Centrifugal Gravity Separators

Auxill Gravity Separators are solids removal devices which rely on centrifugal force and specific gravity of solids for efficient operation. The tangential inlet and the special spinfex construction in the top dome of the separator guarantee the optimal centrifugal action, required to achieve efficient and continuous separation.These separators are used for the removal of unwanted, heavier solids in all processes. Centrifugal force and gravity separate sand, rust, scale, metal and other bothersome solids from liquid and process streams. Solids are concentrated for easy and efficient removal, with limited water loss.

Benefits

  • Low pressure drop
  • No moving parts
  • Continuous filtering
  • No filter media
  • Environmental friendly
  • Easy installation
  • Low maintenance costs
  • High Efficiency
  • Closed system
  • Automatic purging possible

Applications

  • Source water intake
  • Washing operations
  • Fire fighting systems
  • Coolant filtration
  • Desanding
  • Pump protection
  • Pre-filtration
  • Waste water upgrading

Installation

Installation of the Auxill Centrifugal Gravity Separator is very simple. The separators can be placed both in-line and side-line. The large separators can be placed in 25º to limit required installation height.

Operating principle

The liquid enters the unit tangential, which creates a centrifugal flow. A special top inlet construction accelerates the centrifugal flow. Centrifugal force moves particles to the side of the separator chamber. Solids slowly drop along the side to the quiet collection chamber. Cleaned liquid is drawn up through the vortex and leaves the separator by the top outlet. Solids are either periodically or continuously purged from the collection chamber.
