Standardised Pumps / Close-coupled Pumps Standardised Pumps to EN 733 ■ Product's type and size identificator: see data sheet ■ 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. ■...
