MSW-370 ULTRA HIGH VACUUM BELTLESS DIRECT DRIVE VACUUM PUMP “MAC” |
|
|
- A direct drive vacuum pump is driven at a high rotational speed of 1425 revs/min compared to a belt driven pump of 600 revs/min. 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.
- Pump's 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 unlikehood 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).
- To work on 220 / 230 volts A.C. supply.
