1. The WQS new energy-saving double suction submersible sewage pump is a clever combination of a submersible motor and a double suction pump, which not only has the function of a submersible electric pump, but also has the special performance of efficient and stable operation of a double suction pump.
2. The WQS new energy-saving double suction submersible sewage pump can meet the requirements for use in high head situations, as the mechanical seal operates in a negative pressure state, it has higher stability.
3. Adopting a double suction structure with low water suction level, the motor no longer has axial tension due to the use of a double suction double channel single volute structure, reducing and balancing radial forces, greatly increasing the service life of the pump by three times and improving efficiency by 15%
4. The structure is more reasonable, compact, and aesthetically pleasing, making the pump operation safer and more reliable.
5. The pump equipped with an external circulating water device can work continuously for a long time in low water level situations A pump equipped with a self stirring impeller with self stirring function It can stir the water in the pool to mix sewage and pollutants and discharge them with the pump.
6. The WQS new energy-saving double suction submersible sewage pump adopts a large flow channel anti clogging component design, greatly improving the ability of sewage to pass through, and can effectively pass through shorter fiber materials and solid particles with smaller diameters.
7. Reasonable design, reasonable matching motor, high efficiency, significant energy-saving effect.
8. 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 operation of the pump for more than 8000 hours.
9. The WQS new energy-saving double suction submersible sewage pump has a compact structure, small volume, easy movement, and simple installation. It does not require the construction of a pump room and can work underwater, greatly reducing project costs.
10. The WQS new energy-saving double suction submersible sewage pump is equipped with an oil-water probe in the 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.
11. 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.
12. The double rail automatic coupling safety system has brought great convenience to the installation and maintenance of pumps, and people do not need to enter and exit the sewage pit for this purpose.
13. 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.
14. Ensure that the motor operates without overload within the range of head.
15. According to the usage scenario, the motor can adopt an external circulation cooling system, which can ensure the safe operation of the electric pump in a dry state without water.
16. There are two installation methods: fixed automatic coupling installation and mobile installation, which can meet different usage scenarios.

product overview

The WQS new energy-saving double suction submersible sewage pump is a pump product with a brand new structure developed by our company according to market demand. This series of pumps has also applied for national patents. Solved the disadvantage of high axial tension and easy leakage of mechanical seals in high head situations of single suction submersible electric pumps. Due to its low suction level, simple and practical structure, it also solves the disadvantages of other similar double suction submersible electric pumps such as high suction level, complex structure, and uneconomical practicality Due to the use of a relatively mature single suction submersible pump with a flange installation structure for edge water discharge, it can be installed either in a mobile or fixed manner using guide rails Easy to install, maintain, and use It has the characteristics of significant energy-saving effect, anti winding, no blockage, automatic installation and automatic control. It has a unique effect in the discharge of solid particles and long fiber waste.
Due to the use of a unique dual suction dual channel structure, water enters the pump from both ends of the impeller and flows out in the middle during actual operation. The inlet of the water pump is divided into upper and lower parts, both of which draw water from the bottom. The water level is low in the suction direction. Because the water is drawn from both ends, the isolated oil chamber between the pump and the motor is located at the suction port, and it is always in a negative pressure state during operation. Compared with the single suction structure, it is less likely to leak water. Because the pump draws water from both ends at the same time, the motor does not have axial tension, and the dual channel structure reduces radial force, thereby extending its service life and achieving durability, stability, and practicality.
The hydraulic performance of this pump is mature, and all performance indicators of the product have been tested to meet the relevant standards JB/T5118-2001. After being delivered to the market, the product has been welcomed and praised by a large number of users for its unique efficacy, reliable performance, and stable quality.
This pump is divided into two series: clean water and sewage, and these two series are further divided into three categories: ordinary type, with external circulation cooling water type, and automatic mixing type.

performance parameter

WQS new energy-saving double suction submersible sewage pump usage conditions:

1. The medium temperature does not exceed 60 ℃, the density is 1.0-1.3kg/dm3, and 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.
