Posted Sun Apr 29, 2012, 2:03pm Subject: wega water pump
Hi,
I Have a wega EPU2, it is not plumbed in so the water comes from a container. It seems that since a few days, when the machine is at pressure, if I don't pour a shot every couple of minutes, the water doesn't stay in the pump but goes back to the water container. The hose between the water container and the machine is then hot. Also, if I don't pour a shot for that long, I need to put an external water pump to resend water in the system.
If anyone could help me with that problem, that would be most appreciated.

Hi Florent
What sort of set-up do you have? Most commercial machines with Rotary pumps are designed to be plumbed in to the mains.Whilst some rotary pumps will pull water from a tank, it is not ideal.At the least you should have a 1 way valve in the line to stop your problem.If you keep running the rotary pump dry it will burn-out and they're not cheap to replace

I found that my Wega Lyra needed line pressure to work properly, so I got a FloJet feed pump and that solved my issue. Once it was running on the Flojet then I also an accumulator so the flowjet cycles were less often and more stable.
I've upgraded machines a few times since then, but I still run my setup using the same flojet-based water feed system.

Hi Guys,
Thanks for the input. I run a mobile coffee cart, so the machine is also gas fitted, and it's why it's not plumbed in. The flow jet pump sound like a good idea.
