S Series

S Series

The actuating cylinder and piston in the S series design do not rotate. They are bearing sup-ported on the mounting hub and are held stationary by the external connection to the inlet port. This bearing allows the separator discs and hub, and the shaft on which it mounts, to rotate about the cylinder and piston. A thrust bearing permits relative motion between the stationary piston and rotating separator discs. Because both bearings require lubrication, it is important to utilize lube ports provided and/or direct an oil spray or splash at bearing surfaces.

Marine Applications

P Series

The P series design is similar to the S series, which is designed for wet operation. The difference between the two models occurs in the bearings. P Series bearings are pre-lubricated and sealed and do not require external lubrication. Torque ratings are based on the P Series disc pack operating in dry conditions thus requiring lower actuation pressure to achieve relatively high rates of torque.

R Series

R Series

The R series design provides maximum torque within a small envelope. In the R Series design, the piston and actuating cylinder, which is integral with the mounting hub, rotate. Bearings are not required. The shaft on which the hub mounts is rifled and cross drilled to provide passage for the actuating media. A press fit or cap seals are necessary to prevent media pressure loss due to seepage past the hub and shaft interface.
