HA HA!
I fitted three of these exact pumps , two in operation at once and one piped in with gate valves to act as a relief/back up pump to feed a bank of huge commercial printing presses at a sustained 5 bar!
had to fit a 50 gall coffin tank as break.
just to give you guys a chuckle, i was subbing to this firm that made paperback books, maintaining washrooms etc, when the local water autority called around, trying to trace a local residents faulty water supply.
the fault lay squarely at the printing firms door alright!
one of the presses (about the size of two busses end to end) had developed a fault within its high pressure compressed air system, and was forcing intermittent blasts of compressed air at over 10 bar back down its water supply line!!
thing is, the foreign guys who installed these presses simply thought it was ok to connect the water supply lines DIRECTLY to yhe mains supply!
local people complained of exploding toilets and taps bursting off the basins!!
as i was on site at the time of water autority visit, it was agreed that i rectify the situation immidiately and proceed to spend the next straight 48hrs re building a pump and header tank system to form a break from mains supply.
each pump cost £580+vat.
