My air diaphragm pump moves hot and cool syrup fast, but when I have COLD syrup to pump, I use a band type barrel heater, let it warm the barrel for an hour or even 2, then pump the warm syrup. My barrel heater is a band type that wraps around the lower portion of the barrel and plugs into 240V outlet to heat.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
