Feili stainless steel submersible reflux pump through wall pump - sludge pump

Feili stainless steel submersible reflux pump through wall pumpPurpose:

The QJB-W submersible sludge reflux pump is a product based on the production technology of submersible motors. This pump is an equipment for mixed liquid reflux and denitrification denitrification in secondary sewage treatment plants. It can also be used in places where micro lift and high flow are required for surface drainage, irrigation, and wastewater treatment processes such as recycling.

Conditions for use of submersible reflux pump:

During continuous operation, the medium temperature should not exceed 50 ℃ and the altitude should not exceed 2000m.

The pH value of the medium is 5-9.

The submergence depth shall not exceed 10m.

Feili stainless steel submersible reflux pump through wall pumpPerformance characteristics:

Micro head, high flow rate

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

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

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

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

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

The product is equipped with protection and alarm devices such as leakage and motor overload to ensure the feasibility of the product.

Structure Introduction:

Specially designed device components and equipment spare parts enable the sludge reflux pump to achieve good performance.

1. Cable: The cable adopts a waterproof cable;

2. Junction box: The junction box is completely enclosed and isolated from the surrounding liquid and stator box;

3. Motor: 50Hz squirrel cage 3-phase submersible asynchronous motor, F-class insulation, protection level IP68. The motor is cooled by the surrounding medium;

4. Shaft: The shaft of the electric motor is made of stainless steel material, and the rotor undergoes dynamic balance testing;

5. Sealing: The static seal is an O-ring seal. The shaft seal is a mechanical seal that isolates the oil chamber from the surrounding medium;

6. Bearing: Using branded bearings, the designed service life can reach over 100000 hours;

7. Oil chamber: Oil is used to lubricate and cool the mechanical seal friction pair, and isolate the permeate;

8. Impeller: The impeller has three blades, which are wide and thin, with a smooth and swept back surface, and high Efficient and unobstructed operation, with self-cleaning function;

9. Cone tube: The purpose of a cone tube is to form a good flow state;

10. Discharge joint: The discharge joint is used to fix the cone tube on the outlet pipe;

11. Guiding device: The guiding device consists of two pipes (conduits) and an upper conduit clamp.
