The pump is set as motor centrifugal pump in its delivery instead of a liquid controller element or throttle element such as a valve, a faucet, a flap or a slide gate valve. The liquid controller element or throttle element is placed in a line. A pump suction side or a pressure side is directly connected to the consumer, tank or process pump with or without any intermediate line.
