PRODUCT OVERVIEW

Designed around the operating conditions.

ZW self-priming sewage pumps combine self-priming installation with a flow passage intended for wastewater duties. They can be installed above the liquid level, simplifying inspection and maintenance when the suction arrangement is properly designed and sealed.

TYPICAL APPLICATIONS

  • Municipal wastewater
  • Industrial drainage
  • Construction dewatering
  • Wastewater collection

SERIES ADVANTAGES

  • Above-ground installation
  • Self-priming operation
  • Maintenance-friendly access
  • Wastewater-oriented hydraulic passage

APPLICATION FIT

Where this series fits—and what to confirm first.

BEST FIT

Above-ground wastewater pumping where easy access for inspection and maintenance is important.

WHEN TO REVIEW AN ALTERNATIVE

Where the pump can be installed in the pit, a QW submersible sewage pump removes the suction-line requirement.

OPERATING NOTES
  • The suction pipe must remain airtight for reliable self-priming.
  • Priming liquid is required before initial operation.
  • Actual suction conditions must be checked separately from discharge head.
