WQ Non-Clogging Sewage Pump Product Features
1. Strong effluent removal capability, no clogging.
2. Reasonable design, with a small motor power and significant energy-saving effect.
3. Utilize wear-resistant mechanical seals.
4. Compact structure, easy to move, simple installation, no need for a pump house, reducing construction costs.
5. Operates across the full range of speeds without overloading the motor.
6. The centerline of the inlet and outlet is aligned, allowing direct installation at any point on the pipe.
WQ Non-Clogging Sewage Pump Main Applications
1. Industrial wastewater discharge.
2. Urban wastewater treatment plant discharge system.
3. Residential wastewater pumping stations.
4. Subway, basement, and civil air defense drainage stations.
5. Hotel and high-rise building wastewater discharge.
6. Discharge of slush from municipal engineering and construction sites.
7. Livestock farm wastewater discharge and rural agricultural irrigation.
8. Self-contained water supply unit for water plants.
9. Mine exploration and water treatment equipment packages.
10. Water supply and drainage for hydraulic engineering.
WQ Non-Clogging Sewage Pump Operating Conditions
The medium temperature conveyed does not exceed 80 degrees Celsius.
2. The medium's density for conveyance ranges from 1 to 1.3 Kg/dm3.
3. The pump is primarily made of cast iron and is not suitable for conveying highly corrosive liquids.
4. When the pump is in operation, ensure good ventilation around the pump.
5. 1Cr18Ni9Ti stainless steel material is suitable for conveying various corrosive liquids.
The significance of the WQ model in non-clogging submersible sewage pumps

Cautionary Notes:
No dry running allowed; liquid level must not be lower than 3/4 of the pump height (except for internal circulation cooling pumps).
2. After installation, test the machine and pay attention to the current. If the current is too high, reduce the valve to control the flow rate or contact the manufacturer for measures (usually due to excessive selection of pump head and flow rate).
3. If there is any缠结 with large fibers like aquatic weeds around the impeller, the machine must be immediately shut down and the debris cleared promptly.
4. When working with highly corrosive liquids, if conditions permit, shut down the pump for extended periods to remove it from the water surface.
5. High-power submersible pumps are designed to avoid frequent startups, with a self-coupled step-down starting method that ensures an interval of no less than 15 minutes between startups.
6. Do not pull or tug on the cables when handling water pumps.
7. Pump with oil chamber, oil change interval is every/6 months
8. The medium temperature should be less than 60°C.
9. Special application conditions require communication with our technical department to determine selection, material, and configuration options.
