B-500 Bentonite Mixing Systems


The B-500 by American Augers is a high capacity bentonite mixing system that was specifically designed for the auger boring contractor. The standard unit is equipped with a low pressure diaphragm pump that delivers mixes at 14 Gallons (52.99 L)/per minute @ 200 PSI (14 bar), 515 RPM. Uses the bentonite to modify sticky soils into more manageable ground conditions.

Standard Features

  • 9.5 HP (7 kW) Diesel Engine
  • 500 U.S. Gallons (1,892 L) Tank

Additional Benefits

  • Reliably delivers the bentonite slurry to the lead casing under pressure to reduce friction and will produce a 5% gel concentration in 500 U.S. Gallons (1,892 L) of water, but if soil conditions are very porous (mostly gravel etc.) a thicker gel may be used.
  • Lubricates and supports the pipe while penetrating the soil
  • Assures better grade
  • Improves thrust capabilities
  • Retards sloughing and cave-ins
  • Extends equipment life
  • Speeds up jacking operation
  • Can be used as a pressure washer during clean up time, or for pressure-testing of water lines
