Product Introduction

The QJB-W submersible reflux pump, also known as the reflux through wall pump, is a specialized equipment for denitrification and denitrification in sewage treatment plants. It can also be used in low head, high flow areas such as ground drainage, irrigation, and wastewater treatment processes that require low head and high flow.

The equipment can operate continuously and normally under the following conditions:

During continuous operation, the temperature of the medium should not exceed 40 ℃

The pH value of the medium is 5-9

Long term diving operation, with a maximum submergence depth of 10m

The reflux pump must operate completely submerged in water and cannot work in flammable, explosive, and highly corrosive environments.

Performance characteristics of submersible reflux pump:

1. Micro head, high flow rate, high efficiency

2. Using the latest sealing materials, two mechanical seals made of tungsten carbide/silicon carbide, imported bearings, and all fasteners made of stainless steel, the pump can operate safely and continuously for more than 10000 hours.

3. The impeller has a good hydraulic design structure, and the swept back blades have self-cleaning function, anti clogging, and anti winding.

4. Compact structure, simple operation and maintenance, easy installation and maintenance, long service life.

The host adopts a casting or stainless steel stamping structure, with small volume, high precision, corrosion resistance, and no noise.

5. The insulation level of the motor winding is F, and the protection level is IP68

6. The product is equipped with protection and alarm devices for leakage, motor overload, etc., to ensure the safety and reliability of the product.
