The Planet Fixed Displacement Ball Piston Hydraulic Motor is built to the highest quality standards - a compact light weight, high efficiency motor that provides dependable rotary power with a broad speed range and low noise level.

This motor employs 10 ball pistons uniformly distributed and ported, reacting with precision anti-friction bearing displacement rings to provide a virtually pulseless, vibration-free output rotation at any speed. Output torque is constant throughout entire speed range, with constant input pressure. Reversibility with identical dynamic characteristics in either direction is provided by precisely identical flow paths within the motor.

The motor may be operated continuously, reversed or stalled while under full load conditions. It may also be mounted in any position. Motor can be run with or without case filled. An empty case is recommended for speeds above 2000 rpm. Operating temperature is limited by the hydraulic fluid capabilities. A 10 micron filtration ahead of the motor is recommended. Filtration to this degree will prolong motor life and efficiency.
