WILDEN Air Operated Double Diaphragm Pumps

Atlas Trading – Industrial Machinery and Spare Parts supplier

Introduction

WILDEN air operated double diaphragm (AODD) pumps are globally recognized as one of the most reliable and versatile solutions for industrial fluid handling. Designed to operate in demanding environments, WILDEN pumps deliver exceptional performance when handling aggressive chemicals, viscous fluids, abrasive slurries and sensitive products.

With decades of engineering expertise and continuous innovation, WILDEN has established itself as a benchmark in diaphragm pump technology, offering solutions that combine operational safety, durability and process efficiency.

Advanced AODD Technology for Industrial Fluid Handling

WILDEN pumps operate using compressed air, eliminating the need for electrical components and ensuring safe operation in hazardous or explosive environments. The air distribution system (ADS) guarantees efficient air usage and consistent pumping performance, reducing energy consumption while maintaining high flow rates.

The double diaphragm design enables smooth and controlled fluid transfer, minimizing shear and making these pumps suitable for delicate or shear-sensitive products. This technology also allows dry running without damage, a key advantage in many industrial processes.

Exceptional Versatility Across Applications

WILDEN AODD pumps are engineered to handle an extensive range of fluids, from low-viscosity liquids to highly viscous materials, including solids-laden and abrasive media. Their ability to self-prime and operate under varying suction conditions makes them ideal for complex industrial systems.

These pumps are widely used in sectors such as chemical processing, oil and gas, ceramics, water treatment, food and beverage, pharmaceuticals and general manufacturing. Their flexibility allows seamless integration into existing production lines and fluid management systems.

Robust Construction and Material Flexibility

WILDEN pumps are available in a wide range of materials to ensure compatibility with different fluids and operating conditions. Options include metal constructions such as aluminum, stainless steel and ductile iron, as well as plastic materials like polypropylene and PVDF for highly corrosive applications.

Elastomer selection is equally critical, with diaphragm and seal materials designed to withstand chemical attack, abrasion and temperature variations. This flexibility ensures optimal performance and long service life across diverse industrial environments.

High Performance and Operational Efficiency

WILDEN AODD pumps are designed to deliver consistent flow rates and reliable performance even under fluctuating operating conditions. Their ability to handle high solids content and maintain efficiency with viscous fluids makes them particularly suitable for challenging applications.

The pumps can operate against closed discharge without damage, providing additional safety and process control. Flow can be easily regulated by adjusting air pressure, offering precise control without complex electronic systems.

Safety and Reliability in Critical Environments

One of the key advantages of WILDEN pumps is their intrinsic safety. Since they are air-operated, they can be used in ATEX environments where electrical equipment would pose a risk.

Their leak-free bolted construction reduces the risk of fluid loss and environmental contamination, while the absence of mechanical seals minimizes maintenance requirements and potential failure points.

This makes WILDEN pumps a preferred choice for industries where safety and reliability are critical.

Easy Maintenance and Reduced Downtime

WILDEN pumps are designed for quick and straightforward maintenance. Their modular construction allows easy access to internal components, reducing downtime and simplifying service operations.

The reduced number of wear parts compared to traditional pump technologies contributes to lower maintenance costs and increased operational uptime.

Energy Efficiency and Cost Optimization

The advanced air distribution system used in WILDEN pumps optimizes compressed air consumption, reducing operating costs while maintaining high efficiency.

Their ability to operate without electrical components also reduces installation complexity and associated costs, making them an economically advantageous solution for many industrial applications.
