▪
Hydraulic pump efficiency (%) with trimmed impeller: see data sheet
▪
Pump performance curves, including efficiency characteristics: see documented
characteristic curve
▪
The efficiency of a pump with a trimmed impeller is usually lower than that of a
pump with full impeller diameter. Trimming of the impeller will adapt the pump
to a fixed duty point, leading to reduced energy consumption. The minimum
efficiency index (MEI) is based on the full impeller diameter.
▪
>Operation of this water pump with variable duty points may be more efficient
and economic when controlled, for example, by the use of a variable speed drive
that matches the pump duty to the system.
