1. Raw Sewage - Lift stations, CSO facilities, headworks, prisons, hospitals, restaurants.
2. Screening / Septage - Raw concentrated solids including rags, plastics and hair.
3. Clarifier Scum Pits - Primary or Secondary scum without plugging or air binding.
4. Sludge Transfer - Eliminates "roping" and clogging in clarifier underflow to thickeners.
5. & 6. RAS / WAS - Continuously conditions Return and Waste Activated Sludges.
7. & 8. Thickened Sludge / Digested Sludge Transfer - Handles high sludge consistencies.
9. Digester Mixing - Rotamix® system conditions and mixes in a dual-zone rotational flow pattern.
10. Digester Recirculation - Eliminates heat exchanger clogging while conditioning sludge.
11. F.O.G - (Fats, Oils, and Greases) - Uses organic waste to enhance methane production

With over 40 years of pump experience and in excess of 20,000 pump installations, Vaughan has proven technology in long term, low maintenance and the highest reliability of any chopper pump. The patented chopping action of the cupped-and-sharpened impeller blades chops and conditions all incoming solids, eliminating pump and piping plugging. Vaughan’s unique features necessary to provide this reliability include:

• Patented chopping design
• Wear parts heat treated to extend pump life
• Oversized shafting and bearings
• Heavy duty mechanical seals
• Adjustable back pull-out design

• Almonds
• Blood
• Carrots
• Chickens & Turkeys
• Corn Husks, stalks
• Ears, Hair, Hooves, Horns
• Fat
• Feathers
• Fish Offal
• Fleshings & Hide Pieces
• Onions
• Peppers
• Pomegranates
• Potatoes
• Tomatoes
• Washdown sumps

• Oil-filled bearing housing
  Increases bearing life
• Seal-and-bearing sub-assembly
  Reduces maintenance time
• Ductile iron casing and bearing housing
  Increases durability
• Double-row thrust bearings
  Absorb all impeller loads
• Vaughan’s cartridge style silicon carbide mechanical seal
  Protects bearings and lasts longer
• Pump-out vanes and upper cutter
  Keeps pumpage away from seal
• Cast alloy steel impeller, cutter bar, upper cutter and cutter nut
  Case hardened to minimum 60 Rockwell C hardness for wear and impact resistance
