A pump that has a flexible liner located adjacent to a diaphragm. The liner provides structural support for the diaphragm. The flexible liner can slide relative to the diaphragm. This relative movement reduces the stiffness of the diaphragm/liner assembly. The diaphragm/liner assembly is therefore both flexible and strong. Additionally, the liner provides a thermal insulator for the diaphragm. The flexible liner may be constructed from a low friction material to lower the friction between the liner and a wobble plate of the pump. Lowering the friction reduces the heat generated within the pump. The structural reinforcement, thermal insulation and lower friction features of the liner increase the life of the diaphragm and the pump.

A new raw water strainer includes a body having a closed first end and an open second end and defining a chamber therebetween. The chamber has a central axis intersecting the first and second ends. An inlet is provided including an inlet passage in fluid communication with the chamber. An outlet, spaced apart from the inlet, is also provided and includes an outlet passage in fluid communication with the chamber. A cover is included which is sized and adapted to be secured to the body to close the open second end. A screen assembly having first and second sides positioned in the chamber at an angle of about 45.degree. or less relative to the central axis is located so that it is between the inlet and the outlet. A basket assembly is provided which is sized and adapted to be removably placed in the chamber and to carry the screen assembly.

Heavy duty strainer

A pump comprising a housing, a diaphragm mounted in the housing, a pumping member or members, and a drive, preferably a wobble plate drive, for driving the pumping member or members on intake and discharge strokes. The wobble plate is preferably mounted on a ball bearing and includes a snap retainer assembly to retain the bearing in place without force fitting. The wobble plate preferably defines one or more open ended chambers in which the pumping member or members are placed. The annular zone or zones of the diaphragm which flex when driven by the wobble plate drive to provide the pumping action are configured to increase efficiency and/or to reduce wear.
