Type of Hydraulic System: Open-center
or closed-center
Flow:
Minimum: 26.5 l/min (7 gpm)
Recommended: 30.3 to 37.9 l/min (8 to 10 gpm)
Maximum: 37.9 l/min (10 gpm)
Filtration: 10 micron (nominal)
Pressure Relief Setting: 172 bar (2500 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).
Greenlee Utility tools 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 37.9 l/min (10 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
172 bar (2500 psi) at your tool's maximum flow.
Locate the pressure relief valve in the supply circuit
to limit excessive hydraulic pressure to the tool.
