Rental Hydraulic Power Pack
This system is ideal for operating large valves, which require large volume of fluid and few cycles. Typical use is for BOP testing and other valve package testing. A Mob/ Demob fee of 8 000 NOK
- Pumps will not run continuously.
- Pumps will run almost continuously.
The 6 off 50 litre accumulators are of the piston type. The bank will supply appr. 105 litres of hydraulic fluid to the system with pressure from 210 to 140 Barg.
To precharge the accumulators, bleed off hydraulic pressure, connect N2 supply via special charging kit to the charging valve on top of each of the accumulators, one at time. Then precharge the accumulators to 140 barg.
To check the N2 precharge pressure, bleed off hydraulic pressure and use the same charging kit (it has a pressure gauge).
