Overview
The YJm series couples a centrifugal impeller with an integrated jet ejector so the pump can self-prime from 9 m in typically 20 seconds — the answer for shallow wells, cisterns, and any installation where the pump is mounted above the water source.
Noryl engineering-plastic diffuser and impeller reduce weight and corrosion risk; brass or stainless-steel upgrade paths are available for potable-water service.
Typical Applications
- Shallow-well or cistern draw
- Rooftop tank feed
- Garden and greenhouse irrigation with intermittent supply
- Pressure-tank automatic booster sets
- Installations where the suction pipe tends to admit air
