Recirculating pump

QJB-WType Sludge Recirculation Pump

Product Application Range:

The QJB-W type sludge recirculation pump is a new product developed based on the submerged mixer production technology. This pump is a specialized equipment for mixed liquid recirculation and denitrification in secondary wastewater treatment plants, and can also be used for...Pump purified water during ground drainage; irrigation and waterway control systems; micro-head, high-flow requirements in wastewater treatment recycling or sludge extraction circuits.

Terms of Use:

1、During continuous operation, the medium temperature does not exceed40℃；

2、MediumPHValue for6-9。

3Submersion Depth10m。

Structure Overview:

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

1Cables: Specialized watertight cables are used for the cables.

2The junction box is fully enclosed and isolated from the surrounding liquids and the stator box.

3Electric motors:50HzMouse trap style3Submersible asynchronous motorFGrade绝缘, Protection ClassIP68The motor is cooled by the surrounding medium.

4Axle: The motor's axle is made of stainless steel and undergoes dynamic balancing tests for the rotor.

5Seal: Static sealOType seal. The shaft seal is a mechanical seal, isolating the oil chamber from the surrounding medium.

6Bearings: Utilizing imported bearings, the design lifespan can reach100，000Over 1 hour

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

8The impeller features three wide and thin blades with a smooth, swept-back surface for efficient and unobstructed operation, and also has an auto-cleaning function.

9Imported Conical Tubes: The purpose of imported conical tubes is to achieve a good flow state.

10Spigot joint: Used to secure the import cone tube onto the outlet pipe.

11Guiding Device: The guiding device consists of two tubes (conduits) and a tube clamp at the top.
