The Rineer patented vane crossing vane design produces
much higher volumetric and mechanical efficiencies than is
possible with a standard vane type design. This design
provides a sealing vane between cavities to improve
mechanical and volumetric efficiencies.

The 15 Series has four stator cavities and 10 rotor vanes.

ach rotor vane works in each stator cavity once per
revolution, which results in 40 power strokes per revolution.
This helps produce higher mechanical efficiency and flatter
torque curves.

We suggest premium grade fluids containing high quality rust,
oxidation and foam inhibitors, along with anti-wear additives.
For best performance, minimum viscosity should be
maintained at 100 SSU or higher. Fluid temperature should not
exceed 180

levated fluid temperature will adversely affect
seal life while accelerating oxidation and fluid breakdown. Fire
resistant fluids may be used with certain limitations. Contact
Rineer for additional information.

DRAIN
The 15 Series Motor is designed for either internal or external
case drain. Two case drain ports are supplied. When using
internal case drain, simply plug the two ports. When using
external case drain, use the port at the highest elevation. We
recommend case drain pressure of 35 PSI or less when using
the standard seals.

The shaft is retained in the retracted position by inserting a
