H4665A/42191 Submersible Pump
Specifications (cont'd.)
Hydraulic Power Source
Do not exceed the following hydraulic power source maximums:
• Hydraulic flow: 30 l/min (8 gpm).
• Pressure relief: 138 Bar (2000 psi).
• Back pressure: 13.8 Bar (200 psi).
Failure to observe this warning can result in severe injury or death.
Type of Hydraulic System ..................................... Open-Center or Closed-Center
Flow
Minimum ............................................................................. 19 l/min (5 gpm)
Recommended ......................................................... 19 - 30 l/min (5 - 8 gpm)
Maximum ............................................................................. 30 l/min (8 gpm)
Filtration ............................................................................. 10 Micron (Nominal)
Pressure Relief Setting .......................................................... 138 Bar (2000 psi)
Back Pressure (Maximum)* ................................................... 13.8 Bar (200 psi)
* 13.8 Bar (200 psi) is the maximum agreed standard back pressure for the
HTMA (Hydraulic Tool Manufacturers Association). Fairmont tool will
operate satisfactorily at this standard.
1. Maximum hydraulic fluid temperature must not exceed 60 C (140 F).
A sufficient oil cooling capacity is needed to limit the hydraulic fluid
temperature.
2. Hydraulic flow must not exceed 30 l/min (8 gpm). Install a flow meter in
the return line to measure the rate of hydraulic flow before using the tool.
3. Pressure relief valve setting must not exceed 138 Bar (2000 psi) at your
tool's maximum flow. Locate the pressure relief valve in the supply circuit
to limit excessive hydraulic pressure to the tool.
