Product Overview: JET type self-priming jet pump (hereinafter referred to as pump) by the motor, seals, pumps of three parts. Motor is a single-phase asynchronous motor, pump part centrifugal impeller. Radial vanes structure. Between pump and motor with a single mechanical seal, seal the mouth using a fixed stop "O" shaped rubber oil seals for static sealing. Purpose: This series of pumps introduction of foreign advanced technology developed, the use of water jet principle, to achieve self-priming function and size adjustable flow, high head, high suction lift is ideal for deep water pumping equipment and submersible screw pump, compared with a long life safe, reliable, easy maintenance features, is the ideal place for the drainage device. Conditions of Use: Pump in the following conditions can be continuously work properly: 1, the working medium is non-corrosive water, medium sand content of the volume ratio of not more than 0.10%, particle size not greater than 0.20mm; 2, medium temperature does not exceed 40 degrees Celsius, the medium PH value 6.5 ~ 8.5;
