Pneumatic Diaphragm ARO Pump –Reliable, Efficient, and Versatile Fluid Handling Solution
A
Pneumatic Diaphragm ARO Pump is a highly efficient, air-operated double
diaphragm (AODD) pump designed to handle a wide range of fluids, including
viscous, abrasive, and corrosive liquids. Manufactured with precision and
engineered for reliability, ARO pumps deliver superior performance in
industries such as chemical processing, water treatment, mining,
pharmaceuticals, food and beverages, and more. With its robust construction and
simple design, this pump provides long-lasting, maintenance-free operation even
in the most demanding environments.
Working Principle
The
Pneumatic Diaphragm ARO Pump operates using compressed air as the power source.
It consists of two flexible diaphragms connected by a common shaft. As
compressed air alternately enters each air chamber, it pushes one diaphragm
outward, forcing liquid out of the pump, while the opposite diaphragm draws
fluid in on the suction side. This back-and-forth movement creates a continuous
flow without the need for mechanical seals or lubrication.
This
simple yet effective design ensures safe and reliable operation in applications
where electric pumps may pose a risk—especially in hazardous or explosive
environments (ATEX zones). The absence of electric motors and mechanical seals
makes ARO pumps an ideal choice for transferring sensitive or volatile liquids.
Key Features and Benefits
- Air-Operated Efficiency
The ARO pump runs entirely on compressed air, eliminating the need for electrical connections and reducing installation costs. It’s suitable for remote or hazardous areas where electricity is restricted. - Self-Priming Capability
The pump can self-prime from a dry start and lift fluids up to 20 feet vertically, making it suitable for applications where suction lift is required. - Handles a Wide Range of
Fluids
Designed to manage viscous, abrasive, and shear-sensitive liquids, the ARO diaphragm pump can handle everything from water and chemicals to slurries, paints, and oils. - Corrosion-Resistant
Construction
Available in various materials such as polypropylene, PVDF, aluminum, stainless steel, and cast iron, the pump can be customized to handle corrosive chemicals or abrasive slurries safely. - Leak-Free Operation
The pump’s design includes check valves and flexible diaphragms that ensure a leak-proof system, minimizing contamination and environmental hazards. - Low Maintenance Design
With no rotating parts, mechanical seals, or lubricants, the pump requires minimal maintenance and has a long service life. - Variable Flow and Pressure
Control
The flow rate can be easily adjusted by regulating air supply pressure, allowing precise control over liquid transfer rates without complex electronics. - Safe for Hazardous
Environments
The pneumatic operation ensures spark-free performance, ideal for use in explosive atmospheres or industries handling flammable fluids. - Dry-Running Capability
The ARO diaphragm pump can run dry without damage, preventing costly downtime and simplifying startup operations. - Energy Efficient and
Cost-Effective
Advanced ARO air valve technology minimizes air consumption and ensures smooth, reliable performance while reducing operating costs.
