Description

Welch Belt Drive vacuum pump model 1397B-46 giving you an ultimate vacuum of 0.001 Torr (1 micron) and a volumetric flow rate of 17.7 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.

Stainless Steel Vacuum Chambers
Stainless Steel Vacuum Chambers are vacuum chambers made from stainless steel. The advantages of a Stainless Steel Vacuum Chamber are High Vacuum and a Wide Temperature Range of applications.
BNC Vacuum Feedthroughs
Coaxial Vacuum Feedthroughs are vacuum rated BNC connectors that enable you to run BNC from outside of vacuum chamber towards inside of the vacuum chamber without disturbing the vacuum. Triaxial Vacuum Feedthroughs, just like coax vacuum feedthroughs, will enable you to run Triax Connections from outside towards the inside of the vacuum chamber without disturbing the vacuum levels inside the vacuum chamber.
Our Work: Chamber for Vacuum Extrusion System
This is a custom acrylic vacuum chamber build for a high volume manufacturer of parts which are fabricated using vacuum extrusion techniques. The challenge was to build a vacuum chamber system which mated on two perpendicular surfaces; on the bottom and on the rear of the chamber. This was accomplished by incorporating a double gasket mechanism on the bottom and incorporating a clamping mechanism on the rear.

Bubble Leak Testing or Bubble Emission Testing is a procedure where leaks are visually detected and located through the emission of bubbles while the test specimen is submerged in water. In this article, we will talk about using an acrylic vacuum box as a leak detection device. We are also going to talk about the advantage, disadvantage, and the bubble leak emission test procedures.
