Description

The pneumatic powered HPU is designed for use with sour gas, sweet gas, or instrument air at pressures rang – ing from 60 psi to 2000 psi. The system converts pneu – matic pressure into stored hydraulic power by means of a pneumatic driven hydraulic pump. The system is totally self-contained and requires no electrical power, pressure switches or motor starters. Pneumatic pow – ered HPUs are used frequently on offshore platforms. The advantage is that actuator sizes can be reduced sig – nificantly because the low pressure pneumatic power source has been converted to high pressure hydraulic power.

Applications: BOP Control System, Emergency Shut – down Systems, CALM Buoy Power Units.
