Flow
Water powered pumping traditionally goes back 1000’s of years where it was
used primarily for low head irrigation. More recently, from the late 1700’s
hydraulic ram pumps were developed as an efficient and effective means of
transporting water over long distances and great heights where they have been
utilised to provide water in most parts of the world prior to the advent of
‘previously inexpensive’ mains water and electricity supplies.
Developed within the UK in the mid-90s, the Papa Pump represents a modern,
smaller, lighter and more effective alternative and is used in many countries to
provide water for a wide variety of uses. With the addition of the revolutionary
composite version, Papa continues to ensure that your water transport
requirements are cost-effective and delivered in a reliable and sustainable
system.
Simple water power
By utilising a naturally flowing water source, the Papa pump is able to transport
up to 30% of that water to the desired location, allowing the residual water to be
returned to the natural source. With minimal maintenance and zero fuel costs
and emissions, the Papa Pump will provide you with a clean and efficient system
for your water transportation requirements including agriculture, horticulture,
irrigation, domestic and industrial use.

How the Papa pump works
Water enters pump via supply port and flows around main valve to 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 and 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.

cut 2 ¼” dia. holes in pipe
and screw in filters

supplied with filter

Note: Particulate sizes are calculated. Due to the flexible nature of the discs,
Seradisc filters fitted with lower numbers of discs may allow ingress of
particulates slightly larger than as indicated on the graph.
