摘要： A liquid pressure tank having particular use in a water supply system. An impervious, flexible bag or diaphragm is disposed within the tank and the interior of the bag defines a water chamber while the space between the outer surface of the bag constitutes an air chamber. The lower end of the tank is provided with an opening and the neck of the bag is formed with an enlarged bead that is sealed between a V-shaped recess formed in the flange of the tank bordering the opening and the peripheral edge of an adapter by a clamping ring. The adapter is provided with a series of holes through which water is introduced and withdrawn from the interior of the bag.

摘要： A pump construction having a housing composed of a pair of plastic housing sections. The abutting ends of the housing sections are provided with mating flanges which are joined together by a clamping ring to provide a continuous peripheral connection for the housing sections. To compensate for deflection in the plastic housing sections under operating pressure, a sliding axial connection is provided between the inlet of the diffuser of the pump and one of the housing sections. Heat is dissipated from the area of the drive shaft seal by means of a metallic shield having a base secured to one of the plastic housing sections, and the body of the shield extends outwardly within the pumping chamber in spaced relation to the seal and to the housing section.
