<p>PURPOSE:To substantially reduce noises with light simple constitution by molding integrally a suction path and discharge path on a pump base made of synthetic resin and attaching a pump cover for enclosing the whole parts installed on the upper surface of the pump base to the pump base. CONSTITUTION:The pump is provided with a pump body section, an inner suction pipe 10 communicating to the suction side of the pump body section, an inner discharge pipe 22 communicating to the discharge side of the pump body section and a pump base 1 made of synthetic resin to install the pump body section, inner section pipe 10 and inner discharge pipe 22 on its upper surface. A water suction path 9 having its one end opened to the side of the pump base and the other end communicating to the inner section pipe 10 and a water discharge path 21 having its one end opened to the side of the pump base 1 and the other end communicating to the inner discharge pipe 22 are integrally molded on the pump base 1 while a pump cover 29 for enclosing the whole parts such as the pump body section, etc., to be installed on the upper surface of the pump base 1 is constituted to be attached to the pump base 1.</p> |
