M46 pumps are designed for medium power applications with maximum loads of 345 bar [5000 psi].
These pumps can be combined with other products in a system to transfer and control hydraulic power.
M46 pumps provide an infinitely variable speed range between zero and maximum in both forward and
reverse modes of operation.
M46 pumps are compact, high power density units. All models use the parallel axial piston / slipper
concept in conjunction with a tiltable swashplate to vary the pump’s displacement. Reversing the angle
of the swashplate reverses the flow of fluid from the pump, reversing the direction of rotation of the
motor output.
M46 pumps may include an integral charge pump to provide system replenishing and cooling fluid flow,
as well as servo control fluid flow. M46 pumps feature a range of auxiliary mounting pads to accept
auxiliary hydraulic pumps for use in complementary hydraulic systems.
M46 pumps offer proportional controls with either manual, hydraulic, or electronic actuation. An electric
three-position control is also available.
