  • Lightweight and compact design
  • Durable glass-filled nylon reservoir and nylon encapsulated aluminum pump base for maximum corrosion resistance
  • Two-speed operation on most models reduces handle strokes by as much as 78% over single-speed pumps
  • Lower handle effort to minimize operator fatigue
  • Handle lock and lightweight construction for easy carrying
  • Large oil capacities to power a wide range of cylinders or tools
  • Non-conductive fiberglass handle for operator safety
  • Internal pressure relief valve for overload protection

Think Safety

Manufacturer’s rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!
