Aerobic tank sludge reflux pump

Aerobic tank sludge reflux pumpUsage conditions:

1: Altitude not exceeding 2000m, ambient temperature of 50 degrees Celsius, pH value of medium between 3 and 12, liquid density not exceeding 1150kg/m3, long-term diving operation, diving depth generally not exceeding 20m;

2: The pump must not be lower than the low liquid level during operation.
3: The rated voltage is 380V and the rated frequency is 50HZ. The motor can only operate normally when the deviation between the rated voltage and the rated frequency is no more than plus or minus 5%.

Aerobic tank sludge reflux pumpStructural Description：

1. Three phase squirrel cage motor, 380V three-phase 50HZ, protection level IP68, stator insulation level F, direct start.

2. Bearings - use lubricated bearings, NSK or SKF * brand, with a service life of over 40000 hours.

3. Impeller - The reflux pump is equipped with an advanced axial running three bladed impeller, which has good self-cleaning and vibration free functions. The design of the impeller can simultaneously meet the requirements of high flow rate and low head, and form a large flow rate in the axial direction.

4. Sealing - Adopting Swedish Feili submersible motor sealing technology to ensure safe and reliable sealing.

5. Sealed monitoring - When water enters the oil chamber, the humidity sensor in the probe leakage system will automatically send an alarm signal to detect it in a timely manner and prevent a second malfunction.

6. Temperature Monitoring - The motor winding adopts advanced and safe overheating protection technology. Once overheating is caused by motor overload, high medium temperature or other reasons, the temperature sensor will promptly issue an alarm signal or automatically shut down the water pump before the temperature exceeds the allowable temperature limit.

7. Automatic coupling system - The reflux pump is equipped with a single rail automatic coupling system to ensure quick installation, lifting, and maintenance.

Features of the equipment：

1. Sludge reflux pump with micro head, high flow rate, and high efficiency

2. The impeller has a well-designed hydraulic structure, and the swept back blades have self-cleaning function, anti clogging, and anti winding

3. Using sealing materials, two mechanical seals made of tungsten carbide - tungsten carbide, imported bearings, and all fasteners made of stainless steel, the pump can operate safely and continuously for more than 10000 hours

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

5. The host adopts a cast or stainless steel pressure forming structure, with small volume, high density, corrosion resistance, and no noise

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

7. The factory is equipped with protection and alarm devices for leakage, water leakage, and motor overload to ensure the safety and security of the factory products

Equipment usage conditions:

During continuous operation, the temperature of the medium should not exceed 40 ℃;

2. The pH value of the medium is 6-9.

3. Deep submergence depth of 10m.

Precautions for equipment installation:

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

2. The sludge reflux pump adopts an automatic coupling installation system, which can quickly lift the equipment for inspection and maintenance without any mechanical disassembly, making installation convenient and fast.

3 . Except for the wall penetrating pipe that needs to be pre embedded, the guide rod and lifting bracket of this equipment are connected to the pool body with steel expansion bolts and do not require pre embedded parts.

4. The embedded parts and snap doors are purchased and installed by the user, and the user should pay attention when placing an order.
