Piston Pump Applications, ARO Piston Pumps Do It All
Why ARO Piston Pumps?
ARO piston pumps are designed for a wide range of industrial fluid handling tasks. These applications typically fall into four main categories: Spray Coating, Measuring & Dispensing, Extrusion, and Transfer. Understanding the fundamentals of each will help you choose the right pump configuration for your operation.
Spray & Coating Applications
Use Case: Applying protective coatings, adhesives, resins, or paints by spray, roll, or dip.
Common Industries: Automotive, aerospace, wood finishing, marine, general manufacturing.
Typical ARO Pumps Used:
- 2-ball piston pumps – For light-to-medium viscosity materials like paint and varnish.
- 4-ball piston pumps – Ideal for higher flow rates when coating large surfaces.
ARO 4-Ball Pumps: Precision Dispensing for Coating, Packaging, and Assembly Lines
ARO’s 4-ball pumps can deliver up to 4.5 GPM and operate at high cycle rates, making them ideal for continuous coating lines. Their stainless-steel wetted components are corrosion-resistant, offering longevity even with harsh solvents or waterborne coatings.
Measuring & Dispensing Applications
Use Case: Controlled metering and dispensing of fluids for batch or automated operations.
Common Industries: Electronics, packaging and automotive assembly.
Typical ARO Pumps Used:
- 2-ball and 4-ball piston pumps – Provide accurate, repeatable flow for low- to medium-viscosity fluids.
ARO Piston Pumps for Extrusion: Precision Flow for Tough Materials in Automotive and Industrial Manufacturing
ARO piston pumps offer precise volumetric control and smooth delivery—essential for filling, bonding, or lubricating applications. For instance, the ARO 2-ball 12:1 pump delivers consistent output, reducing waste and improving quality in automated lines.
Extrusion Applications
Use Case: High-pressure delivery of viscous materials like sealants, mastics, greases, and heavy adhesives.
Common Industries: Construction, automotive, energy, aerospace, and industrial equipment manufacturing.
Typical ARO Pumps Used:
- Chop-check piston pumps – For ultra-thick materials that require clean extrusion.
- 2-ball pumps – For medium-viscosity pastes and sealants.
ARO Chop-Check Pumps: High-Pressure Solutions for Ultra-Viscous Fluids and Transfer Applications
ARO chop-check pumps handle materials up to 1,000,000 cPs and can generate pressures up to 6,000 PSI, especially when paired with ram systems and fluid regulators.
Transfer Applications
Use Case: Moving fluid from containers (drums, totes, tanks) to point-of-use stations or processes.
Common Industries: Food and beverage, personal care, chemical processing, and general industry.
Typical ARO Pumps Used:
- 2-ball and 4-ball pumps – Chosen based on flow rate requirements and viscosity of the fluid.
ARO Piston Pumps: High-Performance Fluid Handling with Precision, Power, and Reliability
ARO transfer pumps offer exceptional suction lift and can handle both clean and abrasive fluids. For instance, the ARO 4-ball 6” air motor pump delivers high volume flow rates with excellent reliability—up to 15 GPM, making it ideal for fast, efficient fluid movement.
Accessorize for Performance
Many applications benefit from pairing your piston pump with the right accessories:
- Rams and air plates for heavy materials
- Regulators for pressure control
- Heated hoses for temperature-sensitive fluids
- Electronic cycle counters for process monitoring
Whether you’re spraying light coatings, applying glue with precision, pumping thick sealants, or simply moving liquids from one place to another, ARO piston pumps give you the power and flexibility you need. These pumps use special valves to control flow direction and deliver the right amount of material every time.
ARO piston pumps are a great fit for jobs like car assembly, painting, chemical handling, and sealing work. Since each pump cycle moves the same amount of fluid, they keep a steady flow even if the liquid gets thicker or pressure changes.
Built with tough materials, strong seals, and easy-to-fix parts, ARO pumps are made to last and require less maintenance. Their smart design reduces waste, improves accuracy, and helps your team get more done with less effort. With the right setup, you can boost safety, cut costs, and reduce mess for a cleaner, more efficient workspace—no matter the task.
Where Piston Pumps Shine
Piston pumps are the go-to solution when you need power, precision, and reliability. From automotive shops to chemical plants, they handle tough jobs with ease—making them a smart choice for many industries.
