Unique throughout the world: the wide variety of rotors.
Börger has been building rotary lobe pumps for more than 20 years and offers you a range of 21 different pump sizes. Each pump size has up to 9 different rotor geometries available in various materials. The specially patented design ensures that the sturdy rotor core and the shaft remain untouched by the pump medium at all times. Due to the many different factors involved when selecting the right rotor, the special requirements of the customer are always taken into account.
And by the way: rotors available for all sizes can also be fitted into any rotary lobe pump previously supplied. That is regardless, whether it was bought 20 years ago or just last year.
