Description

Welch Belt Drive vacuum pump model 1405 giving you an ultimate vacuum of 0.001 Torr (1 micron) and a volumetric flow rate of 3.2 CFM. These belt driven rotary vane vacuum pumps are ruggedized and built to perform and last in demanding environments and applications.

The Belt Driven Rotary Vane Pump has a high oil capacity which also yields a high contamination tolerance. Furthermore, the lower operational RPM, which is about 3 times less than a direct drive rotary vane pump, will result in a longer service life due to lower operational temperature (about 10 degrees less) and less wear and tear.

The trade-off are that these types of pumps are heavier than its direct drive rotary vane counterparts, require more oil, and have more moving parts such as wheel and pulley.

Vacuum Decay Leak Testing Systems
Vacuum Decay Leak Testing Systems are Instruments that detect and quantify a leak by measuring the drop in vacuum (pressure) inside the specimen. During a vacuum decay leak test, the specimen is placed into a vacuum chamber, the vacuum is pulled to a specified setpoint, and the drop in vacuum is monitored and recorded over time. If a leak in the specimen exists, the air will travel from a higher pressure (inside the specimen) to a lower pressure (vacuum chamber). As a results of the additional air, the vacuum levels will drop whereas a leak can be detected and quantified.
Thermocouple Vacuum Feedthroughs
Thermocouple Vacuum Feedthrough are air-tight components that enable the measurement of temperature inside the vacuum chamber during vacuum operations. If you have to run thermocouple wires into the vacuum chamber in order to measure temperature of a specimen during vacuum operation, a thermocouple vacuum feedthrough will enable you to do that.
Our Work: Bubble Leak Testing System with a Dry off Sink used for Leak Testing Large Bags
How do you leak test Large Food Bags? This is the same question a Large Food and Beverage Processor had asked themselves because they had need for a bubble leak testing system which could be used to detect presence of leaks in their large bags. Their requirements were to test several sized bags with the largest bag being 24 inches Wide by 12 inch Deep by 9 inches High. In addition to the bubble leak testing system, they also needed a way to dry the bags after the test.

In this article we will discuss the vacuum levels of an acrylic vacuum chamber. This article also covers the leak rate or the leak tightness of the acrylic chamber. Additionally, we are going to recommend a rule of thumb used for vacuum pump selection based on the size of the vacuum chamber.
