Ahh, sorry Mark....
I thought you had a pretty full-on workshop at your disposal. I wasnt really intimating that you should repair the pump for the job in hand now but rather that you could maybe refurb one or two pumps for future backup and gain practical experience at the same time.
Yep, youve got to be careful matching pump capacity to motor output..... its very easy to get it wrong if you dont have pump curves handy and then could also lead to burning out an otherwise good motor. Anyway, its good to see that youre back in action again, thats the main thing ;)
