Abstract

The present disclosure provides a multi-pump control system (5) comprising a control module (7), a processing module (9),a communication interface (11), and a storage module (13), wherein the control module (7) is configured to a) ramp up the speed of k pumps in addition to a subset j of i pumps of a multi-pump system comprising N pumps and running at a speed É j providing a total head p, wherein N ¥ 2, 1 ¤ k < N and 1 ¤ i < N, wherein the control module (7) is configured to ramp down the i pumps of the subset j from the speed É j to a lower speed É m , wherein the speed É m is the speed required for a subset m of i+k pumps to provide the total head p, and/or b) ramp down the speed of k pumps of a subset j of i pumps of a multi-pump system comprising N pumps and running at a speed É j providing a total head p, wherein N ¥ 2, 1 ¤ k < i and 1 < i ¤ N, wherein the control module (7) is configured to ramp up the i-k pumps of a residual subset r from the speed É j to a higher speed É r , wherein the speed É r is the speed required for a residual subset r of i-k pumps to provide the total head p.
