Which Sanremo and Isomac machines is this pump listed for?
This pump is listed for Sanremo Sprint and Cube V, plus Isomac Maverick, Millennium, Mondiale, Tea, Venus, and Zaffiro. Check your exact machine version and compare the pump model, electrical ratings, mounting, and water connections before ordering.
What voltage, frequency, and power rating should I check?
This ULKA EAX5 version is rated at 110-120V, 60Hz, and 52W. Match all three ratings to your original pump label and your machine's parts information. A similar-looking pump with a different electrical rating is not necessarily interchangeable.
Which pump model and part reference should I use?
The pump model is ULKA EAX5, and the Sanremo part reference is 10255011A. Use both when checking the replacement against your existing pump or the machine's parts list.
Is this a vibration pump or a rotary pump?
This is a vibration pump, also called a vibratory pump. It moves water through the espresso machine's hydraulic system. It is not a rotary vane pump, so choose the pump type specified for your machine.
What is the pump made from, and is it NSF approved?
The pump has metal and plastic components. It is made in Italy and is NSF approved.
Will this fix poor water flow, and can I install it myself?
If a worn or faulty pump is causing poor water delivery, a correctly matched replacement can help restore normal operation. We recommend having an espresso machine technician diagnose the fault, confirm compatibility, and install and test the pump. Replacing it will not solve every pressure or flow problem.
What comes with the replacement vibration pump?
You receive one replacement vibration pump. Tubing, fittings, and mounting brackets are not specified as included. Have your technician check which installation parts are needed and whether existing components are suitable for reuse.
