Rotary Lobe Pumps – as individual as your application
No matter if stationary, mobile or submerged, all pump components are selected individually according to the requirements of every single application.
With our two series of BLUEline and ONIXline, the portfolio of 25 pump sizes with flow rates of 4.4 – 7,050 usgpm (1 and 1,600 m³/h) and pressure stabilities of up to 232 psi (16 bar), Börger can offer the perfect pump for every single application.
Börger Rotary Lobe Pumps are self-priming , valveless, positive displacement pumps. The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.
Two convincing product series
The BLUEline rotary lobe pump is our proven “continuous runner”. 21 pump sizes and the large selection of materials and rotors (different geometric designs and materials) allow an individual design of the pump adapted to your application.
The ONIXline rotary lobe pump is the flagship of our pump range. The newly developed rotors in a flow-optimized pump casing in combination with the very robust carrier and timing gear ensure the best efficiency even with high pressures. The ONIXline offers the highest flexibility when selecting the sealing system.
