Oil sealed rotary vane pumps generally come in either 2 or 1 stage design.It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system.Well consider this, an 8 CFM pump will get you to 100,000 microns more quickly then a 4 CFM Pump.You need a pretty good vacuum pump to draw down to 500 micron or less.Despite the different configurations, most vane pumps operate under the same general principle described below. 1. A slotted rotor is eccentrically supported in a cycloidal cam.
They, like most oil sealed rotary vane vacuum pumps are designed to pump air or gas, not necessarily liquids.This type, which is often referred to as a Vacuum Regulator, is actually a Back Pressure Regulator because the pressure controlled is at the inlet port.Because the manufacturing tolerances of the pumps are so tight, they will not function properly and may actually lock up attempting to pump liquids.Vacuum sealing pumps for food storage bags are small transfer pumps that suck the air out of the storage bags.
