  • Mechanical efficiency | KSB

    Mechanical efficiency. Mechanical efficiency (ηm) is described as the ratio between the power input (P) minus the mechanical power loss (PL.m) and the power input itself: Power loss refers primarily to the friction loss in pump bearings (e. g. plain and rolling element bearings) and shaft seals. It typically consumes 0.5 to 2 % of power input, ...
