BÖRGER Blue Line
World's best-selling industrial lobed rotary pump in a robust and highly service-friendly design. Quickly interchangeable rotor tips and liners in the pump casing significantly reduce operating costs compared to conventional pumps.
Suitable for viscous and abrasive media
Even the most viscous and abrasive media can be pumped.
Powerful self-priming and capable of dry running
The pump is highly self-priming and can withstand dry running for short periods.
High capacity, reversible and compact dimensions
BÖRGER lobed rotary pumps are characterized by an incredibly high capacity, even with viscous media.The pump's compact design and reversible capability make it particularly suitable for installation on e.g. trucks where space is limited.
Flexible and service-friendly design
A multitude of rotor and shaft seal types, combined with numerous material qualities, ensures the best possible pump configuration!
Countless configuration options
BÖRGER lobed rotary pumps can be configured for virtually any medium. Thanks to the many materials, rotor types, and shaft seal types, optimal service life is achieved, even in very challenging pump tasks.
VarioCap - pressure relief valve
All Börger Blue Line pumps can be supplied with VarioCap pressure relief valve to protect the pump from overpressure.
- Pressure relief valve integrated in front cover
- Non-clogging (No need for Bypass)
- Protects pump and piping system from overpressure and pressure surges
- Available in steel or stainless steel
The following videos demonstrate the service-friendly design of the Börger pump
Rotor tips are replaced individually. If one or two tips are defective due to foreign objects, only the defective tips are replaced.
The pump casing is protected with wear plates and liners made of a durable material. Disassembly to replace the pump casing is no longer necessary.
The front-mounted mechanical shaft seals are easily and quickly replaced from the front. Disassembly of the pump is not necessary.
Fully rubber-coated rotors can be replaced in minutes using a simple puller.
Wide range of shaft seals for every industry
The Blue Line series comes standard with single mechanical shaft seals with oil lubrication/cooling. As an option, the pump can be supplied with double mechanical cartridge seals. Sliding surfaces and gaskets in numerous combinations, depending on the fluid. Most of the seals are ATEX compliant.
Protecting the pump & process against overload
Adjustable pressure relief valve
The adjustable pressure relief valve is mounted in the pump's front cover. The valve protects the pump, regardless of direction of rotation. The valve is available for all construction sizes and is supplied in cast iron or various types of stainless steel.
Eliminates traditional by-pass systems
The integrated pressure relief valve eliminates traditional by-pass systems, which are at risk of blockages and require significantly more space.
