Abstract

See full text

A method for controlling the power limit of a pump device includes controlling the power limit of the pump device on the basis of a pump media temperature Tm and an ambient temperature Ta measured inside a control box of the pump device. A pump device, in particular a centrifugal pump, is driven by a motor. The motor is controlled by a control box wherein temperature sensors for measuring a media temperature Tm and an ambient temperature Ta are arranged in the control box so as to control the power limit of the pump device depending on the measured media temperature Tm and an ambient temperature Ta.
