Claron Polyseal Single Acting Rod Seal CPUI/OR

Design:

Claron style CPUI…/OR is a Polyurethane U-seal incorporating an O-Ring energiser. This guarantees the pre-loading of the seal lips for low pressure sealing, thus optimising seal performance. Polyurethane provides outstanding abrasion and wear resistance ensuring that the seal operates in the most arduous conditions. The anti-extrusion ring which is energised at high pressures, increases the maximum working pressure as well as protecting the seal against pressure spikes.

These range perameters are Maximum simultaneous conditions.

Optimum service conditions are affected by temperature, speed, pressure, surface finish and extrusion gaps.

Refer to Appendix 1 for further information.

Note: Clearance gap F is the maximum permissable. i.e. gap completely on one side, in the temperature range of -30°C to 80°C The use of a suitably selected Claron bearing ring will effectively reduce the clearance gap F max. to a value closer to F/2 thus increasing the pressure capability of the seal.

Housing:

For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machining tolerances refer to the catalogue page of selected seal. Refer to Appendix 4 for value of tolerance symbols.

Fitting:

For the seal to function correctly, it is important that care be taken in fitting the seal within its housing. For a detailed checklist, refer to Appendix 3.
