Hi Trevor,
I think we may have found one of the problems with the pump and have been given some advice on how we might improve its performance, The gap between the impellor blade and the pump body is a bit wider than it should be and the pump shaft was slightly out of perpendicular so we had a gap of 5 thou on one side of the impellor and 10 thou on the other. The gap should have been almost zero. We also think we can increase pump flow & pressure by increasing the surface area that the impellor acts on,
If all else fails Meziere supplies a remote mechanical pump that flows 90galls per min at 40-50psi which I am advised is what we need, it will mean having to do an amount of re-engineering which is a pain but thats nothing new !
Regards
Iain
