No matter if stationary, mobile or submerged, all pump components are selected individually according to the requirements of every single application.
With our three pump series BLUEline Nova, BLUEline Legend and ONIXline in 25 pump sizes (flow rates of 1 to 6,400 usgpm (1 to 1,440 m³/h), a large selection of equipment and additional parts, we are able to build rotary lobe pumps that are perfectly suited to every single application.
Construction
Sophisticated quality down to the last detail
Börger Rotary Lobe Pumps are cleverly designed down to the last detail. This ensures very long service lives. The large seal chamber provides space for almost any sealing system. The oil-filled intermediate chamber protects the gear unit. The quench fluid cools and lubricates the seals.
The pumps are very easy to maintain thanks to their MIP® (Maintenance in Place) design. All wear parts can be replaced in a matter of minutes through the quick-release cover of the pump.
Operating principle
Pumping liquids simply and efficiently
The synchronized rotation of the rotor pair creates a vacuum on the suction side of the pump. This vacuum draws the liquid into the pump chamber.
The medium is pumped into the pressure area due to the rotation of the rotors. If the direction of rotation is changed, the flow is reversed.

- High-performance pumps
- Large variety of rotors
ONIXline
- Flow rates of 1 to 135 m³/h
- Pressure-resistant up to 16 bar
- Maximum choice of sealing systems
There's no such thing as expensive maintenance contracts at Börger. You take charge of maintenance and repairs yourselves! The unique MIP® system for our pumps makes it easy. MIP® stands for “Maintenance in Place” meaning that all worn parts can be easily replaced by maintenance staff directly at the installation site without dismantling any pipe or drive systems.
Due to the cantilevered carrier design of the pump, the wear parts stressed by the pumped media can be replaced through the quick-release cover of the pump.
Benefits
We build pumps suited to your needs
Every single Börger pump is a customized solution. We are unrivaled in our selection and variety of material. In addition, the pump unit is completely designed to meet the specific requirements of the application. Whether it is a mounted drive, a submersible mode, or a mobile pump on a tanker truck, our pumps are as unique as your needs.
Perfectly suited for any viscosity
Regardless of whether the pumped liquid has aqueous or highly viscous flow properties, this is no problem for our rotary lobe pumps.
The pump speed is reduced for conveying highly viscous fluids. Thanks to its flexible speed, the pump can be used for conveying low and highly viscous media.
Unique quality
Each rotary lobe pump is equipped with a non-segmented pump and gear casing. This design reflects our high standard of quality and guarantees a long service life with ease of maintenance.
The pump casing can be manufactured in cast iron, cast steel, stainless steel, duplex steel or Hastelloy®.
ATEX, API and NACE
For use in potentially explosive atmospheres, pump units often have to be manufactured according to the European ATEX guidelines (2014/34/EU). We manufacture ready-to-connect, ATEX-compliant, stationary, mobile or submerged pump units exactly in line with your wishes and requirements.
For the application of pumps in the oil/gas and petrochemical industry, very often requirements according to the American Petroleum Institute (API) and the National Association of Corrosion Engineers (NACE) must be complied with. Börger pumps can be designed in compliance with the requirements according to API 676 for displacement pumps, API 682 for seal types and the corresponding supply systems and the materials requirements according to NACE 0175 + 0103.
For more information on our ATEX-compliant rotary lobe pumps please refer to our Brochure.
TA-Luft
The technical guideline for air quality control is the German government's “first general administrative regulation under the federal air pollution control act”.
Under the Air Pollution Control Act only technically sealed pumps, valves and seals with leak rates in accordance with VDI 2440 may be used for pumping certain toxic media.
Börger provides solutions for the lawful use of toxic and highly toxic media throughout its product range according to the Air Pollution Control Act.
Börger rotary lobe pump designs
- Large variety of options thanks to intelligent pump control
- Flexible adjustment of the flow rate via motor control with frequency converter, which allows versatile use of the pumps
- Highest level of safety due to dry run protection, pressure and temperature monitoring of the pump
- Simplified operation thanks to automated fill level control
- External control by operator possible via mobile communication, WLAN, DSL (remote maintenance by Börger is also possible)
- User-friendly manual switchgear with right-hand/left-hand running and start/stop command
- Complex regulation of various functions with PLC
- Simple entry and user administration via touch display
- and so on
Oil-filled intermediate chamber
The oil in the quench chamber cools and lubricates the seals.
The intermediate chamber protects the gear unit from pumped medium leaking in if the seal is defective. and ensures the highest degree of safety.
The liquid in the quench chamber can be specified according to the pumping task, e.g. food-grade oil.
Material variety
Each Börger rotary lobe pump is configured and produced for its specific application. Every component is available in many different versions.
Using a modular principle, each component of the pump is selected so that it is ideally suited to the requirements of the respective application with regard to its material properties. This ensures very long service lives.
In-house pump testing facility
An in-house testing facility is used to subject new products to realistic conditions. In addition, quality assurance controls and individual tests are performed for the customer in the Börger pump testing facility.
- 9 m deep suction shaft (17 m³)
- 34 m³ tank capacity
- Various pipe sizes
- Comprehensive measuring instruments
- Automated visual display of the test results
- High-temperature test stand for fluids up to 300 °C
