The Part number is different
The minimum pressure these pumps require is 2 meter's, if you do not have 2 meter’s differential from water level to discharge point,or a minimum of 14 meter's horizontal run, then use a 1" bore discharge hose or your motor will burn out
What is the lowest head pressure
Part numbers have changed to harmonise along with design changes. The part number stated is the current one in use, there are different numbers for OEM products also, if you have any doubts please advise the part number and we will confirm.
