Standard hydraulic power unit (HPS)
This hydraulic power unit uses a standard range of modular components for easy specification, assembly and maintenance in the most demanding industrial applications. With motors up to 30 kW, flow rates to 100 Litres/minute, tank capacities to 180 litres and pressure capability to 250 bar, we can offer a hydraulic power unit system to meet most industrial requirements including:
- Launch recovery systems
- Bailers and compactors
- Agricultural processing machinery
- Punching machines
- Injection moulding machines
- Lifting equipment
- Marine applications (test rigs, drilling rigs)
We offer a design, build and installation service. Most of our Hydraulic Power Packs work covers replacements and upgrades of existing installations. We can also offer design and build electrical and electronic control cabinets (through our partners) giving customers a single point of reference on projects that need to be coordinated.
Other units are built as part of larger projects or to be installed on various machines we build.
Recent hydraulic power packs unit work includes units for shredders, dock levelers, scissor lifts, hydraulic ring main and bailing presses. We also produce hand operated power units for use as back up to electrically operated units in case of failure or on applications where electricity is not the preferred option.
Unit options and specs
The hydraulic power unit components have been carefully selected by ehc to give an economic solution from our large stocks. As we construct units for many industrial applications we have an ever growing component base and can cater for the majority of builds.
The units cater for a selection of tanks ranging from 16-180 litres and pressures up to 250 bar, with flow rates of up to 100 litres/minute.
The AC motors within the units are all IP55 as standard and multi mount B35 configuration. Motor options such as Anti-condensation heaters and Ex protection are possible so please remember to enquire about these when you spec up your unit.
Wide range of applications covered
Our standard power units are suitable for a wide range of applications; one of these being the marine based Launch Recovery System. This system is equipped with an umbilical winch which has to be able to accommodate the whole length and diameter of the remotely operated vehicle umbilical. Our hydraulic power units power the hydraulic winch motor that, in turn, controls the winch itself which is responsible for pulling in the remotely operated vehicle (ROV).
Product testing and oil filtration
We are one of the few companies producing hydraulic power units that fully test our units on testing rigs before dispatch, ensuring power and voltages are correct. We also carry out regular oil filtration tests to ensure that particulate contamination is avoided.
These test stages make sure that our units reach our customers in optimal working order and help to lengthen the operational life of our products.
Bespoke design options
Where the hydraulic power unit (HPU) does not offer all the hydraulic features required, we can design and manufacture a full hydraulic power unit system using our proven CAD design software and renowned technical expertise.
We hold a vast library of modular parts which can be used to populate 3D solid unit models making the customization process easy and enables us to standardize designs, leading to a quick turnaround of customized units. This gives our end user a solid, dependable unit with the EHC stamp of approval.
