Why is flow alone not enough to select a pump?
Two projects with identical flow can need completely different pumps if one lifts water 5 m and the other 60 m, or if one runs low-pressure micro-sprinklers and the other high-pressure fogging through fine filters. Head is what determines the motor size, the energy cost per hour and often the pump family itself.
Where this sits in greenhouse irrigation system procurement
A greenhouse irrigation system is specified from crop water demand, growing system, water source quality and block layout — those four inputs decide pump duty, filtration, mainline sizing and emitter choice before any supplier is approached.
Typical procurement searches this answers: greenhouse irrigation system · greenhouse drip irrigation design · irrigation system for hydroponic greenhouse · greenhouse water requirement per hectare · fertigation equipment · fertigation system for greenhouse
Inputs that change the answer
- Static lift
- Operating pressure
- System losses
- Operating hours per year
What this answer does not settle
The final selection must sit inside the manufacturer's efficiency range on the actual pump curve.
