Frequently Asked Questions

Q: What are the ideal water quality requirements for this submersible pump?

The pump is designed for clean water with a temperature ≤ 20°C, PH value between 6.5-8.5, and solid impurities content no greater than 0.01% by mass.

Q: Can the 175QJB pump be installed horizontally?

No, the submersible pump must be installed strictly vertically. Horizontal or inverted installation is strictly prohibited to avoid motor damage.

Q: How does the frequency conversion design benefit the user?

It allows the motor to operate smoothly between 1Hz and 50Hz, providing greater energy savings and extending the service life of the pump.

Q: What precautions should be taken before starting the pump?

The motor cavity must be completely filled with clean, non-corrosive water to lubricate bearings and cool the motor. Ensure the pump is fully immersed in water.

Q: What are the typical application scenarios for this pump?

Typical applications include deep well water intake, high-rise building water supply, agricultural and garden irrigation, and river water intake.

Q: How often should the pump be maintained?

It is recommended to take the pump out for dismantling and maintenance after one year of operation or once every two years of diving time to replace worn parts.
