Poor Pump Priming - Tapflo
(OP)
Hi,
I have a problem with the priming of a small Tapflo PTFE double diaphragm pump.
It is sat approx half a metre above a drum of 15% Perocetic which it is meant to pump over into a larger container, sitting next to the tank of acid.
The hose is approx 15mm (ID) and the pump is running at around 3-4 bar. Once the pump is primed there is no issue, but because the pump probably only runs once a week when we do a CIP (clean in place) by the time we come to use it the suction tube has drained all its fluid back to the container and it wont pump (won't prime)
Is there any way I can keep the pump primed, or somehow make priming the pump easier?
it is this type of pump, which should be more than capable for the job.

many thanks in advance

RE: Poor Pump Priming - Tapflo
Valuable advice from a professor many years ago: First, design for graceful failure. Everything we build will eventually fail, so we must strive to avoid injuries or secondary damage when that failure occurs. Only then can practicality and economics be properly considered.

Are foot valves easy to come across? I did a search on google and it came back negative.
Also the pump has been fitted with PTFE balls and is less than two months old, so theoretically there should be next to no wear or so you would expect??
Thanks
