Description

Welch, Dry, Oil Free Vacuum Pump featuring WOB-L technology. This particular model number is 2585B-50. The free air flow rate is 7.1 CFM and the ultimate vacuum rating is 60 Torr or (27.9inHg of Vacuum). This Pump comes with a power cord and a user manual. This is a very popular vacuum pump among laboratories, educational institutions, pharma, and biotech industries due to the fact that this pump is low maintenance and and oil free (dry) which can be used in indoor and closed rooms and environments without the risk of oil contamination. It does not come with connection hardware you will need to connect this vacuum pump your vacuum system. The Intake Port Thread of this pump is a 1/4 inch FNPT. Connected to this Intake port is a barb hose fitting for the 3/16 inch ID vacuum hose. To connect this pump to you vacuum system, you have two choices:

1. You can either connect a reinforce vinyl hose with 3/16 ID to the already present Barb Fitting.

2. You can unscrew the Barb Fitting and screw on your own fitting. Sometimes going from 3/16 inch ID hose to 1/4 inch ID hose will decrease your pump-down times by a factor of about 1.5.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
Power Vacuum Feedthroughs
Power vacuum feedthroughs are hermetically sealed off the shelf components used to transfer electrical power from the outside of the vacuum chamber into the inside of the vacuum chamber without compromising the vacuum. One example application would be powering an electronic device inside the vacuum chamber

How do you know that you have a good part during your leak test? In order to understand your leak test, you must first understand the Test Decay Curve and what it tells you about your test specimen. There is a certain way that a test specimen behaves during the leak test.
