Sun Hydraulics' Motor Mount Manifolds Facilitate Control and Protection of Hydraulic Motors

Many users of hydraulic motors prefer to mount control and protection devices directly to the motor, reducing labor costs and eliminating potential leak points. This method additionally provides for the valve functions to be located as close as possible to the motor, resulting in improved system dynamic response.

Sun Hydraulics offers a variety of standard, off-the-shelf manifolds designed to be mounted directly to a motor, and to provide commonly used hydraulic functions such as:

Cross-port relief
Single and dual counterbalance
Brake release pressure source
Hot oil shuttle/relief
Motor speed control

Manifolds are available for both closed- and open-loop applications and are manufactured in aluminum, with an operating pressure of 3000 psi (210 bar), and ductile iron rated for 5000 psi (350 bar). Since several manufacturers have adapted identical mounting and porting patterns for similarly sized motors, Sun manifolds can be used across a wide range of hydraulic motors.

Motor mount manifolds are available for the following models of hydraulic motors and their equivalents:
