A-370 ULTRA HIGH VACUUM BELTLESS DIRECT DRIVE VACUUM PUMP
A direct drive vacuum pump is driven at a high rotational speed of 1425 rpm compared to a belt driven pump of 600 rpm. High speed for larger displacement; close tolerances for better vacuum must be supported by forced oil lubrication.
Oil is pumped into the mechanism by a simple but reliable oil pump, via the distributor and anti-suckback valve (non-return valve).
Oil enters the mechanism in the bearing between the stages.
Motor, end bearing and external shaft seal are lubricated by filtered oil from the oil pump region.
Oil for the high vacuum stage is degassed in the center bearing between the two stages. This also ensures better vacuum.
Pumps motor is cooled by its own blower.
In addition, between the motor and the pump a fan is fitted to air cool the pump along its ribs.
The pump employs a unique and well proven anti-suckback arrangement. Even in the unlikelihood of this mechanism failure to seal, air venting rather than oil suck-back will occur.
A thermal overload safety device is fitted as standard to protect pump and motor (single phase only).
