Wet Prime Pumps

ES, P and PE Series

Pioneer self-priming pumps are designed for reliable solids and clear liquids handling. After initial priming, they continue to reprime automatically.

  • Rely on the best materials — Standard heavy-wall ductile iron volute and 17-4 PH stainless steel shaft for durability and peace of mind.
  • Get peak performance — A simple external shimless impeller adjustment means the user can easily adjust the tolerance between the impeller and wearplate.
  • Trust our seals — Cartridge type tungsten vs. silicon carbide mechanical seal makes for ease of maintenance and simple installation.

Wet Prime Centrifugal Pump

The Pioneer Pump® GT Series is a robust pumping solution for nearly any food processing, wastewater
treatment, waste handling, chemical processing, or industrial application with high performance
demands. Available in 3x3, 4x4, and 6x6 sizes, they feature a unique shaft design that permits maximum
flow rates up to 2250 gpm at a maximum head of 250 feet with a solids handling capability of up to
three inches. A unique suction spool increases the inlet diameter and alleviates abrasion wear on the
pump, while its distinct cover combines both the fill access cover and flapper valve access cover in one to
improve ease of use – making these pumps ideal for the toughest tasks, all within a standard footprint.
