All PowerFlo pumps feature a standardised back (mechanical) end, simplifying part ordering and replacements. Both the pinion assembly and main shaft are supported by individually replaceable bearings, which streamlines maintenance and reduces overall costs. Each pump model has a specific head (water end). If you’re unsure of the model, simply measure the bore, which refers to the brass liner that the pump cups move back and forth in.
