Abstract
In the system a primary pump unit (1), driven by pressurised fluid, has its drive (7) coupled to drive a secondary pump unit (6) to pump liquid under pressure to a consumer device (9), such as a washing machine. The liquid is discharged from the primary pump unit (1) through an air gap (4) where it is received by the secondary pump unit to continue the flow of the pressurised fluid to the consumer device.
