Shaft seals are generally designed for pressure-free operation. For applications requiring increased pressures, the use of high-pressure shaft seals is recommended. With optimised lip geometries (short but flexible sealing lip, thicker rubber membrane, metal cage closer to the shaft), our high-pressure shaft seals can resist up to 1.5 MPa of pressure.
The DCHP profile is a high-pressure shaft seal composed of a single metal cage and a rubber coating, and a double primary sealing lip with integrated springs to separate fluids.
SCHP
The SCHP profile is a high-pressure shaft seal composed of a single metal cage with a rubber coating and a primary sealing lip with an integrated spring.
DCWHP
The DCWHP profile is a high-pressure shaft seal composed of a single metal cage with rubber grooves on the outside of the cage and a double primary sealing lip with integrated springs to separate fluids.
TCWHP
The TCWHP profile is a high-pressure shaft seal composed of a single metal cage with rubber grooves on the outside of the cage and a primary sealing lip with an integrated spring and an additional anti-pollution sealing lip.
TCHP
Very good static sealing Very good thermal expansion compensation Greater roughness is allowed in the housing Reduced risk of corrosion Sealing for low and high viscosity fluids Primary sealing lip designed for higher pressures up to 1 MPa Protection against undesirable air contaminants
