DN50-DN250 ST Type Non Clogging Self-priming Sewage Pump
Head Range：3-31m
Motor Power：0.75-90 KW
Inlet/Outlet Range：DN50-DN250
A standout feature is its ability to operate without a bottom valve, ensuring rapid self priming pump water after the first filling. Thanks to its superior discharge performance, this sewage water pump is an ideal choice for diverse sectors, including municipal infrastructure, industrial effluent treatment, agricultural irrigation, and construction site drainage.
Pump Key Features
Non-Clogging Design: The semi-open impeller effectively handles solid particles and fibrous material, effectively preventing clogging.
Portability: The pump unit is mounted on a wheelbarrow-style portable frame with two rubber wheels for easy transport and movement.
Pump Main Advantages
Easy Maintenance: Many models feature a back-pull-out design, allowing the entire rotating assembly (impeller, seal, shaft) to be removed without disconnecting the pump casing or piping. This significantly simplifies maintenance, repairs, and inspections, saving time and labor.
Reliable Operation: Crafted with heavy-duty structures and long-lasting materials such as cast iron and stainless steel, these pumps maintain consistent, reliable operation even under severe working conditions. Wearing parts including wear plates are designed to be replaceable, which effectively prolongs the service life of the pump and cuts down maintenance expenses.
Enhanced Seal Life: Some designs incorporate pump-out vanes on the impeller shroud. These vanes help reduce pressure buildup behind the impeller, which in turn minimizes stress on the seal and bearings, leading to extended component life.
Pump Application Scenarios
- Used for scenarios such as river pond aquaculture, farmland irrigation, orchard drip irrigation, etc., it can extract irrigation water sources containing sediment and aquatic plants.
- The self-priming function solves the problem of frequent irrigation for traditional centrifugal pumps and improves irrigation efficiency.
- Construction site foundation pit drainage, civil air defense system drainage, mine tailings pond drainage, etc.
- Adapt to high lift and high flow conditions to ensure stable operation of the drainage system.
- Rapid deployment and efficient drainage of temporary drainage tasks such as urban waterlogging, flood rescue, and pipeline maintenance.
Service Assurance
- Precise Demand Matching
Free on-site condition assessment with customized solutions (flow rate, head, and piping configurations precisely tailored to operational needs).
- Rapid Delivery Response
Standardized modular design shortens delivery cycles by 30%, with priority processing for emergency project requirements.
- Flexible Warranty Policy
