Cutting Submersible Sewer Pump

Cutting Submersible Sewage Pump with Cutter Impeller

Electric cutter submersible pumps with cutter system for grinding solids into small pieces. Suitable for free standing wet installation (with rigid or flexible pipeline connection) and for wet installation on automatic coupling foot.

Cutter submersible sewage pumps are specifically designed for handling wastewater containing solids that are prone to entanglement and clogging.

A submersible sewage cutter pump is an electromechanical device that integrates a water pump and a cutting mechanism (a cutting disc or blade). Designed to operate completely submerged in the liquid being pumped, its core function is to cut and crush solid debris such as long fibers, plastic bags, cloth strips, and hair into fine particles before pumping them out along with the liquid.

Powerful Cutting Sewage Pump for Heavy-Duty Sewage and Sludge Handling. WQ-GN powerful vortex cutting submersible sewage pump has the characteristics of energy saving, anti-winding, no clogging, automatic installation and automatic control, etc. It has good effect in discharging solid particles and long fiber garbage. 

The cutting submersible sewage pump adopts the advanced impeller structure and new mechanical seal, which can effectively transport solids and long fibers. Compared with the traditional impeller, the impeller of this pump adopts single-channel or double-channel form, which is similar to a curved pipe with the same cross-section size, and has very good flow performance. With a reasonable volute chamber, the pump has high efficiency. The impeller has been tested for dynamic and static balance, so that the pump has no vibration during operation.

WQ-GN powerful vortex cutting submersible sewage pump product features:

1. The large flow channel anti-clogging hydraulic component design greatly improves the dirt passing capacity, and can effectively pass fiber materials 5 times 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 double-end face tandem seal, which is made of hard and corrosion-resistant tungsten carbide. It is durable and wear-resistant, and can enable the pump to run safely and continuously for more than 8,000 hours.

4. The pump has a compact structure, small size, easy movement and installation. There is no need to build a pump room. It can work by submerging in water, which greatly reduces the project cost.
5. An oil-water probe is installed in the pump oil chamber. When the mechanical seal on the water pump side is damaged, water enters the oil chamber and the probe generates a signal to protect the pump.
6. According to user needs, it can be equipped with a fully automatic safety protection control cabinet to monitor the water leakage, electric leakage, overload and overtemperature of the pump to ensure reliable and safe operation of the pump.
7. The double-rail automatic coupling installation system brings great convenience to the installation and maintenance of the pump, and people do not have to enter and exit the sewage pit for this purpose.
8. The float switch can automatically control the start and stop of the pump according to the required water level changes, without the need for special supervision.
9. Ensure that the motor is not overloaded within the operating head range.
10. Depending on the application scenario, the motor can adopt a water-jacketed internal circulation cooling system to ensure the safe operation of the electric pump in a waterless (dry) state.
11. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage occasions.

Applications include:

Homes and commercial buildings: Domestic wastewater from bathrooms and kitchens, especially those without fine filtration.

Hotels, hospitals, and schools: Wastewater from these locations often contains hair, rags, and sanitary items, which can easily clog conventional pumps.

Food processing and catering: Handling wastewater containing debris, grease, and fibers (such as vegetable leaves).

Animal husbandry: Handling wastewater containing feed residues, animal manure, and bedding.

Industrial: Handling industrial wastewater containing impurities such as fibers, paper pulp, and plastic film.
