bosch Rexroth, and as build completes, all units are extensively tested.
Hydraulic Power Units manufactured by Prior Power Solutions can include safety features including: Pyroban exhaust gas cooling kit, fire suppression system, and fire and gas detection system.
The systems around hydraulics are evolving
Electrical integration is becoming the norm, allowing for greater levels of control and monitoring.
Engines are developing all the time to be more fuel efficient with cleaner technology, however in higher level ATEX environments, these engines cannot be used, which is where electric motor drives come in. Variable frequency drive technology is rapidly advancing to better match the speed and torque capabilities of a diesel engine.
More environmentally friendly fluids, ‘bio-oils’ or water-based hydraulic fluids are becoming imperative. Whilst these have been around for a long time, compatibility of seals and clearances is a design challenge we rise to. However, as the technology of these bio fluids becomes more and more advanced a wider range of components become compatible.
