These vacuum pumps have a suction limit of 40, 50, 65, 75, 90 and 105 cum/h. The vacuum grease with oil recirculation is balanced through two oilers placed in correspondence of the help bearings.
The rotor is fitted on the engine shaft and upheld by free direction housed in the two pump ribs. The pump and the electric engine are, in this manner, two autonomous units and altered onto an extraordinary help and associated with one another by means of a flexible transmission joint. This permits utilizing standard electric engines, in the shapes and sizes demonstrated in the table.
The pump is cooled on the surface with high temperature being scattered from the external surface, by method for an outspread fan put between the engine and pump. An oil recuperation tank is introduced on the pump debilitate. This tank holds a separator filter that anticipates oil fogs and diminishes clamor. They are ideal for non-intense use.
