I would like to use a pair of equal diameter spur gears to connect opposing friction drive rolls ("pinch rolls"). The hardened steel rolls will be about 3 inches in diameter (I can specify this) and the strip will be between .035 and .058 inches thick, therefore the center distance will need to...
Does anyone know if there is a flexible polymer tubing (in the 1/2" OD range) that can handle fluid flow inside at 80C under 27" Hg vacuum (about 50 Torr). If so, how to connect it (metal compression fitting, flared, barbed)? Most charts I see give vacuum ratings at 72F. Also, don't know the...
I have questions relating to a diaphragm vacuum pump. I am looking for a diaphragm vacuum pump that can pull down a tank to between 50 and 100 Torr and at the same time push the outlet to another tank sitting at 15 psig. I see some pumps that have ratings for both max vacuum inlet and max...
I need to find a pump that will circulate hot Limonene to create flow within a heated vessel. The Limonene will be at 80C and in a vessel that has been pumped down to 1 psia. It will be just under it's boiling point (VP at 80C is just over 1 psi. Properties of Limonene are; Sg .84, 0.9 Cp (at...
