QW (WQ) submersible non clogging sewage pump

QW (WQ) submersible non clogging sewage pumpBased on the introduction of advanced foreign technology and the joint efforts of our research personnel, as well as extensive solicitation of opinions from domestic water pump experts, and after multiple improvements, we have successfully developed and tested various performance indicators that have reached the advanced level of similar foreign products.
QW (WQ) submersible non clogging sewage pumpFlow rate: 7-2400m3/h, head: 7-60m, etc. The submersible sewage pump is designed and manufactured into WL, YW, GW series products with the same energy parameters according to the medium used and the installation method.

QW (WQ) submersible non clogging sewage pumpProduct Features
1. By adopting a unique single or double disc wheel structure, the ability of dirt to pass through is greatly improved, which can effectively pass through the fiber material with a diameter of about 50% of the pump diameter 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. The overall structure is compact, the volume is small, the noise is low, the energy-saving effect is significant, the maintenance is convenient, and there is no need to build a pump room. It can work by diving in, greatly reducing the project cost.
4. A high-precision interference leakage detection sensor is installed in the sealed oil chamber, and a thermal sensor is embedded in the stator winding to automatically protect the water pump motor.
5. According to user needs, a fully automatic control cabinet can be equipped to automatically protect the pump from water leakage, electric 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.
7QW (WQ) submersible non clogging sewage pumpA dual rail automatic coupling installation system can be equipped 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.
9 QW (WQ) submersible non clogging sewage pumpThere are two different installation methods, fixed automatic coupling installation system and mobile free installation system.

QW (WQ) submersible non clogging sewage pumpmain purpose
QW (WQ) submersible non clogging sewage pumpSuitable for conveying granular sewage and waste in industries such as chemical, petroleum, pharmaceutical, mining, papermaking, cement plants, steel mills, power plants, coal processing industries, as well as urban sewage treatment plant drainage systems, municipal engineering, construction sites, etc. Submersible sewage pumps can also be used to pump clean water and corrosive media.

QW (WQ) submersible non clogging sewage pumpInstallation method:
The indoor sewage tank (collection pit) sewage pump adopts three forms of installation: mobile installation (flexible hose) (single pump), fixed installation (hard pipe) (single pump, double pump), and fixed installation with automatic coupling device (single pump, double pump). The flexible hose connection mobile installation is limited to submersible sewage pumps with motor power N ≤ 7.5 kW and discharge pipes DN ≤ 100 mm.

The outdoor sewage tank only adopts one form of fixed installation with automatic coupling device (double pump).

The installation method of the sewage pump used for the drainage pit of the fire elevator should adopt 2 sets of hard pipe connected fixed type or 2 sets of fixed self coupling type, and the effective volume of the collection well should not be less than 2.0 m3, and the rated flow rate of the sewage pump should not be less than 36 m3/h.

QW (WQ) submersible non clogging sewage pumpTerms of Use
1. The medium temperature does not exceed 60 ℃, the medium density is 11.3 × 103kg/m3, and the pH value is within the range of 59.
2. For pumps without internal self circulating cooling systems, the exposed liquid level of the motor part shall not exceed 1/2.
3. The main component material of this pump is cast iron, so it cannot be used for pumping highly corrosive liquids.
