Description

Welch Belt Drive vacuum pump model 1399 giving you an ultimate vacuum of 0.001 Torr (1 micron) and a volumetric flow rate of 1.2 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.

We make Robustly Designed and Quality Engineered Systems. What are you building? Take a look at the links below and discover some of the cool things we make.

Altitude Package ASTM D6653 Leak Testing Systems
Altitude Package (ASTM D6653) Leak Testing Systems, or Testing Systems which test the effect of higher altitude on packages are vacuum systems that consist of a vacuum chamber, a vacuum controller, and a vacuum pump. The goal of these package testing systems is intended to test and investigate the effects of higher altitudes on the seal integrity, package quality, or container closure integrity.
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: Custom Vacuum Chamber with Blank Plate
You are looking at our standard Acrylic Vacuum Chamber, Hinged Door with Clamps. There is only one difference; this vacuum chamber has a blank acrylic plate that is connected to and aluminum plate which in turn is anchored to the side wall of the acrylic vacuum chamber. This blank plate is there to enable our client to add vacuum feedthroughs to the side wall in the future

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.
