Page 17: Product Description
Product description 3 Product description 3.1 Function The rotary vane pumps of the HenaLine are single-stage, oil-sealed rotary positive displacement pumps with air cooling and circulatory lubrication. A non-return valve in the vacuum connection closes the in- take line automatically when the rotary vane pump is switched off and prevents an operating fluid return flow. -
Page 18: Cooling
The rotary vane pump is cooled by thermal radiation from its surface, the air current from the two fans and the pumped gas. In case of thermally unfavorable ambient conditions, Pfeiffer Vacuum recommends the use of a pump version with oil/water heat exchanger. - Page 19 Product description ● Locking caps for vacuum and exhaust connection ● Operating instructions 19/62...
