The 28 mm diameter mechanical shaft seal is a complete sealing assembly designed for Karpa and Kapri counter-current pumps, preventing water from penetrating from the spiral housing onto the bearings and motor.
The kit contains all the necessary seal components – ceramic ring, rubber sleeve and spring – so the replacement is complete and trouble-free.
Water leaks in the area of the pump shaft are a clear sign of seal wear and require prompt action to prevent damage to the electric motor.
The 28 mm diameter corresponds to the standard shaft of the Karpa/Kapri series and ensures a precise fit and long-term tightness even under pressure in the hydraulic circuit.
