Applications for the RF Series
The RF pump line is designed for industries where downtime is costly and reliability is critical:
- Mining & Construction – Cleaning heavy machinery, excavators, and trucks in the harshest conditions.
- Shipyards & Marine Industry – Hull cleaning, barnacle removal, corrosion control, and offshore maintenance.
- Industrial Surface Prep – Rust, paint, and coating removal from bridges, steel structures, and infrastructure.
- Pipe & Tank Cleaning – Oil, gas, and wastewater facilities rely on high PSI for sanitation and flow restoration.
- Municipal & Government Use – Hydro-demolition, graffiti removal, and large-scale infrastructure cleaning.
- Manufacturing & Food Processing – USDA-compliant sanitation with hot water compatibility.
- Hydrostatic Testing – Provides the high-pressure water supply required for pipeline and vessel testing.
By offering both high volume and high PSI, the RF is one of the most versatile pumps in AR’s industrial lineup.
Maintenance & Service
Unlike disposable consumer pumps, the RF Series is fully serviceable and rebuildable. AR backs the series with dedicated parts and kits, ensuring operators get years of reliable use.
