ZW type coupling type unobstructed self-priming pump - Product Overview

ZW type coupling typeNon clogging self-priming pumpOur company's designers are based on the ZX modelSelf priming centrifugal pumpThe structure and performance of the QW type sewage pump, drawing on the advantages of similar products at home and abroad, and absorbing the usage requirements and opinions of users from various aspects, has been developed into a self suction and sewage discharge device. It can not only be used without a bottom valve or water injection like a general clean water self suction pump, but also suck up pollutants, sediments, waste mineral impurities, feces treatment, and all engineering sewage and glial liquids containing large solid particles with a diameter of 60% of the outlet diameter and a fiber length of 1.5 times the impeller diameter. It completely reduces the labor intensity of workers, and is easy to use, move, and install with minimal maintenance and stable performance.

ZW type coupling type unobstructed self-priming pump - model meaning

ZW type coupling type unobstructed self-priming pump - product advantages

1. Strong sewage discharge capacity: The special impeller anti blocking design ensures that the pump is efficient and unobstructed.

2. Efficient and energy-saving: adopting excellent hydraulic models, with efficiency higher than averageself-priming pump3-5% higher.

3. Good self-priming performance: The self-priming height is 1 meter higher than that of a typical self-priming pump, and the self-priming time is shorter.

ZW type coupling type unobstructed self-priming pump - working principle

ZW typeSelf suction unobstructed sewage pumpIt mainly consists of a pump body, impeller, back cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water inlet valve, inlet and outlet pipes, etc. The structure of the pump is shown in the diagram. ZW typeSelf suction sewage pumpWorking principle: The pump body is equipped with a liquid storage chamber, which is connected to the pump working chamber through the upper reflux hole and the lower circulation hole, forming an axial flow external mixing system of the pump. After the pump stops working, there is already a certain volume of liquid stored in the pump chamber. When the pump is started, the liquid stored in the relevant authorities is ejected upwards with air under the action of the impeller. The liquid flows back to the working chamber through the grid of the gas-liquid separation tube, and the gas is discharged outside the pump, creating a certain degree of vacuum inside the pump and achieving self-priming.
