Features and Benefits

The Wilden® bolted metal pump, also known as FIT, sets the new standard for pump performance. Featuring an enhanced flow path design, Wilden's bolted-construction pumps offer improved flow rates (up to 35% over competitive models) as well as improved diaphragm life. Wilden's bolted pumps are also designed for superior containment and have the exact bolt down footprint and inlet/discharge connections as Wilden clamped pumps for easy replacement.

  • NPT or BSPT threaded inlet/discharge liquid connections (PS220)
  • DIN or ANSI flanged inlet/discharge liquid connections (PS230) that don't require welding or nipple attachment
  • Featuring the energy-efficient Pro-Flo® SHIFT ADS
  • Greater flow - more gallons pumped per SCFM
  • Reduced air consumption and kilowatt usage
  • Largest chemical compatibilities
  • Portable and submersible
  • Large-solids passage
  • High suction lift
  • Ease of operation and maintenance
  • Flexible internal adjustment on manifolds
  • Increased on/off reliability
  • Longest Mean Time Between Repair (MTBR)
