Product Details

QWP stainless steel submersible sewage pump

Product Overview

The QWP stainless steel submersible sewage pump has a reasonable design, a reasonable matching motor, high efficiency, and significant energy-saving effect. It is developed by Dingfei Pump Industry by introducing advanced experience in high-efficiency, energy-saving, and unobstructed sewage pumps from abroad and combining our technical strength. All performance indicators have reached the national standard for similar products. Compared with traditional impellers, the impeller of this pump adopts a single or double channel form, which is similar to a curved pipe with the same cross-sectional size, and has very good overcurrent performance. With a reasonable volute chamber, the pump efficiency is high; The impeller undergoes dynamic and static balance tests to ensure stable and reliable operation of the pump. QWP stainless steel submersible sewage pump has advanced and efficient hydraulic performance. Diverse structures and installation methods simplify pump stations and save investment. The motor is separated by an oil chamber, which has no blockage, high efficiency, and significant energy saving. It is the latest product of pump replacement in China and is highly welcomed and praised by users.
The QWP stainless steel submersible sewage pump adopts a large channel anti clogging hydraulic component design, greatly improving the ability of sewage to pass through. It 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. The mechanical seal adopts a dual channel series seal, made of hard and wear-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 800 hours. 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.

Product Features

1. The QWP stainless steel submersible sewage pump adopts a unique single or double blade impeller structure, greatly improving the ability of sewage to pass through. It can effectively pass through 5 times the diameter of the pump and solid particles with a diameter of about 50% of the pump diameter.

2. The mechanical seal adopts a new type of hard and corrosion-resistant titanium tungsten material, which can ensure the safe and continuous operation of the pump for more than 8000 hours.

3. QWP stainless steel submersible sewage pump has a compact overall structure, small volume, low noise, significant energy-saving effect, easy maintenance, no need to build a pump room, and can work underwater, greatly reducing project costs.

4. The pump is equipped with a high-precision anti-interference water leakage detection sensor in the sealed oil chamber, and a thermal sensor is embedded in the stator winding to automatically protect the water pump motor.

5. A fully automatic control cabinet can be equipped according to user needs to automatically protect the pump from water leakage, leakage overload, and overheating, improving the safety and reliability of the product

6. The float switch can automatically control the start and stop of the pump according to the required liquid level changes, without the need for special supervision, making it extremely convenient to use.

The QW (WQ) series can be equipped with a dual rail automatic coupling installation system according to user needs, which brings greater convenience to installation and maintenance, and people do not have to enter the sewage pit for this.

8. It can be used within the full head without overloading the motor.

There are two different installation methods, fixed automatic coupling installation system and mobile free installation system.

Scope of Application

QWP stainless steel submersible sewage pump is suitable for the discharge of severely polluted wastewater in factories and commercial areas, sewage discharge stations in residential areas, urban sewage treatment plant drainage systems, civil air defense system drainage stations, water treatment plants, hospitals, hotels, municipal engineering construction sites, exploration, mining supporting equipment, rural biogas digesters, farmland irrigation and other industries. It can also be used for conveying granular sewage and pollutants, as well as for clean water and corrosive media.

Terms of Use

1. The medium temperature of QWP stainless steel submersible sewage pump shall not exceed 60 ℃, and the medium density shall be 1-1.3kg/dm3.

2. For pumps without internal self circulating cooling systems, the exposed liquid level of the motor part should not exceed 1/2.

3. The use range of cast iron material for QWP stainless steel submersible sewage pump is PH5-9.

4. 1Cr18Ni9Ti stainless steel material can be used with various corrosive media.

Note: If the user has special requirements for temperature, medium, etc., please specify the detailed information of the conveying medium when ordering, so that our unit can provide more reliable products.

Structural Description

The QWP stainless steel submersible sewage pump consists of a motor and a pump, which are separated by an oil isolation chamber and mechanical seal components. It is an electromechanical integrated product, 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.

Main components of QWP stainless steel submersible sewage pump

Signal line: equipped with a fully protected water pump control cabinet, providing comprehensive protection for the pump, including leakage, phase failure, short circuit, overheating, motor overload, and other items.

Motor stator: using B-class or F-class insulation.

Leakage probe: 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: 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: The impeller adopts a single or double flow structure, which has strong passing capacity and can pass large materials and fiber waste, reducing blockage and entanglement failures.
