High head and large flow QJ cast iron submersible pump
energy-saving and efficient
High head and large flow QJ cast iron submersible pump Product Overview
The QJ series deep well submersible pumps are our independently
developed, high-efficiency, energy-saving submersible pumps,
designed specifically for high-lift, high-flow applications.
Crafted from cast iron and incorporating advanced hydraulic
modeling and sealing technologies, these pumps are suitable for a
variety of applications, including deep well water extraction,
agricultural irrigation, urban water supply, and industrial
drainage. Their compact, integrated design (directly coupled pump
and motor) allows for direct submersion, eliminating the need for a
pump room, saving space, and facilitating easy installation and
maintenance. They are ideal for modern agriculture, industry, and
municipal projects.
High head and large flow QJ cast iron submersible pump Core Advantages
High head, high flow, and excellent performance
Head range: 10-800 meters, flow range: 10-2400 m³/h, meeting
complex requirements such as deep well water extraction and
high-rise water supply.
The multi-stage vertical centrifugal pump design delivers high head
per stage, low axial force, stable operation, and 15%-20% higher
efficiency.
Energy-saving, efficient, economical, and environmentally friendly
Using oxygen-free copper bar rotors and water-lubricated bearings,
these pumps reduce energy consumption, offer a strong motor
overload capacity, and deliver significant energy savings. Complies
with national energy efficiency standards, saving electricity costs
through long-term operation.
Sturdy, durable, and highly adaptable.
The cast iron pump body is corrosion-resistant and wear-resistant,
suitable for clean water environments with a sand content of ≤
0.01%.
It can be installed as long as the well wall is straight and
smooth, and is compatible with various well types, including steel
pipe wells, ash pipe wells, and earth wells.
Intelligent protection, safe and reliable.
The quadruple sand filtration system effectively reduces wear on
the motor caused by sand in the water, extending its service life.
Built-in check and non-return valves prevent water hammer during
shutdown and protect the unit.
Easy installation and worry-free maintenance.
Flange connection to the water supply pipe, equipped with gate and
throttle valves, provides flexible operation. The cable outlet seal
design provides excellent waterproof performance.
Tool-free quick assembly and disassembly reduces maintenance costs.
