I picked up a early 80's gaggia 2 group machine but it is missing the pump . I cant afford a rotary pump at this time but the vibration pumps i think i could afford . Would it work for the short term ? Also my machine had 2 plugs a 220 plug and a 110 plug . the 110 plug is actually the power cord to the pump i found this out by plugging it all in and it blew the ground fault on the outlet then turned on the lights in the room . I measured the output and it is 220 volts so i need a 220 pump . This is all new to me and any help would be much appreciated
