Brand new, Cross hydraulic gear motor. Model 40MH18DACSC. 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.
Hi can I use this motor to power a former engine driven welder?. The engine was 20 HP . I need 1800 RPM for the machine to work properly. Is this the best type of motor for this application? I am planning on using an open loop system with a pressure regulator.
A: If this motor is operated at 1800 rpm at 2500 psi, with no losses calculated it would produce approximately 19.9 Hp. If a continuous 20 Hp is required the system pressure may need to be raised slightly to increase torque, and therefore horsepower.

Can I buy just the base flange that has the mounting tabs on it for these Cross motors?
A: We have two mounting L-brackets for these motors. We do not carry any of the motor pieces themselves.

If I were to use a variable speed pump driven off a gas engine, could I use this motor to power a garden tractor thought it's existing axle / reduction system (54:1)? If heat is a concern, could an oil cooler be fitted?
A: Without any other information, we cannot say. It seems reasonable as long as flow, pressure, and thermal restrictions are considered.

If took a motor, your item #9-7073-180 and coupled it to an engine to use as a pump and routed the fluid to an identical motor, with a valve, your Item #: 9-7458, will I be able to use this a variable speed unit to drive a small tractor?
A: These motors were not designed to operate in a closed loop system as you describe. Overheating and cavitation would irreparably damage the motors in short order.
