Manufacturer of progressive cavity, twin screw, roto mining station, and AODD pumps. Heavy-duty construction is designed to pump tough—to—handle fluids. Retrofit spare parts and new wear compensation stator available. Used in all heavy industry sectors.
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
