Performance curve

High flow rate even with increasing pressures

Pump performance curves provide information about the efficiency of a pump. The flow rates of Börger rotary lobe pumps remain virtually constant even in case of increasing pressures.

The ONIXline rotary lobe pump series at a glance:

Pump series Min. flow rate in usgpm Max. flow rate usgpm Max. pressure in psi
ONIXline BJ 090 12.00 190.00 232
ONIXline BJ 140 18.50 296.00 190
ONIXline BL 190 25.00 401.50 232
ONIXline BL 280 37.00 592.00 190


*The maximum speed and maximum pressure are different depending on the pumped medium. Please ask for order-related data.
