Our mHV blowers come with an extra third socket on the suction side for pre-inlet cooling. Lube oil can be supplied by splash lubrication.
In addition, a vacuum sealing system seals the conveying chamber while double radial seal rings with a grease barrier seal the driving shaft to prevent leakage. The direction of flow is vertical from top to bottom and the drive is effected through a narrow V-belt (at limited differential pressure) or a direct coupling.
Special advantages of AERZEN mHV blowers:
These blowers are useful in improving production processes in a wide variety of industries, including:
AERZEN blowers with canned drive are designed for the conveyance of neutral (HM version) and aggressive (CM version) gases and are especially used in the industrial high-vacuum technology. Canned motor blowers always work in combination with a backing pump*. This backing pump starts operating at atmosphere. The canned motor blower is connected typically at approx. 50 to 200 mbar and the pump down process begins. Depending on the application, liquid ring pumps, sliding vane rotary vacuum pumps, screw vacuum pumps or blowers are used as the backing pump. When supplied with AERZEN frequency converters and special parameter sets, operation with the backing pump starting from atmospheric pressure is also possible.
*An additional backing pump (multi stage system) is always required when using an AERZEN vacuum blower with canned drive.
