common vacuum pumps
These Vacuum pumps create the most common combination for high vacuums when used in cooperation with one or two positive displacement pumps. Entrapment pumps trap gases in either an absorbed or solid state. They are an ideal addition to receive ultrahigh vacuum suction. Unfortunately, entrapment pumps require more maintenance because the surfaces that captures molecules and ions and need to be regenerated regularly. This causes very short operational time in low and high vacuums.
Vacuum pumps come in many different shapes, sizes and specifications depending on its application use and cost. Some differences include: manufacturing tolerances, sealing material, flow, service intervals, reliability, pressure, admission or no admission of oil vapor and tolerance to dust, chemicals, liquids and vibration. Some vacuum pumps are dry (oil less) or require a rotary vane pump to function. Some are specially made for use in a laboratory or medical or dental setting while other have heavy duty industrial uses. Vacuums can be seen in nearly every aspect of industry.
