Vacuum Pump Performance Curves for Saturated Air Evacuation

Product Description

The characteristic curves are based on the evacuation of 100% saturated air with a temperature of 20℃ . Discharge pressure is

1013mbarA, and the operating liquid is water with a temperature of 15℃ , tolerance ±10%. The inlet pressure below 27mbarA are

achieved with the vacuum pump and connected gas ejector (accessory).

Higher vacuum, lower water consumption and better

● Patented compact design, fewer parts, smaller size.

● 100% oil-free design.

● Special Lobe purge interface design.

● Unique external open inspection window.

● A variety of materials are available.

● A variety of vacuum pump accessories are available,

including cavitation protection valves, constant flow valves for operating liquid and suction and quick connections on suction and discharge.

● It can operate efficiently and stably over a wide range of pressures from 27mbar.a to atmospheric pressure

● Simpler structure and less footprint.

● More environmentally friendly, to ensure that the process medium clean without oil pollutions.

● To meet the needs of self-cleaning pump under operating conditions, cleaning is easier and prolongs the service life of the pumps.

● It is easyer to repair and replace the valve plate without disassembling the pump

● Suitable for a variety of harsh working conditions.

● Accessories make pump installation and use easier and more reliable
