Sewage submersible pump is a drainage equipment that operates in a submersed manner, is free from blockages, and can handle wastewater containing solid particles and fibers. The main difference from ordinary clear water submersible pumps lies in the impeller structure - the sewage submersible pump adopts single-channel, double-channel, vortex-type or impeller with cutting blades, which can allow solid particles with a diameter approximately one-third of the outlet diameter to pass through, and can handle fibers up to 5 times the pump diameter. The motor and the pump are integrated and submersed in the medium for operation. The motor is isolated from the sewage through an oil chamber and a double-end face mechanical seal, with a protection level of IP68, ensuring reliable long-term underwater operation.
Product structure diagram
Coaxial integrated submersible structure: The motor is located at the top of the pump, and the water pump is at the bottom. They are connected coaxially through a coupling and the entire machine is vertically submerged in the sewage to work. The motor has a dry sealed cavity, and the upper and lower bearings support the rotor. During operation, the heat is dissipated through the casing to the surrounding water (medium cooling).
Non-clogging impeller design:
Single/double flow channel impeller (WQG standard type): The flow channels are wide, preventing clogging and entanglement. It can handle large solid particles.
Swirl impeller (WQ high-power type): The liquid is discharged around the impeller, and fibers and solids pass through the center, with excellent anti-blocking performance, capable of handling fibers up to 5 times the pump diameter.
Cutting impeller (WQ-QG type): It has a cutting disc and cutting blades, which cut fibers, hair, toilet paper, and cloth strips before discharging.
Double-end mechanical seal: Oil chamber + double hard alloy (tungsten carbide) mechanical seal, isolating the motor cavity from the sewage for dual protection, ensuring IP68 protection, continuous operation life > 800 hours
Leakage and overheating protection: Oil-water probe monitors the water intake of the oil chamber and issues an alarm or shutdown signal; the motor stator has built-in thermosensitive elements, automatically cutting off power in case of over-temperature protection.
Application scenario
Sewage Submersible Pump: With the characteristics of "no blockage, submersible operation, and no need for pump room construction", it performs exceptionally well in the following scenarios:
Municipal Engineering: Urban sewage lift stations, rainwater discharge pump stations, municipal pipeline maintenance, wastewater intake lifting in sewage treatment plants
Construction Sites: Pit drainage, construction wastewater discharge, rainwater accumulation drainage at construction sites
Commercial Buildings: Basement drainage, underground shopping mall drainage, hotel domestic sewage, hospital wastewater discharge
Civil Defense Projects: Civil defense system drainage stations, air-raid shelter sewage discharge
Industrial Fields: Severe pollution wastewater discharge from factories, wastewater treatment in industrial and mining enterprises, auxiliary equipment for exploration and mining
