Abstract

A pump system is disclosed including a first pump having a first inlet and a first outlet, and a second pump having a second inlet and a second outlet. The second pump is arranged in parallel with the first pump, and the first inlet and the second inlet are for fluidically coupling to one or more fluid reservoirs. A control system is coupled to the first pump and the second pump for controlling the operation of the first pump and the second pump simultaneously. The control system is configured to measure a value of a first pressure head at the first outlet, measure a value of a second pressure head at the second outlet, control the first pump to achieve a required output and control the second pump by providing a demand for the second pump to achieve a measured value of the second pressure head which equals the measured value of the first pressure head.
