Charging Pump For Hydraulic Starting
Usage:
6L8721 (American Bosch Number RPA300374)
Pressure adjustment range ... 1500 to 3000 psi(10 300 to 20 700 kPa)
Normal pressure to start the pump automatically (cut-in) ... 2500 psi(17 000 kPa)
Normal pressure to stop the pump automatically (cut-out) ... 3000 psi(20 700 kPa)
Output at 3000 rpm of pump and pressure of 3000 psi (20 700 kPa) ... .5 U.S. gpm(2.0 litre/min)
Maximum suction height (head) ... 3 ft.(0.91 m)
NOTE: The oil RETURN passage near the mounting flange must be above the horizontal center line. This position makes correct lubrication of pump parts.
