Agitator technology


Submersible Mixer

Effective agitation

The B-MX submersible mixer ensures that liquid media with solids are mixed reliably and effectively.

The Börger mixer impresses thanks to its slim shape, which ensures optimal flow behavior.

Effective substrate mixing

With its aerodynamic blades, the Börger B-MX is installed in a tank filled with liquid or in a liquid manure channel. The rotation of the mixer blades ensures that the fluid is circulated, including the solids it contains. Thick floating layers and heavy sediment are stirred.

The ultra-slim design and smooth surface of the whole submersible mixer allows liquid to flow to the displacement blades without creating turbulence. This guarantees high efficiency.

Construction of the B-MX

The submersible mixer has an aerodynamic design. The liquid flows to the displacement blades without turbulence. This allows optimal use of the supplied energy.

The agitator blade of the B-MX consists of two rotor blades which are designed in such a way that their rotation produces maximum thrust.

Four different motor outputs can be selected. The oil filling in the motor not only ensures a long service life, but also lubricates the tapered roller bearing.

The system is sealed by a high-quality mechanical seal. A large-volume quench chamber ensures the highest degree of operational safety.

Benefits

Convincing arguments

Flow-optimized design without edges

The slim design of the B-MX and the geometry of the agitator blades have been optimized using the latest flow simulation programs and ensure lowest energy input at maximum efficiency.

Quality down to the last detail

The high-precision block casing is made of stainless steel.

All wetted parts are manufactured from stainless steel.

Sophisticated design

The three-phase drive is supplied through a connection cable by a cable inlet which is permanently closed but changeable (at the rear of the B-MX).

By means of the thermal sensor integrated in the coil, the motor is monitored and protected against overload.

The B-MX also agitates your stored liquids effectively

  • Biogas substrate
  • Liquid manure
  • Treatment of digested sludge
  • Primary wastewater treatment
  • Secondary wastewater treatment
  • Homogenization basins
  • Pumping stations
  • Nitrification plants
  • Rainwater retention basins
  • Sludge collectors
  • and much more

Control technology customized for your requirements

Upon request, our electrical engineering department produces and programs a control technology which is perfectly matched to your requirements.

 

  • Fully automatic mixer control
  • Manual and/or automatic operation
  • Semi-automatic time control (Auto Stop)
  • Control of several mixers possible
  • Time control via week timer
  • Star-delta startup
  • and so on

Highest level of safety thanks to mechanical seal and intermediate chamber

The system is sealed by a high-quality mechanical seal. A large-volume quench chamber ensures the highest degree of operational safety.

Optionally, an electronic leakage detector is installed in the intermediate chamber to recognize leaks at an early stage and to avoid consequential damage.

Application options

Perfect for tank circulation or in a circulation system

The submersible mixer can be used to stir substances such as sludge, liquid manure, digestate and animal feed.

Options

Tank circulation

The B-MX can be used for circulation in elevated or underground tanks.

It is connected to the guide rail by means of the guide carriage. The guide rail guides the mixer. Attaching the mixer to the tank wall is not necessary.

The adjustment unit can be used to change the height and the lateral position of the mixer. The B-MX can always be adjusted optimally with changing fill levels, thus ensuring the best possible homogenization of your stored liquid.

At an elevated tank you can reach the adjustment unit very easily via the work platform. From here, you can look into the tank. On request, we manufacture the working platform exactly to your specification.


Dimensions

The B-MX submersible mixer is very compact and powerful and can be retrofitted into existing systems with ease.

Application options

B-MX for circulation systems

The B-MX is also suitable for circulation channels (slalom liquid manure channels).

The submersible mixer sucks the liquid from the side of the motor and pushes it through the mixing tunnel thereby creating a circulation flow.

Case Studies

Practical example

The B-MX is used in many different areas. Please find a small selection here.

Circulation system

In a circulation system a cattle farmer used 3 PTO mixers which were driven externally by the PTO shaft of his tractor.

As part of a barn enlargement the cattle farmer now uses three Börger submersible mixers B-MX. The submersible mixers completely made of stainless steel could be attached to the existing guide rails of the replaced PTO mixers.

Propellers with a diameter of 400 mm (15.7 inch) were selected due to the low space. The submersible mixers are driven by a 9 kW electric motor.

Tank circulation

A farmer had problems with floating layers forming in his liquid manure storage tank. Solids deposited in the tank.

The installation of a B-MX submersible mixer was able to solve the problems. Thanks to the swivel action of the B-MX, the entire tank can be stirred effectively.
