Choose with a Clear Understanding of the Job

Start with the emitter or sprinkler's required pressure and simultaneous flow, add elevation and pipe/filter losses, then check the pump curve at that working point.

Sprinklers need pressure and flow simultaneously at the nozzle. The maximum-flow claim usually comes from a low-head test; hose loss, height, filters and multiple heads can push the real duty point beyond a drainage pump's curve.

Only if its performance curve meets the combined required flow at the pressure both zones need. Zone valves and filters change the system curve. A float switch is not a constant-pressure controller.

Check emitter pressure and flow, filter fineness, sediment, water level, pipe length and switching control. A pump inlet screen alone may not provide the filtration required by a drip system.

A dirty-water pump may remove bulk water within its documented solids limits; a low-level clean-water pump may finish only after remaining water and the inlet are confirmed suitable and clean.

The inlet geometry, minimum operating level and control-stop point limit how far it can drain. A dirty-water pump designed to pass soft debris is not necessarily designed for floor-level suction. Consider a separate low-level clean-water finishing stage only when the remaining water is suitable.

No. Residual water, minimum safe starting level and float-switch actuation level are distinct. QDX-PH and QDX-PT have different control arrangements, so check the exact model manual rather than inferring automation from residual level.

Do not assume it can. Compare the model's particle-size and liquid restrictions with actual sediment, including its abrasiveness and fibre content. A stated soft-solids size does not establish suitability for hard sand, slurry or sewage.

No. Ingress protection does not demonstrate chemical or salt resistance. Match all wetted metals, polymers, elastomers, bearings and electrical details with the liquid's salinity, treatment chemicals and duty.
