Ebsray Pumps – part of PSG, a Dover company – introduced a new mechanical-seal assembly for its RC Series regenerative turbine pumps. This new seal assembly is a direct replacement for the existing seal assembly on the RC20, RC25 and RC40 pump models, with no other part changes required. The construction of the new seal assembly uses the pump’s existing cartridge but incorporates a new multi-spring design, a silicon carbide stationary face, a carbon rotating face and FKM O-ring elastomers rated for use in temperatures as low as minus 40 degrees F (minus 40 degrees C). This new construction improves the seal’s ability to handle extreme operating conditions, perform more reliably during dry-run operation and reduce emissions under normal operating conditions, according to the company. This seal upgrade also keeps the RC Series pumps in compliance with UL51, ATEX and AS1596 operating codes.
