Application
Technical center pump
The technical center of a chemical company uses a Börger mobile pump for conveying aqueous solutions, solvents and fatty acid methyl esters. The Börger control technology controls and monitors the entire mobile unit. The unit is operated by means of an operating device at the ATEX-compliant control cabinet. In order to use the mobile pump in potentially explosive atmospheres of the technical center according to ATEX directives, various measuring instruments monitor several parameters of the pump and drive. The duplex stainless steel pump is equipped with double-acting mechanical seals. The seals are pressurized by means of a thermosiphon system. A circulation pump pumps the barrier fluid of the seals into the thermosyphon vessel. Here, the barrier fluid is cooled using an internal cooling coil and the temperature is dissipated via a heat exchanger. The seals are cooled. The up to 150°C media must not cool down during the pumping process. For this reason, the rotary lobe pump is equipped with a steam heater cover. It heats the pump casing. This way, the medium maintains the desired temperature during pumping. The pump is driven by an ATEX-compliant 3.2 kW variable speed motor. The pump speed and the flow rate can be varied continuously between 0.7 and 5 m³/h by means of a hand wheel. This way, the flow rate can be adapted to the specific test procedure.

Pump for conveying lecithin
A German oil mill uses a Börger ONIXline rotary lobe pump for conveying a mixture of lecithin, water and bleaching earth. Lecithin is extracted from the raw vegetable oil in the degumming process by means of a separator. The up to 90 °C hot lecithin mixture is transported to a storage tank. The Börger ONIXline pump conveys the mixture with a viscosity of up to 5,000 mPas in a 35 m high tank where it is inserted by means of nozzles. In the process, a pump pressure of approx. 10 bar is created. Animal feed is produced in the tank. For this purpose, the oil mill uses the press cake which as been separated from the rapeseed. The press cake is enriched with the lecithin mixture. More or less of the lecithin mixture has to be added depending on the liquid content of the press cake. The pump is driven by a frequency converter. This way, the speed and flow rate can be varied and adapted to the liquid content of the animal feed. The bleaching earth contained in the lecithin mixture is the reason why the medium is abrasive. A stainless steel casing protection protects the pump from wear.

Powerfeed connect for feeding biomass into a biogas plant
An operator of a biogas plant has been using a solids dosing feeder for feeding the biomass into the fermenter for several years. The operator was looking for an alternative feeding technology due to the extension of the biogas plant and the very high agitating effort. The operator opted for a Börger Powerfeed connect. The liquid feeding technology can be used for feeding tanks of any number. In addition, they were able to use the existing technology to a large extent. The biogas plant operator is very satisfied with the Powerfeed connect. The customer was particularly impressed by the ease of operation, the trouble-free operation and the long service life. In addition, the agitating effort in the tanks has been significantly reduced and the gas yield has been increased.

The auger [2] rotates in the wedge wire screen [6]. The liquid phase
flows through the screen to the liquid outlet [7]
The auger conveys the solid phase into the press channel [3].
A plug is formed here.
The rotating Multi Disc [4] seals the press channel. When
the desired solid content has been reached, a
small gap opens and the solid phase is discharged.
The Easy Shift unit determines the pre-tension of the Multi Disc.

• The Rotorrake has been redesigned
• Instead of the 18 rotating blades used
so far, 9 blades will be installed on the
hexagonal shaft in future
• With 16.5 mm, the blades are twice as
thick as the blades previously used
• The quantity of the counter blades is
the same
3
• For an even longer service life, the
mounting of the counter blades got a
new design
• The new mounting unit is integrated
into the new casing
• One of the benefits is that the flow
properties are better due to the new
position of the mounting

• In some cases, fibers formed deposits at the mounting in the old version; the rotating blades hit
against these deposits; damage in the shape of rounding at the hexagonal shaft occurred in
individual cases due to heavy braking
• In the new version, the mounting is not positioned in the casing chamber any more; the rotating
blades do not get in contact with deposits at the mounting any more
