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.
