Brand new, Cross hydraulic gear motor. Model 40MH05DACSC. Pressure balanced loading plates for high efficiency. Aluminum body for good heat dissipation. Pressure lubricated Teflon impregnated sleeve bearings. Internal check valves eliminate need for case drain at shaft seal pressures under 250 PSI.
Can this motor be driven for use as a pump? I'm sure it would require a case drain line.
A: No this is just a hydraulic motor not a pump.

This motor specs are 4.4 GPM for 1800 RPM 4.8 HP at 1800 RPM, 2500 PSI does it come in a size closer to 6 hp? and what is the gpm at 3000 rpm.
A: The next larger displacement (9-7073-75) produces 7.5 Hp with 6.5 gpm input, 3000 psi, and 1800 rpm. This motor (9-7073-50) would require 6.5 gpm to turn 3000 rpm. At 3000 rpm and 3000 psi, it would produce approximately 8.5 Hp.

Question about item number: 9-7073-50 0.5 cu in CROSS HYD MOTOR 40MH05DACSC I am intending use the motor to drive a load trough belt and pulley. My concern is the type of bearing this motor has: pressure lubricated, Teflon impregnated sleeve. Can this motor be driven with axial loads, pulley type? Thank you.
A: If your application will subject the shaft to side loading and axial loading, it would not fare well and have a decent service life. It would be best to use a jack shaft assembly to isolate the forces away from the motor. These motors have been used with pulleys on the shafts before, but lifespan is directly proportional to belt tension (side load). Axial load will affect the wear plates and lead to a shorter life as well.
