SAI distributors provide ideal functionality and reliable performance. Optimal distribution is achieved
with short ducts that have wide diameters. This reduces power loss when high flow rates are present
and achieves very high volumetric efficiency. They can also be optimized for low flow rates. Precision
machining and high performance seals provide optimal functionality though the life of the motor
as well as protecting against thermal shock. Many distributors are interchangeable, providing a
wide range of pressure ratings, port sizes, and flow control options. SAI distributors offer many
different models and a variety of solutions for any application. Please consult with the SAI technical
department to help determine the correct distributor for your application.

SAI Distributors are designed to be bidirectional. Distributors are marked with ports labelled “A” and “B”.
Both ports can be used as either intake or discharge ports. The port used will determine the rotation of
the attached motor.
For applications with frequent pressure peaks or severe vibrations, distributors with a steel anti-extrusion
ring for the main seal are recommended, and is available upon request.
Special distributors can be supplied that ensure silent running over a wide range of pressures and speeds.
*Adequate protection should be provided to protect the hydraulic charge pump
