Abstract: A pump arrangement, in particular in a coating installation for the coating of components, such as a painting installation for the painting of motor vehicle body components, is provided. The pump arrangement includes a plurality of adjustable pumps for delivering a coating agent, e.g. for delivering a sealing agent for the sealing of weld seams on a motor vehicle body component. The pumps are connected in parallel such that the pumps extract the coating agent for delivery from a common inlet line and deliver said coating agent into a common outlet line. The arrangement further includes a control device for the open-loop or closed-loop control of one fluid variable at the outlet of the individual pumps, respectively, wherein the control device actuates the individual pumps individually, and/or a monitoring unit, which switches the pumps on and off non-simultaneously.
