Self-priming non-clogging centrifugal horizontal pump

A robust self-priming, non-clogging horizontal centrifugal pump engineered for handling wastewater and liquids containing large solids and long fibers. The pump combines an axial-reflux external-mixing design with a tailored pump body and impeller flow channel to deliver reliable self-priming performance and strong sewage-discharge capability.

Key features

• Two drive arrangements available:
  • ZW (shaft-coupling / split type): pump and motor shafts run independently and are connected via a shaft coupling for easier maintenance and alignment.
  • ZWL (closed-coupled / direct connection): pump and motor shafts are coaxial for compact footprint and direct drive.
• Self-priming functionality eliminates the need for bottom valves or additional priming equipment for many clean-water applications.
• Non-clogging impeller and flow path configured to pass large solids and long-fiber contaminants, reducing blockages and downtime.
• Simple, serviceable construction that eases inspection and routine maintenance.
• Designed for high efficiency and energy-conscious operation in demanding wastewater and mixed-suspension applications.

Typical applications

• Municipal sewage and drainage systems
• River and pond pumping, aquaculture
• Light industry and process wastewater
• Paper mills, pulp handling, textile and fiber processing
• Food and chemical processing where suspended solids are present

Notes

• Offered in split-coupled (ZW) and close-coupled (ZWL) configurations to suit installation constraints and maintenance preferences.
• Model example provided by the supplier: ZWL100-80-20. For selection, specify required flow, head, motor rating and solids-handling requirements so the correct size and materials can be recommended.
