WQP high efficiency 100m3/h stainless steel submersible sewage pump

100m3/h stainless steel submersible sewage pump Product Overview

The WQP Stainless Steel Submersible Sewage Pump is specifically designed for handling wastewater containing solid particles and fibrous materials. Made from high-quality stainless steel, it boasts strong corrosion resistance and a long service life. This pump is suitable not only for residential wastewater discharge but also finds wide application in municipal projects, construction sites, mining, and other scenarios requiring sewage treatment.

100m3/h stainless steel submersible sewage pump Product Main Features

  • High Efficiency & Energy Saving: With an optimized hydraulic model design, this pump offers higher efficiency, ensuring powerful suction capabilities while achieving energy savings and emission reductions.
  • Robust and Durable: The selection of superior stainless steel material effectively resists corrosion, ensuring stable operation over a long period.
  • Easy Maintenance: Featuring a compact and rational structure, it simplifies disassembly and maintenance, significantly reducing users' post-maintenance costs.
  • Safety and Reliability: Equipped with multiple protection devices such as overheating protection and leakage protection, ensuring safety during use.

Structure Description of WQP Stainless Steel Submersible Sewage Pump

The WQP series stainless steel submersible sewage pumps consist of two parts: the motor and the pump, separated by an oil isolation chamber and mechanical seal components, making them electromechanical integrated products. The motor and pump share the same shaft (rotor), resulting in a shorter overall pump length and a compact structure. It comes with various protective devices to ensure reliable pump operation. The main components function as follows:

  • Signal Line: Comes with a full-protection water pump control cabinet, providing comprehensive protection to the pump against water leakage, phase failure, short circuit, overheating, motor overload, etc.
  • Motor Stator: Uses B or F class insulation.
  • Leakage Sensor: Installed in the oil chamber, it can send signals to the control system to protect the pump when water enters due to damaged mechanical seals.
  • Mechanical Seal: Employs dual-seal series connection made of new hard-wearing and corrosion-resistant tungsten carbide material, featuring reliable sealing, wear resistance, and a long lifespan.
  • Impeller: Designed with single or double channel structures, it has strong passing capacity, capable of passing large materials and fibrous waste, reducing blockages and entanglement issues.
  • Pump Body: Used in conjunction with the impeller to achieve high efficiency of the pump.
  • Sealing Ring: Located at the mouth ring of the pump body, it can be replaced when wear occurs to ensure the pump operates at optimal efficiency.
