Page 16: 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 17: Operating Fluid Return Via The Float Valve
The vacuum pump is cooled by heat radiation from its surface, the air flow of the two fan impellers and by the pumped gas. In case of thermally unfavorable ambient conditions, Pfeiffer Vacuum recommends the use of a pump version with oil/water heat exchanger. The oil/water heater is installed at the factory. The oil/water heat exchanger cannot be retrofitted. -
Page 18: Transportation And Storage
► Always transport the vacuum pump horizontally or without operating fluid filling. ► Fill in the operating fluid only at the final installation location. Pfeiffer Vacuum recommends keeping the transport packaging and original protective cov- General information regarding safe transport 1. -

4. Lift the vacuum pump out of the transport packaging. 5. Always place the vacuum pump on an adequately sized, level surface. 4.2 Storing the vacuum pump Pfeiffer Vacuum recommends storing the products in their original transport packaging. Procedure 1. Seal the vacuum and exhaust connection. -
Page 20: Installation
Property damage from contaminated gases Pumping down gases that contain impurities (condensate, particles) damages the vacuum pump. ► Use suitable filters or separators from the Pfeiffer Vacuum range of accessories, to protect the vacuum pump. Installation and operation of accessories Pfeiffer Vacuum offers a series of special, compatible accessories for its rotary vane pumps. -
