David/Grahame , it may be worth getting in touch with Panks in Norwich , they used to be Alcon agents , pumps of all types was their speciality. My Father bought a brand new Villiers/Alcon unit from them when I was a youngster.
I know neither of you will agree , but the Alcon type pumps are not meant to be used for pressure applications , my Father used his commercial sprinkler system driven by a large Godwin piston pump , which we drove using his Petter Atomic diesel , it would operate four commercial sized guns with ease. The Alcon was only used for what it was designed for , just transferring water to large holding tanks for Greenhouse work.
No mention has been made of the use of footvalves???.
