I just checked prices of rebuilt pumps at JC Beverage Company;
"Our standard price for refurbishing a Series 2 espresso pump is
$38.50 plus shipping."
Not bad considering a new Procon Series 2 costs as much as $200.
Thanks for the heads up Robert.
That sounds very reasonable.
That's one of the reasons I recommend used commercial machines so strongly - there's very little that costs much to replace, as long as the electronics are intact. In that regard, I've seen a few machines with burned out brain boxes and those were the ones where the manufacturer didn't have fuses for protection. Two of those machines I converted to semi-autos and the current owners love them (not to mention how they liked the low prices).
In fact, I've got two Futurmat/Bunn & one Nuova Simonelli and between them I've put ~$250 in parts. But for one machine I did invest ~$400 in paint & metalwork; but I figure it would be a $4000 machine if I bought it new.
The rotary pump is just part of the equation: there is also a motor to drive the pump and a start capacitor to get the motor running. A missing pump & motor is one of the big ticket items to look for: ~$250 for the motor & ~$200 for the pump.
Shocked at what I said or the prices? The machines I recommend have one thing in common; commonality of off-the-shelf parts. About the only unique thing about most
commercial HX machines are the brain boxes and heating elements. Everything else is pretty much interchangeable - which translates to lower cost. You want to see high parts costs, look at the mostly proprietary parts lists of the prosumer machines!
The pstats, tstats, gauges, 2-way & 3-way solenoid valves, heck I've even taken a steam valve from a La Cimbali and grafted it to a Nuova Simonelli and you'd have a hard time identifying it as non-stock.
Of the 60 or so owners of the Bunn ES-1A I know of, I doubt if any of them have put in more than $200 in parts. That's for a machine built in the early 90's using industry standard parts.
