I was given two used diff pumps today. One is a CVC type VMF-10 water cooled pump with a 3/4" inlet and 1/2" outlet. It has a Kamlrok 135W 120V pancake heater that works.
The other is an air cooled model maide by VBC Corp. With a 3/4" outlet and what looks like a KF-40 inlet with a groove on the face of the flange that is smaller in diameter than the standard KF-40 O-ring. The pancake heater for this pump, was made by Wiegand, is burned out, but it is a 135W 120V heater with the same OD but slighter smaller ID as the heater that works.
The questions are: Since the air cooled pump is less complex to operate (I don't want to use water cooling unless I absolutely have to), is it OK to switch heaters on these pumps? Will a standard KF-40 fitting work even though the O-ring doesn't fit in the groove or should I just buy an O-ring that fits the groove and eliminate the centering ring on the "standard" KF connection. Or what kind of an odd ball connection is this.
I was also given about four ounces of Cambridge pump fluid. The pump reservoir is 3-3/4" diameter and 2" high. How much oil do I put in the pump? Is the oil fill volume critical?
