Equipment Nickname
Nitration liquid recirculation pump, mixed liquid recirculation pump, QJB-W type recirculation pump, horizontal propeller pump, high flow low head pump, sludge recirculation pump, internal recirculation pump, wall penetration pump
Product Introduction
Product Application Range:
The QJB-W type sludge recirculation pump is an improved product based on the submerged mixer production technology. It is used for the mixing liquid recirculation and denitrification in secondary wastewater treatment plants, and can also be used for pumping purified water during ground drainage; irrigation and control of waterways; and in the recycling process or sludge extraction circuit during wastewater treatment where low head and high flow rates are required.
Terms of Use:
1. During continuous operation, the medium temperature does not exceed 40°C.
2. Medium pH level is 6-9.
3. Maximum Submersion Depth: 10m.
Model Representation Method:
Structure Overview:
Equipment and spare parts ensure optimal performance of the sludge recycle pump.
1. Cable: The cable is made of a specially designed 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. Shaft: The motor shaft is made of stainless steel and undergoes dynamic balance testing for the rotor.
5. Sealing: Static sealing is achieved with an O-ring. Axial sealing is mechanical, isolating the oil chamber from surrounding media.
6、Oil chamber: The oil is used for lubricating and cooling the mechanical sealing friction pair, as well as for isolating the渗透液 (penetrating fluid).
7. Impeller: The impeller features three blades, which are wide and thin with a smooth, swept-back surface for unobstructed rotation and have an automatic self-cleaning function.
8. Imported Conical Tubes: The purpose of imported conical tubes is to achieve a better flow state.
9. Discharge Connector: The discharge connector is used to secure the imported tapered pipe to the outlet pipe.
10. Guiding Device: The guiding device consists of two tubes (conduits) and a top tube clamp.
Product Features:
1. Designed for low head and high flow.
2. Resistant to clogging and entanglement, reliable in use.
3Compact structure, easy installation and maintenance.
4. The main unit features a stamping formed structure, with a small size, high precision, corrosion resistance, and no noise.
5. Equipped with leakage, water leakage, and motor overload protection (alarm) devices to ensure product safety and reliability.

Installation:
Proper installation and use are fundamental guarantees for the long and normal operation of this pump.
2. The sludge recycle pump is equipped with an automatic coupling installation system, allowing for quick equipment inspection and maintenance without any mechanical disassembly, ensuring easy and fast installation.
3. This equipment requires pre-burial only for the wall penetration pipe. The guide rods and lifting frames are connected to the pool body using steel expansion bolts, no pre-buried parts are needed.
4. Pre-installed components and flap gates are procured and installed by the customer. Attention should be paid to this during ordering.
