The 150QJ series Deep Well Submersible Pump is a high-performance lifting solution engineered for direct connection between the submersible motor and the pump unit. Featuring a vertical, compact structure with a small footprint, this series is designed for seamless installation and simplified maintenance. It serves as an essential piece of equipment for agricultural irrigation, municipal engineering, urban water supply, and industrial mining operations, offering exceptional reliability in disaster relief drainage and diverse water conservancy projects.

Engineered for precision and durability, the 150QJ series delivers a versatile flow range from 5 to 500m³/h and a significant head lift of up to 800m, powered by motors ranging from 3 to 315KW. With a robust water-sealed wet submersible design, the motor utilizes clean water for both cooling and bearing lubrication, ensuring stable performance even in demanding environments. This combination of powerful lifting capacity and structural integrity makes it the premier choice for professional deep-well water extraction.

Frequently Asked Questions

Q: What are the optimal water quality conditions for the 150QJ pump?

The pump is designed for clean water with a pH value between 6.5 and 8.5, water temperature not exceeding 20°C, and solid impurities content not greater than 0.01% by mass ratio.

Q: How should the motor be prepared before the first installation?

The motor cavity must be completely filled with clean, non-corrosive water to lubricate rubber bearings and cool the motor. Ensure the water screw is tightened and insulation resistance is measured after 12 hours.

Q: Can the 150QJ pump be used for muddy water or new wells?

No, this is a clean water pump. Pumping sediment or muddy water from new wells is strictly prohibited as it will cause premature wear and damage to the impellers and bearings.

Q: What is the minimum distance the pump should be from the well bottom?

To avoid sucking in mud or sand, the distance from the bottom of the pump to the bottom of the well should generally be no less than 3 meters.

Q: How do I protect the pump during winter storage?

To prevent the motor cavity from freezing and cracking, all water must be drained from the motor before storage in a room with temperatures below freezing.

Q: What are the common wearing parts that need replacement?

Common wearing parts include the impeller, shaft sleeve, rubber shaft sleeve, and sealing rings. We recommend a full maintenance check every year of operation.
