OK, I just bought a used diffusion pump.
Inlet is about 3 inches.
Outlet is about 1 inch.
Height is about 12 inches.
Water cooled with normally closed thermostat device on the water
jacket.

Since I don't have a spec sheet, I am at a bit of a loss as to how
to proceed.? For instance, how do I determine what volume of oil to
use?? The label indicates that this is an Alcatel model 6063 (which
I have looked for on the 'net but not been able to find specs on).?
There are fields on the label for power, liters/minute etc but the
numbers were not inserted!

The heater is also a bit of a mystery.? There are apparently two
heating elements, currently wired in series but with all three leads
coming out of the can.? Element one (which is physically located on
the outside edge of the heating base) measures 134 ohms.? Element
two (which is located in the center of the base) measures 248 ohms,
but has heavier gauge wires than the outer heater.

Rumor has it that this is wired for 220 volts, but this is not
necessarily accurate.? There is a 4th wire which is tied to the pump
chassic ground and is not shared with the heaters.? If 220 volts
were applied to these two elements in series - power would be about
126 watts.? Is this wattage in the ballpark for a water-cooled unit?

The other way to wire it would be to apply 220 across the elements
in parallel, whcih would produce ~560 watts total dissipation -
which seems perhaps a bit more reasonable for the water-cooled
jacket?

Can anyone advise me about typical wattages for a unit of these
dimensions?? Does anyone have information on a dual-coil heating
element for these sorts of things?

Thanks in advance!
