Viscount II 1200 and 3100 – Hydraulic piston pumps

The hydraulic piston pumps Viscount II 1200 and 3100 are ideal for letterpress and lithographic inks.

When paired with any of Graco’s priming piston pumps, the Viscount II hydraulic air motor offers exceptional cost savings by operating on 20% of the energy used by a pneumatic motor. The Viscount II, Graco’s patented hydraulic motor, replaces the King, Bulldog or Senator motors with the 800 or 2100 pump.

Product features

  • Clean, quiet and efficient hydraulic power
  • Extremely durable hydraulic pump with long-life packing design
  • Highly efficient Viscount hydraulic motor reduces energy costs
  • Stainless steel wetted parts with neoprene packings

Hydraulic or Pneumatic?

Graco offers both hydraulic and pneumatic motors to drive your priming piston pump. Both are top quality choices for smooth,
