The 150QJB Deep Well Submersible Pump is a high-performance industrial solution engineered for precision water extraction. Featuring advanced frequency conversion winding with specialized water-resistant wire, this pump is designed to withstand high-frequency stamping and pulse peak voltages. The intelligent frequency conversion design allows the motor to operate stably between 1Hz and 50Hz, significantly enhancing energy efficiency and extending the overall service life of the equipment.
Built for versatility and durability, the pump employs a water-filled wet structure to ensure optimal cooling and lubrication of the bearings. With a robust construction that includes a sand-prevention ring and high-quality insulation, it is perfectly suited for demanding environments such as agricultural irrigation, high-rise water supply, and deep-well water intake, delivering consistent flow rates and high-head pressure across various operational depths.

Frequently Asked Questions
It is ideally suited for deep well water intake, agricultural and garden irrigation, high-rise building water supply, river water intake, and general domestic water solutions.
It allows the motor to operate stably between 1Hz and 50Hz, which reduces energy consumption and protects the motor against voltage pulses and high-temperature aging.
While designed with sand rings and oil seals to protect the motor, it is strictly prohibited to pump sediment or turbid water in new wells to avoid premature damage.
The pump should be completely immersed in water with a maximum penetration depth of 70m, and it must maintain a minimum distance of 3m from the bottom of the well.
We recommend pulling the pump for disassembly and maintenance every year of operation, or if the diving time has reached two years, to replace worn impellers and seals.
All water must be drained from the motor cavity to prevent freeze damage. The pump should be stored indoors in a non-corrosive environment below 40°C.
