submersible sewage pump with cutter impeller for slurry

Its main feature is that it is equipped with a cutting impeller, which can effectively deal with mud, slurry, feces and urine, as well as sewage containing impurities such as short fibers, confetti, mud and sand. This series of electric pumps are widely used in municipal sewage treatment, construction projects, hotels, mines and other sewage and wastewater discharge places.
Submersible sewage pumps with cutting impeller rotate by motor-driven impeller, which forms strong centrifugal force inside the pump body and pushes sewage and impurities to flow to the outlet of the pump body. Unlike ordinary sewage pumps, the cutting impeller is designed with a knife plate inside the impeller and the pump body, which can effectively cut fibers, debris, paper and other solid particles in the sewage to ensure the smooth operation of the pump and avoid the solid matter from clogging the pump body or damaging the pump impeller. The pump body is completely sealed, can be immersed in water for a long time operation, suitable for a variety of complex sewage discharge environment.

submersible sewage pump features:

1. Cutting impeller design:
   • Semi-open rotary cutting impeller: adopting semi-open impeller design with rotary cutting disc, it can effectively deal with sewage containing solid particles, fibers, paper and other impurities, and reduce the risk of impeller clogging.
   • High-strength cast iron heat-treated impeller: the impeller is made of high-strength cast iron material and heat-treated, which is wear-resistant and corrosion-resistant, and can run stably for a long time to deal with sediment and impurities.
2. Durable material and anti-corrosion design:
   • Cast iron pump body, special antirust treatment: the pump body is made of cast iron material and undergoes special antirust treatment, which enhances the corrosion and abrasion resistance and adapts to the harsh working environment.
   • Steel mirror treatment rotor shaft: the rotor shaft is made of steel material with mirror treatment, which reduces friction, improves working efficiency and prolongs service life.
   • AISI304 stainless steel fittings: the parts in contact with water are made of stainless steel AISI304 to ensure that it is not easy to corrode in the long-term use of water containing corrosive impurities.
3. Sealing and protection system:
   • Mechanical seal: advanced mechanical sealing technology is used to effectively prevent the pump from leaking and ensure the long-term stable operation of the pump body and motor.
   • The “O” ring provides a better sealing effect, ensuring no leakage inside the pump body and avoiding sewage infiltration into the motor part.
   • Built-in Thermal Protection Device: The motor has a built-in thermal protection device that can automatically cut off the power when the motor overheats to prevent damage. It can be reset automatically after overheating to ensure the safety and reliability of the equipment.
4. High-efficiency motor with stable operation:
   • Silent bearing: the motor is equipped with silent bearings to reduce running noise, suitable for noise-sensitive environments.
   • Copper wire motor: using high efficiency copper wire motor, providing strong power and long time stable performance.
   • Stator and Rotor National Standard Cold Rolled Silicon Steel Sheet: Adopting national standard cold rolled silicon steel sheet to improve motor efficiency and reduce energy loss.
   • Protection class IPX8: The waterproof design of the motor reaches IPX8 class, ensuring no failure even when used underwater for a long time.
   • Insulation class F: The insulation class of the motor is F, which can withstand higher temperature and adapt to various high temperature environments.
5. Wide voltage adaptation range:
   • Voltage range: 160-230V/50Hz, 340-410V/50Hz, able to adapt to the power system of different regions, with wider applicability.
   • Low-voltage startup: supports 120V low voltage startup, adapting to areas with unstable power, ensuring reliable startup and operation of the equipment.

Submersible sewage pump with cutting impeller is widely used in the following scenarios:

1. Municipal sewage treatment: widely used in municipal sewage treatment plants for sewage transportation and discharge system, especially suitable for sewage containing more impurities and solid particles.
2. Construction site drainage: Sewage and mud discharge from construction sites, including concrete wastewater, mud and liquid treatment in construction waste.
3. Hotel and hospitality sewage treatment: domestic sewage discharge from hotels and hospitality and other places to ensure the stable operation of the sewage treatment system.
4. Mining and industrial wastewater discharge: wastewater discharge from mines, petrochemical plants and other places, with cutting impeller design can effectively deal with ore, dust and other impurities.
5. Agricultural drainage and rural irrigation: sewage and wastewater discharge in rural areas, including biogas digesters, farm irrigation systems and river and pond dredging.
6. Environmental protection and municipal engineering: suitable for municipal engineering in the sewage discharge, desilting work, especially more impurities in the water environment.
