Tianjin Zhijiang Pump Industry Down-Suction Submersible Pump:

The QJX series down-suction submersible 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; the construction or renovation of urban tap water systems, and various regional secondary water supply systems. The QJX down-suction pump adopts an integrated design, featuring a robust overall structure, simple installation and maintenance, and stable operation. It boasts high mechanical efficiency, significant energy-saving effects, and low operating costs. The motor utilizes dynamic water jacket cooling, providing excellent heat dissipation conditions and effectively extending the motor's service life. There is no need to build a pump room or fixed lifting equipment, greatly reducing the investment in civil engineering and supporting equipment for the water supply system. The equipment operates submerged, producing no noise, water leakage, or oil leakage, causing no environmental pollution, and is 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 for down-suction submersible pumps, the company has strong technical expertise, timely supply, and energy-saving and environmental protection features. The Zhijiang brand down-suction submersible pump has been used for years with excellent results and stable operation.

Down-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.
Motor protection level: IPX8
Power supply
380V/50HZ, 660V/50HZ. If customers require special voltage or frequency, please inform us in advance.
Materials: Special materials and special requirements require customization.
Impeller: Cast iron HT200, or tin bronze (various grades) such as: ZCuSn3Zn8Pb6Ni1
Pump casing: Cast iron HT200, or stainless steel such as: 2Gr13, 304, 316, 316L, 2205 duplex stainless steel, etc.
Pump shaft: Stainless steel 2Gr13 (tempered at 1050°C to enhance torque)
Motor seal: Rubber seal O-ring; skeleton oil seal/mechanical seal.
Motor expansion adjustment bladder made of rubber material.
Equipment Advantages
--Careful assembly in the factory ensures quick and reliable on-site installation.
--Multi-stage impeller design results in extremely low noise.
--Built-in check valve prevents water hammer impact.
--High single-stage head reduces the overall unit height and increases operational stability. The pump shaft diameter of φ38mm enhances the shaft's torsional resistance. The shaft bush is made of pure 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).
