Wet Prime Pumps

GS 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.
