Marathon Electric offers Hydraulic Pump Motors

Marathon ElectricMarathon Electric is excited to announce the introduction of our new Hydraulic Pump Motors. These motors are designed with highly engineered adapter pads allowing the motor flange to mount to SAE A, B, and C flanges for both 2 and 4 bolt configurations. The motor shafts will have a standard SAE shaft configuration that will vary per frame size. Special internal spline adapts can be used to change from one spline configurations to another. Internal keyway shaft extensions will also be available.

Applications include but are not limited to pumps & pumping equipment, oil royalty traders, oil & gas extraction and oil, gas field machinery, axial piston pumps, gear pumps, gerotor pumps, variable volume pumps and hydraulic power units.
