Use cases
Suitable for universal use
Börger vertical pumps can be used in various ways.
Please find some use cases here.
Tar pits
Tar pit
Highly viscous sludge deposits had to be removed from a tar pit. The problem with the pump systems already in use was the fluctuating viscosity of up to 50,000 mPas due to the temperature and the sometimes very large particles contained in the sludge. Both these factors kept causing the pumps to block.
The solution was the Boerger double-pack consisting of a Multicrusher and a Rotary Lobe Pump. The two units were combined in one frame and both operated using a single hydraulic motor. The entire unit is ATEX compliant and is operated immersed in the pit.

Fuels, oils
Fuels, oils
A customer from the oil and gas industry was looking for a high performance long-shaft pump. Due to the extreme weather conditions in winter, the customer wanted a pump which could be installed in a tank two to three meters underground. The customer decided on a long-shaft version of a Börger Rotary Lobe Pump.
The pump is completely underground and fitted with a customized long-shaft coupling between the pump and the drive. Compared with a similarly constructed pump system, the advantage is that the long-shaft coupling was separated from the medium. The individually pressurized condensate tank is a special feature as it required a solution for the connections to the assembly plate.

Oil-water mixture with shares of wax
Oil-water mixture with shares of wax
An international oil concern was looking for a pump to convey a oil-water mixture in a Gas-To-Liquid Plant (GTL). The oil-water mixture arises as byproduct in the production process and should be transported to its‘ further use.
The customer decided in favor of a Börger rotary lobe pump. The high quality of the Börger Rotary Lobe Pumps as well as the good experience made with Börger pumps as sump pump convinced the customer.
For the GTL plant, they decided in favor of an execution as submerged pump. This execution is also able to transport the shares of wax, which partly build up in the highly viscous medium.
The customer is very satisfied with the Börger rotary lobe pump. Above all the possibility to produce the pump according to the customers’ wishes convinced the customer.

Submerged pump for grease sludge
Submerged pump for grease sludge
A waste water treatment plant had persistent problems with a centrifugal pump which was used for pumping grease sludge. The submerged centrifugal pump pumped the sludge from the grease sludge basin into a storage shaft from which a second pump fed a digestion tower with the grease sludge. Higher TS contents caused problems to the centrifugal pump. The recurring blockages of the pump and the complex maintenance work resulting from them were the reason why the operator of the waste water treatment plant looked for an alternative pump technology.
Following intensive research, the customer decided to purchase a submerged Börger rotary lobe pump. Due to its ability to pump with stable pressure, the Börger rotary lobe pump can convey the viscous grease sludge from the grease sludge basin into the digestion tower directly. A storage shaft and a second pump are not necessary any more.
The customer is very satisfied with the new grease sludge pump. Since the customer has been using the Börger rotary lobe pump there have not been any failures caused by the pump even with high TS contents of the pumped medium.
