This versatile pump handles limited fibrous waste. The impeller blades’ swept-back design increases pumping efficiency for high-volume flow through the 4-inch (101.6 mm) steel tube.

  • Pumping capacity up to 1,580 gals./min (5,981 liters/min.).
  • Available in lengths to fit your application: 6 ft. (1.8 m), 8 ft. (2.4 m), 10 ft. (3.0 m), and 12 ft. (3.6 m)
  • A 16-inch (40.6 cm) Impeller for added capacity.
  • Variable agitation capacities with a standard dual agitation system.
  • Abrasion-resistant steel in high wear areas for longer life.
  • Versatile – can be used in a variety of applications: Agitate a pit, Move from short-term to long-term storage, Load tankers/spreaders and separators, Transfer wastewater
  • Tapered-bore drive pulley mounts to a 1-3/4 inch (44.5 mm) drive shaft with a greaseable flange bearing at the top of the drive tube.
  • Easy access to oil reservoir. End guessing! Inspect oil level conveniently in transparent oil line at top of pump. A large fill hole allows easy access for adding oil to the drive tube. Patz recommends using a non-detergent oil.
  • High-volume delivery. The voluted design of the impeller housing and the curved blades increase pumping efficiency.
  • Protection against bearing contamination. The lower bearing’s oil-bath chamber has 3 seals to keep contaminants out. No sleeve bearings to wear out fast.
  • Clogging prevented and positive input provided. Shear plate located close to the impeller to help prevent clogging and provide positive input.
  • Lifting loops located on top of the pump allows easy insertion and removal of the unit from the pit with a tractor loader, skid-steer loader or winch.
  • A steel mounting plate is included as standard equipment to allow precise positioning of the pump to match the pit depth. Plate can be lagged to a concrete pad or curb.
  • Pump available in various lengths to fit pit depths of 5 ft. 6 in. (1.7 m) to 12 ft 10 in. (3.9 m).
