Hello guys
I have Rancilio Silvia V3 the European version 220v
And needs to be replaced Ulka Pump
This image of the original pump



Because of the frequency in my country 60Hz 220v

I need to replace it with a pump operating at 60Hz or both 60hz/50hz

I found this pump



http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 0808830724

My question now. Can I replace it? Or there is a difference? Or will not fit my Silvia
Thanks for any help

You need to get a pump EAX5 or EAP5 that work under 220v - 60hz
(It's easy way to find proper one, check 64Watt and have a duty time 1 minute work, 2 minute idle.

Thanks for the reply

Can you tell me
Why can not use the Model
Ulka EX5 Vibratory Vibration pump 220v 60\50Hz
The same wattage
Same time
Only difference that it works on a 60Hz
It seems similar

EX5 and EP5 are not the same model.
Different curve PressureVsFlow
Check at ulka site for further details.
Anyway, if a machine is designed to work with EP5, I would say you should better go for it.

Yes. No.

The X is for brass output fitting and P is for nylon output fitting ("plastic"). If a pump rated 50/60Hz is run at 60Hz, it will pressurize faster than at 50Hz, but otherwise it makes no difference. The "2/1 min." notation on the label above means it needs 1 minute of rest after 2 minutes of run time.

My friend is bringing his V3 over from Switzerland. We are going to run 60cycle 220V to his coffee bar so he can run his 50Hz euro gear.

Electronics matter the most when it comes to 50/60 cycle electric. Here in the U.S. we are lazy and time our clocks to the mains frequency because it's close enough. When it comes to motors, it doesn't matter as much. The 50 cycle vibe pump will run a little faster, but in the big picture, the duty cycle matters more.
