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.

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.

A major chemicals and mineral oil company runs a mixing plant for E5 and E10 fuels. Here the ethanol is fed in doses into a main flow of petrol. The petrol is delivered in tanker vessels. A pump transports the petrol to a storage tank on land from the vessel. Ethanol is added to the petrol on the way to the storage tank (5% for E5 or 10% for E10). The chemicals and mineral oil company requires a pump for this procedure. The customer uses the Boerger Rotary Lobe Pump in an ATEX version.

The ethanol is delivered in tanker vehicles. The Boerger Rotary Lobe Pump draws off the ethanol via a storage tank security wall (3m). To ensure an exact dosage even when the petrol pump output varies, the speed of the Boerger pump is controlled by frequency converter. A magnetic flow meter (MID) measures the amount of pumped petrol. A corresponding control unit regulates the frequency-dependent speed control. This guarantees an exact mixing ratio of ethanol and petrol.

As the air quality control requirements are applicable here, a pressure gage was installed on the pump quench chamber to shut down the pump if pressure fluctuations occur in the quench chamber. PTFE lip seals were also fitted. This ensures the pump is permanently technically sealed in accordance with the air quality control requirements.

Technical data

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.

Technical data

The importance of tankers as means of transport for liquid substances has increased in recent years. Börger rotary lobe pumps are used for emptying the loading arms. These “stripping pumps” must convey reliably and very efficiently as the ships are supposed to depart as soon as possible after they have been loaded or unloaded. The Börger rotary lobe pumps are configured individually according to the specific requirements of the media to be conveyed and the filling station. Thanks to the large selection of pump sizes, rotors and materials of the Börger pumps a suitable pump can be built for each unloading system.

Technical data

A large refinery uses several Börger rotary lobe pumps for pumping out the collecting basins. The surface water of the refinery, which consists of rainwater, production residues and safety overflows etc., is collected in these basins. The pumps were manufactured according to the API 676 for rotary positive displacement pumps in compliance with the customer's requirements. As the Börger pumps can master the required suction height of 6 m without problems, the pumps could be installed above the collecting basin.

Technical data

A mineral oil company uses two Börger mobile pumps for conveying changing media and for "pigging" the pipelines. For use on the premises, the entire pump units including the pump itself, the drive and the control technology are manufactured in ATEX-compliant design. The mobile units including the drive are mounted on base frames equipped with fork-lift openings. The pumps can be transported to the application site very easily by means of a wheeled loader. The 30 kW three-phase motor is connected to a junction box on the premises by means of an extension cable. The pumps are ready for use straight away and convey up to 100 m³/h with a pump pressure of up to 8 bar. 

Technical data

A petrochemical company uses two ONIXline rotary lobe pumps for emptying tank wagons. The pumps with dry-run capability convey methyl tert-butyl ether (MTBE) and 2,2,4-trimethylpentane (isooctane) from the wagons to storage tanks. Due to the high chemical aggressiveness of the pumped media, pump casings were made of stainless steel. The fluids are pumped nearly without pulsation due to the steel rotors with screw profile. All O-rings are made of perfluoroelastomers (FFKM). The self-priming pumps are installed in potentially explosive atmospheres and, therefore, have an ATEX-compliant design.

Technical data

When cleaning up several large oil sludge storage ponds, Börger Rotary Lobe Pumps are used to decontaminate the soil. The sludge and waste pumps are subjected to a maximum temperature of 150°C as processing the soil with oil is done by rotary kilns. No problem for Börger pumps with FPM coated rotors!

Technical data

In a refinery's loading area, two types of Boerger pump are used for petrochemical products. The smaller one feeds barrels and the large one feeds tanker vehicles. The Variocap serves as a mechanical excess pressure protection.

Technical data

The worldwide crude oil operator uses a Börger Rotary Lobe Pump for collecting and transporting a mixture of used oil and waste water from its refinery and tank storage area. In this case, the crucial benefit of the Börger pump  was the the low emulsifying risk.

Technical data

A robust positive displacement pump was required for tank cleaning purposes using "Butterworthing": Oil is sprayed from nozzles as a coating on the tank walls to prevent corrosion. A Boerger Rotary Lobe Pump with diesel motor drive was selected for its robust and easy to maintain design.
