This is a page to help you select a pump for degas and vacuum work. Need to learn the Basics? Click here.
A complete system should include:
1. A Vacuum Chamber, available at Abbess Vacuum Products page
2. Vacuum pump (with the features required for your use)
3. Vacuum grade Hose,
4. Filters or Traps, (to protect the pump and your product)
5. Valves for vacuum control and breaking,
6. Vacuum Gauges. Abbess Vacuum Gauge page.

WELCH – DuoSeal VACUUM PUMPS | |||||
Bypass feature produces higher vacuum at lower RPM. Carries off the last portion of gas and confines excess oil and volatiles to the exhaust side of each stage, leaving less contamination on the other side. Low speed operation reduces the rate of friction and wear on parts so pumps require less maintenance. Gas ballast valves for condensation prevention and removal of contaminates. Large oil capacity absorbs greater amounts of contamination. Single-stage pump 1399B-01 is recommended for continuous duty. All are mounted on a rugged steel frame and include V-belts, pulleys, belt guard, oil supply and instructions. Wired for 115V/230V, 60 Hz, Single Phase. Cord with North American plug and in-line switch provided with motors of 1 H.P. and below. Motors over 1 H.P. require conduit wiring. | |||||

Theoretical Hena Pumpdown Curves
NOTE: These curves are for perfectly dry, empty, clean chambers at sea level as outlined in the Performance Specifications Side Bar. In reality, these curves will be adversely affected by, if nothing else, outgassing of customer’s product (and inadequate cleaning and preconditioning). As a consequence, Abbess recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum. |
