- Comparison of pumps
-
This article lists different types of pump and provides a comparison of certain key design features. Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g. irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (eg potable water pumping from wells).[1]
