Air-Operated Double-Diaphragm 2″ Graco Pumps
A Graco Pump has many applications including Food, General industry and the Motor industry. Handles fluid viscosities up to 5,000 cps and solids up to 0.09 inch (2.29 mm). Easy-out seal provides fast slide in and out of drums (through bung adapter) without disconnecting hoses. Easy-out seal accommodates slightly off-sized drums up to 2-1/2 in. (63.5 mm).
- Quick priming and immediate flow of product
- Handles fluid viscosities up to 5,000 cps and solids up to 0.09 inch (2.29 mm)
- Runs dry without damage. Provides air-tight seal for moisture-sensitive fluids
- Easy-out seal provides fast slide in and out of drums (through bung adapter) without disconnecting hoses. Easy-out seal accommodates slightly off-sized drums up to 2-1/2 in. (63.5 mm).
Excellent for abrasive, low-to-medium viscosity fluids and shear sensitive materials
- Easy Maintenance Low internal volume reduces waste and makes clean-up easy. Stainless steel bolts resist vorrosion and provide positive positioning for easy reassembly.
- Fluid Compatibility Housings available in aluminium, stainless steel, polypropylene, groundable acetal or Kynar.
- Fluid Control Choice A wide range of seat and ball options ensure fluid compatibility and positive seal for maximum efficiency, long life and better suction lift.
- Long-Lasting Rod Design 300 Series stainless steel rod designed for long life and corrosion resistance – even in wet air.
- Unique, Patented Air Valves Three-way Pilot Valve for non-sticking operation. All parts are replaceable without opening wet body parts. Aluminium parts are anodized or epoxy coated to resist corrosion usually caused by dirty air. No air-line lubrication is required.
- Precision-Fitted Parts Long-wearing end-bearings assure positive rod alignment and are easily replaced.
- Rugged Exterior Construction Construction resists corrosion, prevents leakage and ensures clean fluid changes. Anodizing on aluminium wetted parts and e-coat epoxy air section resists tough environments.
- Pump wetted parts and center section available in different materials The availability of multiple materials make it possible to use the pump in a wide range of applications: from low to high abrasive and corrosive fluids.
