High Hydraulic Efficiency Submersible Pump

Submersible pumps are integrated electromechanical underwater operating devices consisting of a submersible motor and a pump. The entire unit is submerged in water during operation, featuring compact size, convenient installation, quiet operation, and high efficiency. Requiring no priming, they offer easy startup and are widely used in applications including farmland irrigation, urban water supply and drainage, groundwater extraction, sewage lifting, and industrial cooling. They are essential equipment for the efficient transportation of clean water, sewage, or liquids containing sand. Depending on the application, submersible pumps are categorized into sewage pumps, deep well pumps and other types to accommodate different working media and operating environments.

SJ Multistage Deep Well Submersible Pump

The SJ multistage deep well submersible pump is paired with a submersible motor, replacing the traditional long-shaft connected deep well pump configuration. The pump body is equipped with a built-in check valve, effectively preventing backflow during shutdown. This reduces the impact of water hammer on the pump, enhancing the reliability and stability of the system.

Flow rate: 0.2 m³/h – 260 m³/h
Head: 4 m – 381 m
Temperature: Max. +25 °C
Voltage: 220V/380V
Material: Stainless steel
