See a working Papa Pump
Improved RAM Pump Performance
The PAPA pump uses only the energy of the flowing water to powers itself. The two primary factors in determining this power are:
1) Flow rate of supply water
The flow rate of your supply water source is quantified in terms of Litres or Gallons per minute. Remember it may vary throughout the year. The pump only needs a minimum 5 litres / minute inflow to operate. Greater inflow amounts will increase the delivered water (*up to approx 80 litres/ minute inflow*)
2) Supply and Delivery Head of the supply water
The velocity of the supply water is caused by the Supply Head, ie the greater the drop from the water intake to the pump location, the higher the Supply Head which creates the pump's power. The factor that consumes the available power of the pump is the height to which the water is to be delivered. This is referred to as the Delivery Head ie the higher the Delivery Head, the less water can be delivered.
The chart shows the PAPA pump output as an approximate percentage of the total flow through the pump is installed. The greater the flow velocity past the pump, the greater the pump performance.
So for 50 litres / minute through the pump- multiply the below % by 50!
Select your Flow rate of water and distance the water drops from supply tank to where the pump will be...see how far it could go!
