technologies, gear-type pumps are the most vacuum tolerant handling vacuums up to 10 in.-Hg (254 mm-Hg). Vane-type pumps can handle inlet vacuum up to 6 in.-Hg (152.4 mm-Hg) and piston-type pumps up to 4 in.-Hg (101.6 mm-Hg). Noise and Vibration Vane-type pumps are the quietest and most vibration-free followed by piston- and gear-type pumps in that order. It is worth noting that piston pumps

tors and vacuum pumps. Steam generators A significant development introduced in the new generation of B-class sterilisers is ‘pre-boiling’ the water outside of the chamber by means of a steam generator and then injecting saturated steam directly into the chamber. This provides significant improvement in the speed of sterilisation. Produc-tion of steam using a steam generator also overcomes

The most common vacuum pumps are rotary vane pumps. Rotary vane pumps have a rotating vane inside of a chamber that creates a partial vacuum. The basic varieties of rotary vane pumps are oil-flooded, oil-less and combined.
Types of rotary pumps include cam-and-piston, internal-gear, lobular, screw, and vane pumps. Gear pumps are found in home heating systems in which the burners are fired by oil.

TYPES OF SLUDGE PUMPS . This fact sheet provides information on the two types of sludge pumps, centrifugal and positive displacement pumps. Pumping Sludge, Slurries and Effluent . There are two major categories of sludge pumps: centrifugal (dynamic) pumps where continuous energy increases the flow velocity of the fluid, which is later converted to lift or pressure; and positive displacement
the fluid into the pump housing to fill the vacuum created when fluid or air already in the housing is expelled by the action of the pump. If the pump is capable of start- ing up dry and sucking fluid up an inlet line it is considered self-priming. If its inlet has to be immersed or if the fluid has to be poured into it prior to starting, it is non-self-priming. Centrifugal water pumps use an

Types & Applications of Vacuum Pumps

Vacuum Pumps Their Types And UsesVacuum pumps have been used in different places and served multiple functions over time. Since theinvention of the first vacuum pump by Otto von Guericke in Germany in 1650, vacuum pumps have beenused on large scale and small scale applications. Vacuum pumps unlike conventional pumps remove gasmolecules from a sealed space or enclosure leaving a partial vacuum
The two types of pumps behave very differently regarding pressure head and flow rate: The Centrifugal Pump has varying flow depending on the system pressure or head The Positive Displacement Pump has more or less a constant flow regardless of the system pressure or head.
There are two different types of rotary vane pumps—those for coarse vacuum applications and those for rough vacuum applications. The major The major distinctions between the rotary vane mechanism for coarse pumps and rough pumps are the number of vanes, their tolerances, and the trapping of
