​High-capacity handling: Efficiently pumps large volumes of sewage and sludge, ideal for industrial/municipal use.
​Durability: Built with corrosion-resistant materials for harsh environments and long service life.
​Automated & energy-efficient: Self-priming, non-clogging design with low power consumption for cost-effective operation.

The 100ZW100-20 self-priming sewage pump is a new type of sewage product, which has the characteristics of simple structure, good self-priming ability, strong sewage discharge ability, and easy maintenance. The technical indicators of the product are ahead of similar domestic products and have reached the world's advanced level.

​Durable cast iron construction ensures corrosion resistance and long service life in harsh environments.
​High flow rate & energy-efficient motor delivers reliable performance for sewage, sludge, and wastewater drainage.
​Compact yet powerful design ideal for construction sites, basements, or industrial applications requiring heavy-duty pumping.

​Compact & Durable Design: Built for harsh environments, featuring robust materials (e.g., stainless steel, ETFE) to resist corrosion and wear.
​High Efficiency: Energy-saving motors with advanced impeller technology for optimal performance in pumping viscous or solid-containing wastewater.
​Submersible Operation: Directly installed underwater, reducing noise, vibration, and maintenance costs while preventing environmental contamination.

· Design is rational and paired with a suitable electric motor, ensuring high efficiency and energy-saving capabilities.
· Mechanical seals feature a dual-seal configuration, utilizing hard-wearing carbide tungsten material, providing durability and wear resistance, capable of safe continuous operation for more than 8,000 hours.
· The stainless steel sewage pump exhibits a compact design with a small volume, facilitating easy mobility and installation. There is no need for a dedicated pump room; the pump can function submerged underwater, greatly reducing construction expenses.

1. The pump is of vertical structure, with the same inlet and outlet diameter located on the same centerline. It can be installed in the pipeline like a valve, with a compact and beautiful appearance, small footprint, and low building investment. If equipped with a protective cover, it can be used outdoors.
2. The impeller is directly mounted on the extended shaft of the motor, with short axial dimensions and compact structure. The pump and motor bearings are reasonably configured, which can effectively balance the radial and axial loads generated by the pump operation, ensuring smooth operation, low vibration, and low noise.
3. The shaft seal is a mechanical seal or a combination of mechanical seals. It adopts imported titanium alloy sealing ring, medium-sized high-temperature resistant mechanical seal, and wear-resistant sealing material made of hard alloy, which can effectively extend the service life of the mechanical seal.
4. It is easy to install and maintain without dismantling the pipeline system. Only by removing the pump unit base nut can all rotor components be extracted.
5. The pump can operate in series or parallel according to the flow rate and lift requirements.
6. The pump can be installed vertically or horizontally according to the requirements of the pipeline layout.

Submersible Sewage Sludge Electric Pump is composed of three main parts: a pump, a seal, and an electric motor. The motor is located at the upper part of the electric pump and is a single-phase/three-phase asynchronous electric motor. The pump is positioned below the motor, featuring a centrifugal impeller and a volute structure. A double-ended mechanical seal is utilized between the pump and the motor, while "O" type oil-resistant rubber sealing rings are employed for static sealing at various fixed joints.

Due to its compact size and lightweight design, this pump is particularly suitable for water extraction in rural wells, agricultural irrigation, landscape watering, household water use, as well as the drainage of industrial water, construction site water supply and drainage, and aquaculture, among other applications.
