Water enters the ram pump through the supply port and flows around the main valve to the exhaust port.
As the flow increases around the main valve, a differential pressure occurs causing the valve to suddenly close. The flow and mass of water is then directed through the non-return valve into the delivery port at a higher pulsed pressure.
This pressure suddenly reduces causing the main valve to reopen and the cycle repeats.
Turning the adjuster to open
the valve allows flow through
the pump to be regulated so
that a greater flow generates a
greater pressure and water delivery.
This is a typical scenario where water from the source can be diverted to a catchment tank and fed to the supply tank. This provides the supply head pressure for the Papa Ram Pump to work. Water can then be pumped to a higher level, providing ‘free water’ and eliminating the need for a fueled pump or mains water
Note: If you have a dam or weir in the watercourse it can replace the need for a catchment tank.
