Viscount II 1200 and 3100
Hydraulic Piston Pumps
Hydraulic piston pump 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.
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
