Product Application Range:

The QJB-W type sludge recirculation pump is a new product developed based on submersible mixer production technology. It is a specialized equipment for wastewater treatment plant mixed liquid recirculation and denitrification, and can also be used for pumping purified water during ground drainage; irrigation and waterway control systems; and low head, high flow applications in the recirculation or sludge suction circuit during wastewater treatment.

Terms of Use:

During continuous operation, the medium temperature does not exceed 40℃.

2. Medium pH value is 6-9.

3. Submersion depth is 10 meters.

Model Representation Method:

Structure Overview:

Specially designed components and equipment spares ensure optimal performance for the sludge recycle pump.

1. Cable: The cable is made with a watertight cable.

2. Terminal Box: The terminal box is fully enclosed and isolated from the surrounding liquids and the stator box.

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

4. Shafts: The motor shaft is made of stainless steel and the rotor undergoes dynamic balancing tests.

5. Sealing: Static sealing is achieved with an O-ring. Shaft sealing is mechanical, isolating the oil chamber from surrounding media.

6. Bearings: Brand-name bearings used, with a design life exceeding 100,000 hours.

7. Oil chamber: The oil is used for lubricating and cooling the mechanical sealing friction pair, as well as for isolating the渗透液.

8. Impeller: The impeller features three wide and thin blades with a smooth, swept-back surface for high-efficiency, unobstructed operation, and it also has an automatic self-cleaning function.

9. Conical Tube: The purpose of the conical tube is to achieve a good flow state.

10. Discharge Connector: The discharge connector is used to secure the cone pipe onto the outlet pipe.

11. Guidance Device: The guidance device consists of two tubes (conduits) and an upper tube clamp.

Product Features:

1. Specifically designed for low head and high flow, offering high efficiency.

2. Resistant to clogging and entanglement, reliable in use.

3. Utilizes submersible mechanical seals for safe and continuous operation exceeding 10,000 hours.

4. Compact structure for easy installation and maintenance.

5. The main unit features a submersible mixer forming structure, which is compact, precise, corrosion-resistant, and noise-free.

6. Equipped with built-in electrical leakage, water leakage, and motor overload protection (alarm) devices to ensure product safety and reliability.

Installation:

Proper installation and use is the fundamental guarantee for the pump to operate long-term and normally.

2 The sludge recirculation pump features an automatic coupling installation system, allowing for quick removal of the equipment for inspection and maintenance without any mechanical disassembly, ensuring easy and fast installation.

3 The equipment requires pre-burial only for the wall-piercing pipe. The guide rods and lifting frames are connected to the pool using steel expansion bolts; no pre-buried parts are needed.

4 Pre-buried steel pipes and butterfly valves are to be purchased and installed by the customer. Attention should be paid during the order placement.
