Viscount 2-Ball Pump  Hydraulic Piston Pumps

Hydraulic powered piston pumps for factory and outdoor operation

Where to BuyRequest Info

The rugged pump lower construction with Severe Duty rods and cylinders reduces downtime and extends the interval between repairs. The simple construction makes service and repair fast and easy. The efficient hydraulic power makes these pumps the ideal choice for factory and outdoor mobile use, even at below freezing temperatures. Models include Viscount I 1000 and 3000 and Viscount II 1000, 2000, 2600, 4500 and 5000.

  • Clean, quiet operation with no airborne contamination
  • Up to three times more energy efficient than comparable compressed air systems
  • Positive displacement, 2-ball piston design provides uniform and easily controlled delivery
  • Reduce routine maintenance and cut repairs time in half of comparable pump lowers
  • Eliminate downtime without ice build-up
