Q stands for submersible (initial letters of Chinese Pinyin); J stands for well use (initial letters of Chinese Pinyin); X indicates that the pump draws water from the lower part (initial letters of Chinese Pinyin): 650 indicates a flow rate of 650 m³/h; 32 indicates a head of 32 meters; /1 indicates a single-stage impeller in series.
Zhijiang Brand 450QJX650-32/1 Bottom Suction Sewage Pump is a new type of water lifting machinery meticulously developed by Tianjin Zhijiang Pump Industry. It is widely used for water extraction from rivers and lakes; mine water supply and drainage; construction or renovation of urban tap water systems, and various regional secondary water supply systems. The QJX bottom suction pump adopts an integrated design, with a robust overall structure, simple installation and maintenance, and stable operation; high mechanical efficiency and low operating costs. The motor uses a dynamic water jacket for cooling, with excellent heat dissipation conditions, effectively extending the motor's service life. There is no need to build a pump room or fixed lifting equipment, significantly reducing the investment in civil engineering and supporting equipment for the water supply system. The equipment operates submerged, with no noise, water leakage, or oil leakage, causing no environmental pollution, and it can be easily concealed to harmonize with the surrounding environment. Flow rate: 5-2000 m³/h Head: 10-1800 m.

Tianjin Zhijiang Pump Industry professionally provides various submersible pumps for special working conditions, with stable performance, especially strong technical expertise in bottom suction submersible pumps. Timely delivery, energy-saving, and environmentally friendly. Zhijiang brand bottom suction submersible pumps have been used for years with good results and stable operation.

Equipment Advantages

--Careful assembly in the factory ensures quick and reliable on-site installation

--Multi-stage impeller design, extremely low noise

--Built-in check valve to prevent water hammer impact.

--High single-stage head, which can reduce the overall unit height and increase operational stability. The pump shaft diameter is φ38mm, enhancing the shaft's torsional resistance. The shaft bush is made of natural rubber material for increased wear resistance and is equipped with a hard shaft bush made of imported material (with added metal outer protective sleeve, a specialty product).
