The small subfloor pump

220 Volts freedom

For more than twenty years, BUNKER has developed and made mixers – transporters for floor screed. In fact, using these machines will save you both time and money, doing away with the need for concrete mixers, wheelbarrows, cranes or other types of lifting machinery.
The Tragen B200 pump for floor screed is the smallest in the range. Its originality lies not only in its compact dimensions, making transport and positioning in small building yards easier, but mostly in its reduced actuation power.
A mere 2.2 kW single phase is enough, (i.e. the power in the electricity mains) and the B200 is ready to start working, a possibility that is often denied to superior category machines since not all building yards have enough energy to power them.
The layer knows this only too well!
So it is truly a great advantage, which frees the construction company from tiresome and expensive electricity supply contracts.

Applications

Combined with a 2000 litre compressor you will be surprised by its performance, with just one operator, as it mixes and pumps approx. 8-10 m3 at a height of 30-40 m in a day. The most varied mixes and for floor screed used today in modern constructions:

  • sand, polystyrene, cork, fine gravel

  • concrete with a max granulometry of 20 mm

  • light concretes

without the need for continuous displacements.

Technical Data

A modern machine with a stylish design that inspires safety. The experience gained over years of business and our constant effort in the ongoing improvement of our products have led to the creation of the B200 project: reducing the actuation power to just 2.2 kW without jeopardising performance was a challenge we faced with enthusiasm. See the results for yourselves.

  • 1 – descent block valve
  • 2 – sturdy crane hooks
  • 3 – emergency stop
  • 4 – safety lock
  • 5 – skip actuation lever
  • 6 – air distribution assembly
  • 7 – large-thickness tank
  • 8 – large-diameter wheels for easier transport and positioning at the yard

The electrical panel is protected against knocks and tampering, and allows the operator to control the functions, indicating the status by means of indicator LEDs. The motor comes to an automatic stop should the mobile safety protection guards be opened. The standard hour counter allows for work and maintenance programming.

 

The tank 10 mm thick is designed and tested to resist wear and pressure, purpose designed for delivery piping of variable diameter and fitted with a protective grid that prevents the operator’s hands from coming into contact with dangerous parts. When opened, the mixer blocks.

The tank interior is provided with a wear-resistant coating, the shaft is supported by special bearings and long-lasting perfectly airtight seals. The mixing blades are made of a wear-resistant alloy, and their 20 mm thickness ensures hundreds of working hours.

The quick-closing lid with a balancing valve and a sturdy air release valve is also fitted with a safety device, which prevents it from being opened during operation.

Tragen rapidly mixes the mix loaded manually or by means of a loading skip, then the flow of compressed air pushes it along the piping to the laying site.

With the diffusion of quick-drying screed, the perfect mixing of the binder with the aggregate must be guaranteed in order to obtain the desired result and the chemical combinations necessary to achieve low residual humidity after just a few hours. The agitator blades, their shape and arrangement are designed especially for this purpose.
