Sludge reflux pumpThis pump is a self-developed product based on the production technology of German submersible motors. It is a specialized equipment for mixed liquid reflux, denitrification and denitrification in secondary sewage treatment plants. It can also be used in ground drainage, irrigation and wastewater treatment processes that require micro head and high flow rate for recycling.

The sludge reflux pump is specially designed for micro head and high flow rate, with high efficiency; Specially designed for anti clogging and anti winding, reliable in use; By using the latest sealing materials, the pump can operate safely and continuously for over 10000 hours; Compact structure, easy installation and maintenance; The host adopts a stamping structure, with small size, high precision, corrosion resistance, and no noise. The stainless steel sludge reflux pump product is equipped with protection and alarm devices for leakage, water leakage, and motor overload to ensure the safety and reliability of the product.

Proper installation and use are the basic guarantees for the long-term and normal operation of stainless steel sludge reflux pumps. Users are reminded not to be careless. An automatic coupling installation system is adopted, which can quickly lift the pump for inspection without any mechanical disassembly, making it convenient and fast. This device has applied for a national patent.Stainless steel sludge reflux pumpIn addition to pre embedded wall pipes, guide rods and lifting rods are connected to the wall with expansion bolts without the need for pre embedded parts. This is a new product developed based on the production technology of submersible mixers. The pump is a specialized equipment for mixed liquid reflux and denitrification in secondary sewage treatment plants, and can also be used for pumping purified water during ground drainage; Irrigation and control of waterway systems; Micro head and high flow areas are required in the recycling or mud suction circuits during wastewater treatment.

The stainless steel sludge reflux pump is specially designed for micro head and high flow rate, with high efficiency, resistance to blockage and entanglement, reliable use, and the use of the latest sealing materials. It can operate safely and continuously for more than 10000 hours. The structure is compact, easy to install and maintain, and the main body adopts a stamping structure, with small volume, high precision, corrosion resistance and no noise. It is equipped with leakage and motor overload protection (alarm) devices to ensure product safety and reliability. The specially designed device components and equipment spare parts of the stainless steel sludge reflux pump enable the sludge reflux pump to achieve optimal performance.

Structural design of sludge reflux pump

Specially designed device components and equipment spare parts enable the sludge reflux pump to achieve optimal performance.
1. Cable: The cable adopts a specially designed waterproof cable;
2. Junction box: The junction box is fully 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: Imported bearings are used, with a designed service life of 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, efficient and unobstructed operation, and have self-cleaning function;
9. Imported cone tube: The purpose of imported cone tube is to form the best flow state;
10. Discharge joint: The discharge joint is used to fix the inlet cone pipe on the outlet pipe;
11. Guiding device: The guiding device consists of two pipes (conduits) and an upper conduit clamp.

Installation characteristics of QJB-W1.5/8 stainless steel sludge reflux pump

1. Proper installation and use are the basic guarantees for the long-term and normal operation of this pump.
