As far as i'm aware the two most common pumps used and readily available are capable of pumping to heights of 5 metres and 6 metres.
The physical sizes ie 'thread size' and 'distance flange to flange' are these days all common. If your pump is old like mine the 'flange to flange' distance could be about 2ins bigger than todays standard.
This presents a slight problem and I overcame this by retaining the original pump body and using the motor /impeller from new pump of same make.
Since then I purchased 2 'adaptors' that extend the length of each flange about 1 in but have not yet needed to use them.
