MSS pumps develop pressure by accelerating fluid through a channel. Rotating this fluid through centrifugal force develops a pressure higher than was input. Pressure can be increased by lengthening the channel through the addition of impeller stages or increasing their size. Motors are selected according to equipment operating requirements (Figure 1). A flexible coupling allows the pump shaft to float within the coupling reducing thrust against the motor. The inlet and discharge housings are designed to connect to grooved rigid piping with couplings. The inlet housing itself can be attached to the pump in four different positions 90° apart. A precision leveling foot supports the end shell housing and is fully adjustable to allow accurate pump-to-motor shaft alignment.

MSS Pump Internal Components The internal components of an MSS pump can vary depending on pump configuration and number of stages. The basic components contained in a single stage consist of an impeller and a diffuser with a spacers and bushing which prevent friction and wear. Behind the discharge housing at the end of the pump is the cavity cover, balance disc and bearing carrier. (Figure 2). The balance disc rides in the bearing carrier and serves as a thrust bearing for the pump. This unique design uses patented WATER BEARING™ technology which allows feed water cool and lubricate the disc. Because the balance disc is located at the discharge end of the pump, it keeps the shaft in tension. As the motor rotates the pump, internal pressure causes the impeller stacks to compress and move away from the motor lifting the balance disc off the bearing carrier. Pressure on the front of the balance disc is stabilized by the throttle nipple which allows pressure to travel back through the drain line and into the inlet housing. This thrust and counter thrust allows the disc to "self-balance" based on operating conditions.
