This is a horizontal self priming sewage pump that sucks up dirty water by itself and won't get clogged. Unlike most self-priming pumps, the ZW series doesn't need extra valves or water filling. It's great for handling:
1.Water with big solid chunks
2.Long fibers and sediment
3.Industrial wastewater and sewage
4.Mining waste and other dirty liquids
Main Advantages:
Works right away - no complicated setup
Easy to move and install
Rarely needs repairs
Runs smoothly and reliably
The pump contains:
Main body
Spinning wheel (impeller)
Back cover
Special seals
Rotating shaft
Bearing housing
Water intake parts
Air/liquid separator
Application scope
How It Works:
The pump keeps some liquid inside after turning off
When starting, this liquid gets thrown up with air
Liquid flows back down while air escapes
This creates suction that pulls in more liquid automatically
Where You Can Use It:
Works in places up to 45°C (113°F), handles liquids up to 60°C (140°F)
Works with:
Normal water (pH 6-9) for iron pumps
Strong chemicals (pH 1-14) for stainless steel pumps
Can handle:
Solids up to 60% of pump's width
Fibers 5 times longer than pump's width
Total dirt in water shouldn't be more than 15% of weight
Liquid shouldn't be heavier than 1240kg per cubic meter
In Simple Terms:
This horizontal self priming sewage pump sucks up dirty water by itself, won't clog, and works with almost any kind of wastewater - making cleanup jobs much easier!
