Apex were commissioned to design and manufacture a bespoke 37KW 3 phase hydraulic power unit (HPU) which can deliver 190 lpm (50 US gallons) at 275 Bar (4000 psi)

The HPU was a equipped with a pressure compensated axial piston pump on a 1000 litre reservoir, which for safety and environmental reasons came with a purpose built bund. The bund retains oil from any future leaks up to the capacity of the reservoir.

HPU Specification

For a HPU of this size oil cooling is essential and so a 1” BSP air blast cooler with 4 bar bypass check and oil temperature gauge were installed. The cooling system has its’ own independent or “offline” pump and motor which enables it to continue to cool after the main system has been shut down. This offline system is also fitted with its’ own filtration unit which again can circulate after shutdown.

As with most HPU’s it was also fitted with an oil level indicator, filler breather, electric motor anti vibration feet and safety relief valve. A low oil level switch was built in to protect the unit from damage in a low oil situation.

It was painted to the customers own specification and came with full operating/maintenance manual.

After Sales

The unit was delivered within 5 weeks but it has many years of service ahead of it. Apex’s after sales parts and maintenance teams are ready to support our customers to ensure a high return on investment.
