  • Foam is a two-phase mixture of air and liquid and thus has a lower density than the wash liquor or a rinsing liquid. This may cause the drive power of the pump to decrease due to the reduction in density and the pump performance to deteriorate further due to separation of the two-phase mixture. An improvement in the pumping performance with regard to the changing conditions during a washing program would therefore be desirable.
