Municipal heavy-duty submersible pump aerobic to anoxic tank submersible sewage reflux pump

Nanjing Sapphire Environmental Protection Equipment Co., LtdWQ typeNon clogging submersible sewage pumpIt consists of two parts: the motor and the pump, which are separated by an oil isolation chamber and a mechanical seal component. It is an electromechanical integrated product, and the motor and pump share the same shaftThe entire length of the water pump is short and the structure is compact. Equipped with multiple protective devices to ensure safe and reliable operation of the pump. The main functions of its components are as follows:

signal line1: Equipped with a fully protected water pump control cabinet to protect the pump, including water leakage, phase failure, short circuit, overheating, motor overload, and other items.

Motor stator8: Use B-grade or F-grade insulation.

Leakage probe11: This component is installed in the oil chamber. When the mechanical seal is damaged and water enters the oil chamber, the probe can send a signal to the control system to protect the pump.

mechanical seal13: Adopting dual channel series sealing and using a new type of hard and corrosion-resistant tungsten carbide material, it has the characteristics of reliable sealing, wear resistance, and long service life.

impeller17: The impeller adopts a single or double channel structure, which has strong passing capacity and can pass through large materials and fiber waste, reducing blockage and entanglement failures.

pump body15: Paired with the impeller, the pump has high efficiency.

sealing ring18: Installed at the mouth ring of the pump body, when the impeller wears out the mouth ring due to operation, the sealing ring can be replaced to ensure that the pump operates at better efficiency.

Installation method of submersible sewage pump:

Fixed wet installation: usingNanjing SapphireDouble rail automatic coupling device, the pump can automatically slide along the double rail to the installation position on the base, and the outlet connection is sealed.
Fixed dry installation: Install the pump bottom on a bracket for fixed dry installation. A pump station suitable for separate collection tanks and water tanks can save space and installation costs, making it a good choice for retrofitting old pump stations with long axis pumps.
