Design / Operating principle - Pfeiffer Vacuum

Single-stage or two-stage rotary vane pumps or external vane pumps are used as oil-lubricated backing pumps. Screw pumps or multi-stage Roots pumps can be used as dry backing pumps. Pump combinations such as these can be used for all applications with a high pumping speed in the low and medium vacuum range...

High Vacuum Pumps Information | Engineering360 - GlobalSpec

The pumping speed vs. pressure curve shows how the pressure generated by a vacuum pump varies with pumping speed. It describes the pump's performance throughout its probable application range, allowing users to assess the pump's capability at specific operating conditions for different gases. A high vacuum pump...

ROTARY (VANE) VACUUM PUMP

ROTARY (VANE) VACUUM PUMP. A rotary vane vacuum pump is an oil-sealed rotary displacement pump. The pumping system consists of a housing (1), an eccentrically installed rotor (2), vanes that move ... Animation video of the working of a Trivac Rotary (vane) pump ... Because of high pressure on the exhaust side.

Deep Vacuum Principles and Application - Alltemp

micron gauges are critical for High SEER systems. ... Remember these two basic principles: 1. A vacuum pump creates a void toward which the system pressure flows. 2. As pressure decreases in the system during evacuation, flow also decreases. ... 99% of air conditioning and refrigeration work. CFM rule of thumb: CFM...

Vacuum pump - Wikipedia

Second the positive displacement pump backs up the momentum transfer pump by evacuating to low vacuum the accumulation of displaced molecules in the high vacuum pump. Entrapment pumps can be added to reach ultrahigh vacuums, but they require periodic regeneration of the surfaces that trap air molecules or ions...
