ZW Series Self Priming Non Clogging Sewage Pump
Product Details
DEPUMP ZW series self priming non clogging sewage pump combines self-priming capability with non-clogging solids handling in a single unit. No foot valve required and no priming water needed at startup.
Compared with conventional self-priming clean-water pumps, the ZW series not only handles clean water but also directly transfers wastewater containing large solid particles and long fibrous impurities.
Core Advantages
No foot valve, no priming water, ready to run
Self-priming height up to 4.5 to 5.5 meters, suction pipe length up to 10 meters. On-site installation requires no foot valve and no manual water filling, significantly reducing operational complexity and maintenance workload.
Strong solids-handling capability, no clogging
Suspended particle diameter up to 60 percent of the pump aperture; long fiber length up to 5 times the pump aperture. Ideal for fibrous, pulpy, mixed and suspended media.
