Hellbender DAF Pumps 
  
 

What is It?

  
The Hellbender DAF Pump is the new standard for DAF recycle pumps. It is specially designed to be used in dissolved air flotation systems, which are used to remove solids, oils, and greases from water, wastewater, and other waste streams.

The Hellbender DAF Pump is different from a regular centrifugal pump.

  • It is specially designed to operate at high (~100 psi) pressures and pump water with entrained air without cavitating.

  • It is capable of achieving 100% of theoretical air-in-water saturation.

  • It achieves higher air dissolving efficiency compared with standard centrifugal pumps, due to high pressure and unique design.

  • It efficiently shears incoming air into small bubbles, allowing for large amounts of air to be entrained in, and later dissolved in, the water.

 

Features of the Hellbender DAF Pump
  

  • Simple single-stage, single-impeller design

  • Reliable, long life

  • Available in bronze-fitted or all-bronze models

  • Supplied with mechanical seals and rugged Baldor motors

  • Superior whitewater production with very fine bubbles

  • Available as a replacement recycle pump for existing DAF systems, or can be packaged as part of a complete whitewater system for gravity settler/skimmer retrofits.

The Hellbender DAF Pump vs. other DAF pumps
  

  • Made in the USA

  • Pumps and parts in stock for quick delivery

  • Enclosed impeller allows for greater solids handling capability than other DAF pumps

  • Replaceable wear ring prevents erosion of pump casing due to high velocities in suction area of pump

  • No intake throttling required, eliminating cavitation due to throttling and extending pump life

  • Single impeller reduces capital and maintenance costs and simplifies maintenance

  • Can be used either with an eductor loop or with a compressed air source

  • Application assistance from highly-experienced technical staff

  • Close-coupled, eliminating the need for alignment and an external coupling and baseplate

  • Compact footprint
