Abstract: In one aspect, there is provided a wear plate for use in combination with a centrifugal pump and impeller. The wear plate has a wear surface defined by a substantially flat surface, a truncated conic section, and/or a curvilinear solid of revolution formed by revolving an area bounded by a curve around a center axis of the wear plate, wherein a notch or recess is provided. The notch or recess extends in a first direction perpendicular to a predetermined direction of rotation of an impeller and a second direction crossing against a direction of rotation of the impeller.

Abstract: A booster station having an integral foundation preinstalled prior to shipment to an installation site. An above ground pump enclosure houses at least one pump. Each pump has a pump inlet for receiving water and a pump outlet for discharging water at a predetermined pressure. A relatively rigid concrete foundation is integral to the pump enclosure. The foundation has an inner wall surface forming a chamber, an outer wall surface, a top wall supporting the pump enclosure, and a foundation floor opposite the top wall having an opening therein for allowing drainage of fluid from the chamber. The foundation has at least one inlet port for receiving water and at least one outlet port for discharging water to a water transport system. The inlet and outlet pipes are connected to the foundation ports at a first end and to the purrip at a second end. The inlet and outlet pipes include a relatively flexible synthetic rubber boot located at the first end that extends through the foundation outer wall surface.
