Dry Running Vacuum pumps for extrusion

Busch Vacuum Pumps and Systems has successfully introduced their dry vacuum technology for clay brick extrusion to the African market with 13 local installations (including five market leaders). Although the capital outlay on the Busch system is higher than traditional liquid ring systems, clients can expect a return on investment of under 12 months due to energy savings, quicker drying, better brick quality and reduced waste.

The New Technology -  Rotary Vanes

Liquid ring vacuum pumps are associated with high costs in energy, water and pump downtime and maintenance. The Busch dry running vacuum pumps achieve a 0,1 mBar absolute vacuum versus 33 mBar on liquid rings.  These significant improvements in vacuum levels are associated with savings in utility costs.

The Results Achieved

In many cases, savings are greater than anticipated because the existing liquid ring vacuum system is inefficient.

  • Better vacuum performance of 1.5 to 3 kPa
  • Energy savings 20% - 30% versus liquid ring pumps technology. (Far smaller motors)
  • Zero water costs
  • Reduction in waste of +2% due to improved density and break strength of the bricks
  • Helps with ISO14001 and other certifications.

Apollo Brick in Gauteng installed Busch vacuum pumps in 2015 and soon after invested in them as a permanent installation.

“These pumps enhanced our quality standard on column hardness. It increased our vacuum measurement by 2-3 kPa leading to a reduction in green waste. The ROI through waste reduction is obvious. This technology is energy friendly, compact and requires little maintenance compared to the polluting liquid ring pumps. The sales and after sales service of BUSCH is GREAT.”
