Frequently Asked Questions

Q: What is the maximum immersion depth for the 200QJB pump?

The pump is designed for a maximum immersion depth of 70 meters. It must be installed vertically and kept at least 3 meters above the well bottom.

Q: Can this pump handle muddy or sandy water?

This pump is designed for clean water. It is strictly prohibited to discharge sediment or mud during new well drilling, as this can damage the impeller and bearings.

Q: How does the variable frequency winding benefit the user?

It allows the motor to operate stably between 1Hz and 50Hz, which reduces energy consumption and prolongs the product's service life through optimized power usage.

Q: What electrical protection is required for installation?

The pump must be equipped with a distribution box providing short-circuit overload, phase loss, undervoltage, grounding, and idling protection.

Q: Is the motor cooling system internal or external?

The motor uses a water-filled wet structure where the cavity is filled with clean water to both cool the motor and lubricate the bearings.

Q: What should I do if the pump is stored in freezing temperatures?

Water must be drained from the motor cavity during winter to prevent freezing, which could otherwise damage the motor body.
