BECKER´s 100% oil-free rotary vane pumps vane marking against grey market parts 851663 BG 21 BECKER WN 124-034 851663 BG 21 BECKER WN 124-034 charge no. material manufacturer drawing no. What else do you find in the market? BG21 = Becker Standard BG26 = Pure Carbon, developed by GBB, problems at high vacuum operation BG28 = Pure Carbon (Rietschle Thomas and eventually Busch) BG24 = similar to Becker Standard, but different supplier, no field experience Note: Sometimes there is also no description at all or a printed description whereas ours is laser marked! for internal use only!

BECKER´s 100% oil-free rotary vane pumps optional VARIAIR UNITS Speed range between 500 to 1100 (1700) rpm (25-60 Hz) Regulating range > 100% Soft start  less strain on mechanical components Reduced maintenance Reduced noise level Energy optimised operation e.g. VAU KVT 3. series

Becker 100% oil-free rotary vane pumps advantages BECKER longer life time of vanes easy and quick checking and changing of vanes no damage by vanes even after breackage easy access to integrated vacuum/inlet filter about 1/3 less parts compared to similar pumps life-time greased bearings  80 m³/h

Becker 100% oil-free rotary vane pumps How to sell? please concentrate on the benefits to the customer (cost of ownership) wearing parts do not necessarily mean more maintenance or higher maintenance costs easy and robust design with only one shaft could be fixed on side in case of failure ( “field serviceability”) integrated inverter increases value of the product and increases maintenance intervals
