Industrial Gear Pumps For Reliable Fluid Management

Gear pumps are positive displacement technologies used for accurate industrial fluid handling. ARO solutions support flows up to 261 m³/h (1,150 GPM), pressures up to 31 bar (450 psi), and viscosities up to 4,400,000 cSt, depending on the product range.

With more than 95 years of expertise, ARO supports mission‑critical industrial processes worldwide.

These solutions are engineered for demanding industrial process applications. They combine robustness, precision, and durability for continuous operation. Alsp they are suitable for elevated pressure, high temperature, abrasive, and high-viscosity fluids.

Performance & Capabilities

• They provide accurate flow control with reduced liquid shear.
• They cover flow rates up to 261 m³/h (1,150 GPM), depending on configuration.
• They operate at pressures up to 21 bar (300 psi) for standard process applications.
• Selected designs reach 28 bar (406 psi) for severe duty conditions.
• They support operating temperatures up to 260°C (500°F).

Fluid Handling

• These solutions handle demanding viscosity levels and, for specific designs, fluids containing solids.
• They ensure reliable transfer without seizure risk.

Sealing & Materials

• Advanced sealing options are available, including TuffSeal™, single and double mechanical seals, and slurry seals.
• Materials include cast iron, stainless steel, AISI 4140, and 17-4 PH.

Applications & Benefits

• These solutions are widely used in chemical processing, asphalt handling, food production, polymers, and technical fluids.
• They are engineered to reduce downtime and extend component service life.

These solutions are designed for applications requiring leak‑free and seal‑less operation. They use magnetic coupling technology to eliminate dynamic seals and reduce maintenance.

Performance & Capabilities

• They cover flow rates from 2.3 to 2,460 L/h (0.6 to 650 GPH).
• They support nominal differential pressures up to 17.2 bar (250 psi).
• System pressure can reach 34.5 bar (500 psi), depending on configuration.
• They handle fluid viscosities from 0.3 to 2,000 cP without speed reduction.
• Operating temperatures range from -46°C to 176°C (-50°F to 350°F).

Precision & Applications

• These solutions deliver pulse-free flow with metering accuracy within ±1%.
• They are ideal for chemical processing, dosing, cooling, and sensitive fluid applications.
• ATEX-certified configurations are available for hazardous environments.
