WQP stainless steel submersible sewage pump

WQP stainless steel submersible sewage pump product features:

1. Adopting a large flow channel anti clogging hydraulic component design, it greatly improves the ability of pollutants to pass through, and can effectively pass through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.

2. Reasonable design, reasonable matching motor, high efficiency, and energy saving.

3. The mechanical seal adopts a dual channel series seal, made of hard and corrosion-resistant tungsten carbide, which has the characteristics of durability and wear resistance, and can ensure the safe and continuous operation of the pump for more than 8000 hours.

4. The pump has a compact structure, small volume, easy mobility, and simple installation. It does not require the construction of a pump room and can work underwater, greatly reducing project costs.

5. There is an oil-water probe installed in the pump oil chamber. When the mechanical seal on the pump side is damaged, water enters the oil chamber and the probe generates a signal to protect the pump.

6. A fully automatic safety protection control cabinet can be equipped according to user needs to monitor pump leakage, electric leakage, overload, and overheating, ensuring reliable and safe pump operation.

7. The double rail automatic coupling installation system has brought great convenience to the installation and maintenance of pumps, and people do not have to enter and exit the sewage pit for this.

8. The float switch can automatically control the stop and start of the pump according to the required water level changes, without the need for a dedicated person to supervise.

9. Ensure that the motor operates without overload within the range of head.

10. According to the usage scenario, the motor can adopt a water jacket external circulation cooling system, which can ensure the safe operation of the electric pump in a dry state without water.

11. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage scenarios.

WQP stainless steel submersible sewage pumpProduct applicable locations:

1. The discharge of severely polluted wastewater from factories and businesses.

2. Urban sewage treatment plant drainage system.

3. Sewage drainage stations in residential areas.

4. Civil air defense system drainage station.
5. Wastewater discharge from hospitals and hotels.

6. Municipal engineering and construction sites.

7. Exploration and mining supporting equipment.

8. Rural biogas digesters for farmland irrigation.
9. The water supply system of a water plant.

Product usage conditions:

1. The medium temperature does not exceed 60 ℃, and the density is 1.0-1.3kg/dm3. The pH value is within the range of 5-9.
2. For pumps without internal self circulating cooling systems, the exposed liquid level of the motor part should not exceed 1/2.
3. In general, the pump must be used within the range of head to ensure that the motor is not overloaded. If it needs to be used within the full head range, it should be specified separately when ordering for the manufacturer to manufacture.
4. The current of the pump motor during operation shall not exceed the rated current of the motor.

Product Structure Description:

1. The WQP and QWP stainless steel submersible sewage pumps consist of a motor and a pump, which are separated by an oil isolation chamber and mechanical seal components. They are electromechanical integrated products, and the motor and pump share the same shaft (rotor). The entire length of the water pump is short and the structure is compact. Equipped with multiple protective devices to ensure safe and reliable operation of the pump.

2. The main functions of its components are as follows:
Signal line 1: Equipped with a fully protected water pump control cabinet to protect the pump, including water leakage, phase failure, short circuit, overheating, motor overload, and other items.
Motor stator 8: adopts B-level or F-level insulation.
Water leakage probe 11: This component is installed in the oil chamber. When the mechanical seal is damaged and water enters the oil chamber, the probe can send a signal to the control system to protect the pump.
Mechanical Seal 13: Adopting a dual channel series seal and using a new type of hard and corrosion-resistant tungsten carbide material, it has the characteristics of reliable sealing, wear resistance, and long service life.
Impeller 17: The impeller adopts a single or double channel structure, which has strong passing capacity and can pass large materials and fiber waste, reducing blockage and entanglement failures.
Pump body 15: Paired with the impeller, the pump has high efficiency.
Sealing ring 18: installed at the mouth ring of the pump body. When the impeller wears out the mouth ring due to operation, the sealing ring can be replaced to ensure the normal operation of the pump.
