High-efficiency submersible sewage & wastewater pump

This submersible sewage pump is built for tough environments. With a 4-pole motor above the pump body and a double mechanical seal, it reliably handles sewage, sludge, and liquids with solids. Its compact, high-efficiency design suits municipal, industrial, and construction use. Made from corrosion-resistant materials, it ensures long-term, low-maintenance operation.

Characteristics

Motor mounted on top, pump body below, enabling stable submersible operation in sewage environments.
Double-end mechanical seal and oil-resistant “O”-ring static seal ensure excellent leak prevention.
Suitable for fluids with suspended solids, slurries and sewage mixtures.
Compact, high-flow construction enabling high efficiency in challenging installations.
Durable materials and reliable design reduce downtime and maintenance costs.

Introduction

WQ and WQD sewage and wastewater submersible electric pumps(hereinafter referred to as "electric pumps") are composed of three parts the water pump, the seal, and the electric motor. The electric motor is located at the upper part of the electric pump and is a single-phase or three-phase asynchronous motor.A double-ended mechanical seal is adopted between the water pump and the electric motor, and an "O"-shaped oil -resistant rubber sealing ring is used for the static seal at each fixed spigot.

Peculiarity

This series of electric pumps features a compact structure, large flow rate, high efficiency, and easy operation. The mechanical seals at key positions are made of hard alloy and high - quality silicon carbide, which have excellent anti-corrosion, anti-leakage, and durability characteristics.
