Product Summary

Mechanical vacuum pumps may well be considered the workhorses of vacuum technology; they are simple in design, require little maintenance, are relatively inexpensive, and can operate for long periods of time without failure. Several mechanical vacuum pumps that we are aware of have operated continuously for fifteen years with only occasional oil changes! The range of pumping speeds for commercially available pumps runs from about 0.5 liters per second to over 300 liters per second.

Mechanical vacuum pumps fall into two basic categories: reciprocating pumps, and rotary pumps. Further distinctions for mechanical pumps include: the number of stages(single stage or compound), the use of oil in a pump (pumps may be oil sealed or "dry") and the means of driving the mechanics of a pump (direct drive or belt drive).

Mechanical vacuum pumps work by the process of positive gas displacement which is during operation the pump periodically creates increasing and decreasing volumes to remove gases from the system, and exhaust them to the atmosphere. In most designs a motor driven rotor spins inside a cylindrical stator of larger diameter. The ratio of the exhaust pressure (atmospheric) to the base pressure (lowest pressure obtained at the vacuum pump inlet) is referred to as the Compression Ratio of the pump.
