Description

Welch Belt Drive vacuum pump model 1374B-01F giving you an ultimate vacuum of 0.001Torr (1 micron) and a volumetric flow rate of 23 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.

Pressure Decay Leak Testing Systems
Pressure Decay Leak Testing Systems are instruments that detect and quantify a leak by measuring the pressure drop over specified amount of time. Any specimen that is inflated will stay inflated if it is leak tight. On the other hand, of a leak exists in the inflated specimen, air will escape through the orifice and decrease the pressure inside the specimen. The higher the pressure drop, the high the leak.
Belt Drive Rotary Vane Vacuum Pumps
A Belt Drive Rotary Vane Pump is almost identical to a Direct Drive Rotary Vane Pump. The only difference between the two is that the belt drive Rotary Vane Vacuum Pump is driven by a belt. There are several advantages why a belt drive vacuum pump would be preferable. One of these reasons is that the belt drive Rotary Vane Vacuum Pump runs at a slower RPM therefore the temperature created is lower, the wear and tear is less, and the overall lifetime of the pump is longer. The disadvantages are a lower CFM and performance.
Our Work: High Altitude Vacuum Testing of Electrical Connectors and Components
This was an interesting project where one of our customers needed to test wires up to 44 inches long within a high altitude simulation environment. In addition to testing wires, several other electric connectors required altitude testing as well. The altitude requirements were 100,000 feet (30.510 km) which corresponds to 8.36 Torr - a piece of cake when it comes to the vacuum requirements of our chambers.
Related Articles: Bubble Leak Testing using an Acrylic Vacuum Chamber
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.
