200QJX20-600/30 Bottom Suction Submersible Pump 
Example: 200QJX20-600/30

200 indicates the applicable well diameter is not less than 200 mm. Q stands for submersible (initial letters of Chinese Pinyin); J stands for well use (initial letters of Chinese Pinyin); X indicates bottom suction (initial letters of Chinese Pinyin): 20 means the flow rate is 20 m³/h; 600 means the head is 600 meters; /30 indicates 30 stages of impellers in series.
Zhijiang Brand 200QJX20-600/30 Bottom Suction Submersible Pump  is a new type of water lifting machinery carefully 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 water supply systems, and various regional secondary water supply systems. The QJX bottom suction pump adopts an integrated design with a robust structure, simple installation and maintenance, and stable operation; high mechanical efficiency and low operating costs. The motor uses a dynamic water jacket for cooling, providing 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.

Zhijiang Brand 200QJX20-600/30 Bottom Suction Submersible Pump Motor Parameters

The submersible motor is lubricated by clean water. Before use, the motor cavity must be filled with clean water (Note: It must be filled completely; otherwise, the motor's service life will be reduced). If water is forgotten, the motor will burn out quickly.

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 reduces the overall unit height and increases operational stability. The pump shaft diameter is φ38mm, enhancing the shaft's torsional resistance. The shaft bush is made of natural rubber material for better wear resistance and is equipped with a hard shaft bush made of imported material (with an added metal outer protective sleeve, a special product).
