QZ type submersible axial flow pump Overview: QZ series submersible axial flow pump is the replacement of the traditional water pump - motor unit. Applicable to industrial and mining, dock, urban water supply, drainage and sewage works, as well as flood control works. Used for conveying clean water under 40℃ or other liquids with physical and chemical properties similar to water. This type of pump is a high flow, low head pump. Range of parameters: flow Q 0.18 ~ 10m3/s head H 1 ~ 13m Model Description: 20QZJ -- 2.1 -- Pump outlet diameter of 20 inches (500mm) QZ -- submersible axial flow pump J -- pump speed change mark 2.1 -- Design head 2.1m structure: the motor driving the pump is dry fully enclosed submersible three-phase asynchronous motor. The submersible electric pump can run under water for a long time and has a series of advantages that the traditional unit cannot compare with. The submersible motor of the submersible pump is placed above the pump. The submersible motor is of dry structure, F class insulation, reliable mechanical seal and auxiliary seal, and has leakage and internal winding temperature rise protection device. The impeller blade of the pump is semi-adjustable. The user can adjust the blade Angle according to requirements to meet the requirements of changing working conditions. A water-lubricated bearing is set near the upper end of the impeller to reduce the extended length of the blade shaft end and improve its stability. Direction of rotation: The pump rotates clockwise from the motor end. Main parts: cast iron range: pump, motor, control cabinet and necessary accessories. When ordering, please indicate the material of main parts, if you have special requirements for pumps and motors, you can negotiate with our company about the technical requirements.
