The PS18L is an electronic automatic flow controller for household booster pumps. It switches the pump on when you open a tap and off again when the flow stops, so you don’t need a pressure tank or pressure switch. It also protects the pump by switching it off if it runs without water.
- Maximum current: 16A
- Supply: 220–240V single phase
- Digital display
- Fitted as standard to the CPM190, CPM200 and 2CPM25/160 booster combos
A replacement PC board for the PS18L is also available.
