摘要
A pump assembly includes an electrical drive motor (2) and an impeller which is connected to the drive motor (2) via a shaft (14). The shaft extends between the drive motor (2) and the impeller, through a seal arrangement with a fluid reservoir (22). A method is provided for detecting a concentration change in a fluid reservoir in the seal arrangement in the pump assembly. A concentration sensor (30) detects a concentration change in the fluid reservoir (22), and a second sensor (32) detects at least one further parameter of the fluid reservoir (22). The sensors are arranged on the fluid reservoir (22). The sensors are connected to an evaluation device (22). The evaluation device (34) is configured to carry out an evaluation of at least one reading of the concentration sensor (30), taking into account at least one reading which is detected by the second sensor (32).
