Common Pump Types For Sewage Pumping Stations

1. Submersible Sewage Pump: A Pro at Deep-Water Operations

As a widely used option in pumping stations, the submersible sewage pump operates fully submerged in water, making it ideal for transporting sewage containing solid particles. Featuring a compact structure, it allows easy installation without the need for additional pump rooms, saving valuable space. With an integrated motor and pump body design, it runs quietly, minimizing impact on the surrounding environment. Note that long-term underwater service demands high sealing performance, and integral hoisting is required for maintenance.

2. Self-Priming Sewage Pump: Tackling Complex Working Conditions

Equipped with unique self-priming capability, the self-priming sewage pump can handle liquids with entrained gases, suiting scenarios with significant water level fluctuations. It can start under dry conditions, forming a vacuum quickly via built-in devices to draw in the medium. Typically installed on the ground, it facilitates convenient inspection and repair but occupies more floor space. Its specially designed impeller enables passage of large particles, though its efficiency is slightly lower than that of submersible types.

3. Cutting-Type Sewage Pump: The Nemesis of Fibers

Engineered specifically for sewage containing fibers, cloth strips, and similar impurities, the cutting-type sewage pump comes with a rotating cutterhead that shreds long fibers before discharge. It is particularly suitable for treating domestic sewage, hospital wastewater, and other media prone to clogging pipelines. The blades, usually made of hard alloy, offer excellent wear resistance-however, regular checks on blade wear are necessary. Compared to standard sewage pumps, it has a higher procurement cost but significantly reduces the risk of blockages.
