Eternal Hydraulic Parker Denison M4 Series Vane Motor
Eternal Hydraulic M4 Series single/double Vane Pump high pressure vane motors are perfect interchange replacements for Denison® M4 series vane units. Our vane motor units are available in a variety of different displacements with multiple torque, shaft, porting and port connection options. These units are capable of working with pressures up to 2500 psi and maximum rpms up to 4000. We also stock replacement cartridge kits, seal kits and shaft kits for these units..
These units interchange with Denison®M4 series and Metaris MM Series.

HIGH STARTING TORQUE EFFICIENCY
The high starting torque efficiency of vane type motors makes them especially applicable in load hoist winch drives, swing drives and propulsion drives. This high starting torque efficiency allows the motor to start under high load without pressure overshoots, jerks and high instantaneous horsepower loads.
HIGH VOLUMETRIC EFFICIENCY
Vane motors begin life with high volumetric efficiency and maintain that efficiency throughout their operating life.
LOW TORQUE RIPPLE AT LOW SPEED
When operating at very low speeds on applications such as swing and load hoist drives, the vane motor exhibits very low torque ripple.
2 AND 3-SPEED VERSIONS AVAILABLE
The M4DC, because of its unequal size cartridges, allows the use of-3 speed operation. This makes them more applicable in traction drive circuits to replace manually shifted gear-boxes. 2-speed motors are available in a wider range of ratios than standard gear motors.
BALANCED DESIGN
Vane, rotor and cam ring are pressure balanced to increase life and efficiency over full speed range.
INTERCHANGEABLE ROTATING GROUPS
Rotating groups may be easily replaced to renew the motor or change displacement to suit altered requirements for speed or torque.
REVERSIBLE ROTATION
The motors may be stopped or reversed repeatedly and rapidly driving or braking the connected shaft load at controlled torque levels.
WIDE SPEED RANGE
Starting to maximum RPM, with full torque capability during acceleration.
PORTS AND MOUNTING
Conform fully to SAE J744c (ISO-3019-1) standards to simplify refitting and installation.
FIRE RESISTANT FLUIDS
Are easily used in the standard M3B and M4* versions of these motors. These include phosphate or organic ester fluids and blends, water-glycol solutions and water-oil invert emulsions.
M3B AND M4* SERIES MOTORS
The M3B and M4* have been designed especially for severe duty applications which require high pressure up to 3400 PSI, high speed up to 4000 RPM and low fluid lubricity (HF-1, HF-2A, HF-3, HF-4, HF-5).
