Features

• Durable non-metallic materials: Robust construction with thick walled injection, molded fluid casings and cast iron or aluminum center sections to withstand tough industrial applications.
• Efficiency: Motor design delivers optimum air efficiency
• Reliability: ARO’s patented ‘Unbalanced’ air valve ensures no-stall operation
• Versatility: Multiple porting options for your application needs – Available in Flanged, Threaded, or 3 piece Manifold configurations
• Environmentally sound: Bolted construction for leak-free fluid handling
• Easy maintenance and repair: Easy access to ball checks and fluid caps for maintenance and repairs
• High flow rate: The pump has a maximum flow rate of 100 GPM (378.5 LPM), making it ideal for high-volume applications. This makes the pump suitable for use in a variety of industries, such as chemical processing, food and beverage processing, and water treatment.
• High operating pressure: The pump has a maximum operating pressure of 120 psi (8.3 bar), making it suitable for demanding applications. This makes the pump suitable for use in applications where there is a need to pump fluids under high pressure, such as in the automotive and aerospace industries.
