Model: 66M3X0-XXX-C
217 GPM (821.3 LPM)

Features

  • Ideal answer to big volume applications where performance is a must
  • Reliability - Patented "unbalanced" air valve eliminates stalling and freezing
  • Serviceability - Easy access to ball checks and fluid caps for easy maintenance and repair
  • Versatility - Comfort grip handles allow maximum portability
  • Solids Handling - Capable of pumping semi-solids and solids up to 1" (25.4 mm)
  • Screened Inlet - Keeps unwanted debris out of the pump
  • Intrinsically Safe - Pneumatic operation provides safe use in hazardous and explosive applications
  • Power Suction Lift - Designed to evacuate liquids and solids out of critical areas without fail
  • Typical Applications - Mining, construction, and general industrial dewatering and solids handling applications

Pit Boss Dewatering Pumps for Tough Projects

  • This line of air operated diaphragm pumps was developed especially for mining, construction, sump and other operations where a reliable, portable de watering and solids-handling pump is an everyday requirement. These dewatering pumps were named the “Pit Boss” for its tough, uncompromising performance and construction.
