Min. Speed2 rpm 15 10 10 10 10 10 5 5 5

Simultaneous intermittent torque and intermittent speed maximums are NOT recommended.

Maximum return pressure without drain line or maximum pressure in drain line for all models--continuos: 0-100 rpm: 1800 psi (124 bar); 100-300 rpm: 1100 psi (76 bar); 300-600 rpm: 725 psi (50bar); >600 rpm: 365 psi (25 bar); Intermittent: 0-max rpm (1800 psi (124 bar). The pressure on the shaft seal is equal to the average of the inlet pressure and the return pressure.

16B splined shaft or 7/8 in-13T splined shaft is recommended for operating torque of 2500 in.lbs. (28 daNm) or more.

2Operation at lower speeds may be slightly less smooth.

The built-in check valves ensure that the return pressure on the shaft seal never exceeds the pressure in the return line.

16B splined shaft or 7/8 in-13T splined shaft is recommended for operating torque of 2500 in.lbs. (28 daNm) or more.
