Abstract
The invention relates to a pump assembly with a pump (4) and with an electrical drive motor (6), as well as an electronic control device (8), wherein the electronic control device (8) comprises a rotation direction recognition module (14) for recognizing the correct rotation direction (CW, CCW) of the drive motor (6) and of the pump (4), the rotation direction recognition module comprising means (22, 24) for detecting at least one performance characteristic value (H, Q, P) of the pump assembly, and being designed in a manner such that on rotation of the drive motor (6), the rotation direction recognition module detects at least one performance characteristic value (H, Q, P) and determines the correct rotation direction (CW, CCW) by way of evaluation of the performance characteristic value (H, Q, P).
