the problem is the aluminum pulley has a nipple on the front like a press on pulley has ,so it does not leave room for the nut .i had v belt pulley like this but it had the nipple on the backside .(see pics) im thinking of cutting the nipple off and moving it to the back of the pulley .however i dont know if this will weaken the pulley

Pulley style needs to match the pump.

Contact the manufacturer before you modify the pulley.  Because of the off-center leverage applied by the belt, cutting the broach off the pulley may not leave enough support for the pulley to ride square on the shaft.  And from the images you posted, it looks like turning the pulley around will cause too much offset.
