PRP EZ Seal System
The PRP mechanical seal chamber spigots directly onto the standard well proven LKIT also designed and manufactured by PRP. This results in the mechanical seal now being kept concentric with run outs and tolerances well within the limits of standard mechanical seals.
Additionally, instead of using the spigot in the frame plate to locate the mechanical seal adaptor which in other designs results in significant concentricity problems when the saddle in the base corrodes, our design locates the seal adaptor using the flow restricting bush
The mechanical seal faces have also been located at a spot with minimal shaft overhang, resulting in virtually no shaft deflection at the seal faces even during the most unfavourable pump operating conditions
The shoulder on the shaft sleeve means the mechanical seal is self setting and will retain the correct working length when the impeller is adjusted against the throat bush.
As the impeller adjustment is possible without the hassle of setting dips and the like, the pump can be kept at optimum efficiency and the wear life of the wet end parts, particularly the impeller aid throat bush, can be increased.
