Do someone here now any technical feature about that pump. It's a
Carpanelli/Liverani model EP-20. What I know about it is that it is a
centrifugal pump with a bypass. I can't find the transfer rate as
Liter per min. or hour, if they can run dry, if they need priming,
etc.

Séb,

I can't find the specifications for the EP-20.

Carpanelli's website is http://www.carpanelli.it/inglese/commerciale.htm;
and their technical support contact is . You can email
them in English, French, German or Italian, as you prefer.

But I suspect only the motor is made by Carpanelli, and the pump itself is
made by Liverani. Their website is http://www.liverani.com/index.htm, and
their email contact is . They have staff who speak
(some) English, French, German, Spanish, and Italian.

Good luck.
