Zhijiang Brand Vertical Large-Diameter Non-Clogging Mixed Flow Pump

For example; 1400QHB-50

ZJ represents the enterprise's upgraded model; 1400 indicates the nominal outlet diameter of the pump is 1400mm; Q stands for submersible (the initial letters of the Chinese Pinyin); Z represents axial flow pump; B denotes semi-adjustable blades; 50 indicates the specific speed code of the pump, which is the specific speed divided by 10.

Principle of Zhijiang Brand Vertical Large-Diameter Non-Clogging Mixed Flow Pump

The QZB type axial flow submersible pump and QHB mixed flow submersible pump are upgraded products of traditional pump-motor units. The motor driving the pump is a dry, fully enclosed submersible three-phase asynchronous motor. This type of submersible electric pump can operate submerged in water for extended periods.

Zhijiang Brand Vertical Large-Diameter Non-Clogging Mixed Flow Pump offers better advantages compared to traditional units.

(1) Since the motor and pump are integrated, on-site installation is convenient and fast, saving up to 95% of installation time compared to traditional units.

(2) As the motor operates submerged, it has excellent cooling conditions. The pump station remains free of high temperatures and low noise, allowing for the construction of underground pump stations that preserve the ground environment. This greatly simplifies the geotechnical and structural engineering of the pump station, reduces the installation area, and saves 30-40% on construction costs.

(3) The submersible motor adopts double or triple mechanical seals and auxiliary sealing structures, with F-class insulation resistant to temperatures up to 155°C, and a protection rating of IP68. Additionally, the motor is equipped with detection devices for seal leakage, winding, and bearing temperature rise.

(4) Detection signals are centrally fed back to the monitor in the electric control cabinet, making operation convenient and easy to achieve automatic and remote control.

It can be widely used in industrial and mining ships, urban water supply and drainage, farmland irrigation and drainage, and power station water supply and drainage. The QZB axial flow submersible electric pump is suitable for low-head, high-flow scenarios. The aforementioned products transport media such as raw water or mildly polluted water, with a maximum liquid temperature of 50°C, a pH value of 4–10, a volumetric ratio of transported media below 2%, and a media density less than 1.2×10³ kg/m³. Using this product is an ideal solution for addressing the flood prevention issues of motors in pump stations built in areas along rivers and lakes with significant water level fluctuations.
