The new ONIXline Rotary Lobe Pump. A class of its own!

The new ONIXline.
Compact. Precise. Efficient.

Progressive Engineering.

Börger has drawn on its 25 years of experience in rotary lobe pump construction to develop the new ONIXline pump.
At the heart of the pump are the newly developed rotors. Their advanced geometry together with the flow-optimized pump casing ensure the best efficiency even with high pressures.
The ONIXline rotary lobe pump is used wherever other pumping systems reach their limits.

Compact – impressive performance with minimal space requirement.

  • High flow rate in a space saving design
  • Robust carrier and timing gear combined with precise rotors in a flow-optimized casing ensure the best efficiency even with high pressures
  • Ease of maintenance with MIP (Maintenance in Place)

Precise − highest accuracy enables gentle, nearly pulsation-free pumping action.

  • Large rotor sealing surfaces and the highest accuracy down to the last detail minimize backflow of the fluid inside the pump chamber
  • Gentle pumping of the medium due to flow-optimized inlet and outlet openings
  • Durable, maintenance-free timing gear

Efficient − best performance and highest energy efficiency.

  • Energy savings due to perfect adjustment of the pump casing to the flow-optimized rotors
  • Effective rotor geometry allows most improved fluid dynamics
  • Lowest life cycle costs

The Pump for Conveying Challenging Media.

Customized production and extensive utilization.

Every ONIXline rotary lobe pump is configured for each specific application. The large selection of materials offers the highest adaptability.
The large-volume sealing area allows the use of various sealing systems. The pump casing is equipped with integrated porting for mechanical seal piping plans.
Therefore, the pump can be used for conveying a wide variety of media in diverse industrial markets.

The pump solution for almost every market sector.
