Boerger doesn’t compete on price, but on performance. This is epitomised by the company’s rotary lobe pump range.
As cost and sustainability pressures grow, industrial facilities are having to adjust their operations to improve efficiency, lower energy consumption, and reduce downtime – all while handling increasingly demanding pumping applications.
Whether in wastewater treatment, biogas production, chemical processing, food manufacturing, mining, or emergency response operations, pumping equipment is being called on to deliver reliable performance under a range of operating conditions.
Among the many pump systems available today, rotary lobe pumps have earned a reputation as one of the most versatile and dependable solutions for modern industry. Their ability to handle everything from low-viscosity liquids to highly viscous, solids-laden media has made them a preferred choice for engineers and operators worldwide.
As industries evolve, so too has rotary lobe pump technology. Manufacturers such as Boerger have continually refined their designs to improve efficiency, simplify maintenance, and deliver application-specific solutions that meet the diverse needs of modern operations.
“Industrial pumping applications rarely operate under ideal conditions. Fluids can vary significantly in viscosity, solids content, abrasiveness, and chemical composition,” Dominik Straetling, managing director of Boerger Pumps Asia, Singapore, told Pump Industry.
“Pumps must therefore be capable of adapting to changing process requirements without sacrificing reliability.”
Rotary lobe pumps achieve this through a simple-yet-effective operating principle. Two synchronised lobes rotate within the pump housing, creating cavities that transport the pumped medium from the suction side to the discharge side. This positive displacement action ensures a consistent flow rate while providing gentle product handling and excellent solids capability.
The result is a pumping solution capable of handling sludge, wastewater, chemicals, oils, food products, polymers, digestate, and many other challenging media with exceptional reliability.

Looking beyond the purchase price
When selecting pumping equipment, focusing solely on the initial purchase cost can be misleading. Operators are instead best placed to look at the total cost of ownership, which provides a more holistic view of energy consumption, maintenance requirements, spare parts costs, and operational downtime.
“Modern rotary lobe pumps are increasingly valued for their ability to minimise these ongoing expenses.” Straetling said. “Efficient hydraulic design reduces power consumption, while robust construction helps ensure dependable operation over many years of service.
“For plant operators, the greatest value often comes not from the pump’s purchase price, but from its ability to deliver reliable performance day after day with minimal interruption.”
One of the most significant contributors to operational cost is unplanned downtime. Every hour spent servicing equipment can affect productivity and profitability.
This is why maintainability has become a key consideration in pump design. Boerger’s Maintenance-in-Place (MIP) concept allows wear components to be accessed directly through the front cover without removing the pump from the piping system.
“This approach significantly reduces service times and enables maintenance personnel to perform inspections and component replacements quickly and efficiently,” Straetling said. “For facilities operating continuously, the ability to minimise downtime can provide substantial operational and financial benefits.”
The BLUEline Legend and BLUEline Nova
For many industrial users, reliability remains the most important performance consideration.
The BLUEline Legend series represents Boerger’s proven rotary lobe pump technology, refined through decades of practical operating experience. Designed for durability, efficiency, and ease of maintenance, these pumps have become trusted solutions across municipal, industrial, and commercial applications worldwide.
“From wastewater treatment facilities and sludge handling systems to industrial process duties and mobile pumping applications, the BLUEline Legend provides dependable performance in demanding conditions,” Straetling said.
“Robust construction and service-friendly design make this rotary lobe pump a preferred choice for operators seeking long-term reliability and low lifecycle costs.”
From the success of BLUEline Legend, Boerger has continued to pursue new ways of unlocking greater operational efficiency and sustainability, driven in large part by customer needs.
This has inspired the BLUEline Nova – a novel solution to meet modern industrial requirements.
Featuring an advanced hydraulic design, the BLUEline Nova optimises flow characteristics while maintaining the durability expected from Boerger rotary lobe pumps.
“By reducing energy consumption and enhancing overall pumping performance, the BLUEline Nova helps operators achieve lower operating costs and improved process efficiency,” Straetling said.
“It represents the next step in rotary lobe pump innovation, helping facilities eager to achieve sustainability objectives while not compromising on performance.”

The ONIXline
Not all pumping applications are created equal. Some involve highly abrasive sludges, aggressive chemicals, viscous products, or extreme operating conditions that demand exceptional durability.
The ONIXline series has been engineered specifically for these demanding environments.
Its advanced design enables it to handle challenging media while maintaining reliable performance. For industries such as mining, wastewater treatment, chemical processing, and heavy manufacturing, the ONIXline offers a robust solution where reliability is critical and downtime isn’t an option.
The strength of Boerger’s rotary lobe pump range lies in its ability to provide specialised solutions while maintaining the core advantages of rotary lobe technology.
Whether selecting the proven reliability of the BLUEline Legend, the enhanced efficiency of the BLUEline Nova, or the heavy-duty capabilities of the ONIXline, operators benefit from a common commitment to quality, serviceability, and long-term performance.
These benefits align with the future of fluid handling, where the need for greater efficiency and reliability is more important than ever. This will see technologies that minimise energy consumption and simplify maintenance increasingly prioritised in industrial applications, placing Boerger – which competes on performance, not price – at the front of the queue.
