Vacuum Pumps

Piston Vacuum Pumps
Piston Vacuum Pumps are devices that generate a vacuum through the workings of an internal piston. Several advantages of a piston pump include, low maintenance, no oil mist emission since it’s an oil free vacuum pump – the shortcoming are not as high of vacuum levels and volumetric flow.
Rotary Vane Vacuum Pumps
Rotary Vane Vacuum Pumps are the most widely used vacuum pump in the industry. When it comes to performance at a reasonable price, rotary vane vacuum pumps are the way to go. Many Rotary Vane Pumps can achieve 2 to 5 milliTorr vacuum rating at a good volumetric flowrate (2 to 20 CFM) at a very reasonable price (hundreds to a few thousand dollars)
Diaphragm Vacuum Pumps
Diaphragm Vacuum Pumps are utilized in environments where low noise, no oil mist emissions, low maintenance, and no product cross-contamination are required such as hospitals or labs.
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.
