What is the Purpose of a Vacuum Pump - Vacaero

In order to create a vacuum within a vacuum furnace (Fig. 2), we need to remove the molecules of air and other gases that are present inside by means of a vacuum pump. The level of vacuum required (Table 1) is that demanded by the application being performed....<<more>>

When to use a Positive Displacement Pump

none can compete with PD pumps for high pressure applications. Pressure limits will depend on the design of each pump, but pressu of 250 PSI (580 feet) are not unusual for a PD pump, with some models (13” hg vacuum). Many dry PD pumps can pull or better and wetted PD pumps (a pump that is not full of liquid but with...<<more>>

Pump Theory - Principles

All pumps use basic forces of nature to move a liquid. As the moving pump part (impeller, vane, piston diaphragm,etc.) begins to move, air is pushed out of the way. The movement of air creates a partial vacuum (low pressure) which can be filled up by more air, or in the case of water pumps, water....<<more>>

Vacuum pumps, piPUMP 23, Compact/Stackable – Piab USA

When the pumps are on, the ejector pump actually uses more energy than the mechanical, however most vacuum applications are intermittent- suction and release- and the ejector pump can follow that cycle and be switched off and on easily along with the cycle which in total gives a much lower energy consumption compared to the mechanical pump that is on all the time....<<more>>
