Need to push sewage up high or a long way? The high-head ZWL models reach 60–80 m. Here’s which units to look at and how head really adds up.
| Flow Rate | 8–800m³/h |
|---|---|
| Head | 10–80m |
| Power | 1.5–75kW |
| Inlet / Outlet Diameter | DN25–DN300 |
| Material | Cast Iron,SS304，SS316L |

Most self-priming sewage pumps are low-head machines. But some jobs need real lift — pushing effluent up a tall building, over a levee, or a long way across a site — and for those the ZWL direct-coupled self-priming sewage pump has genuine high-head models that reach 60 to 80 m.
When you need head, these are the ones to look at:
These run on larger motors (22–45 kW) to make that head, and they still keep the non-clog, self-priming design — so you get real lift *and* the ability to pass solids and fibre, which is unusual in one pump.
When you’re pushing a long way, don’t size on the vertical lift alone. Friction in a long or narrow discharge line, plus every bend, adds head the pump has to overcome. A “50 m lift” job with a long pipe run can easily become a 60 m-plus total-head duty. Size the pump to the *total* head — vertical plus friction — with a bit of margin, or it’ll move less than you expected.
Tell us the vertical lift, the pipe length and the number of bends, and we’ll work out the total head and pick the right high-head ZWL.
ZWL Direct-Coupled Self-Priming Sewage PumpA self-priming pump holds liquid inside — which can freeze in winter. Here’s how to protect a ZWL pump in cold weather so it primes when you need it.
ZWL Direct-Coupled Self-Priming Sewage PumpWhen one pump isn’t enough or downtime isn’t an option, ZWL pumps run in parallel or duty/standby. Here’s how to set that up sensibly.
