AF0409A Series 2-Ball Piston Pump
Overview
Simply Versatile
2-ball pumps are among the most versatile in the ARO line. They are capable of handling applications from simple transfer to the extrusion of low- to medium- viscosity materials up to 100,000 centipoise (cPs) with fluid delivery up to 18.1 gpm (68.6 L/min).
Applications advantages of 2-balls:
Spray: 2-ball pumps deliver the constant flow rate and
pressure needed for consistent and efficient coatings
applications
Transfer & Supply: Depending on the
model, some 2-ball pumps can achieve flow rates up to 18.1 gpm,
providing dependable results
Extrusion: 2-ball pumps
generate pressure to handle extrusion of low-to
medium-viscosity
Lubrication: ARO 2-balls pumps
provide the flow and pressure required for moving light oils and
grease lubricants
High Pressure Cleaning: ARO Wash
Pump Packages are portable and offer the the right option for
industrial cleaning applications
Materials advantages of 2-balls:
- Sheer sensitive materials: ARO 2-ball pumps minimize friction points to prevent fluid shear, when compared to other similar pumping technologies
- Abrasive and high solid materials: ARO 2-ball pump minimize friction points and allow smooth passages to maintain fluid consistency
- Optional ceramic coating provides an even stronger defense against highly abrasive fluids like paint and glass-filled sealer
