Wilden Pump & Engineering Company is part of PSG Dover, a global manufacturer of pumps, systems, and related flow-control solutions for the safe, efficient, and reliable transfer of critical and valuable materials.
Wilden Pump & Engineering’s journey began in a walnut grove in San Bernardino County, CA, through the genius of Jim Wilden, after a large water pipe ruptured several feet below ground. Specifically, the AODD pump would be a solution for those needing a pump that could handle pumping water, slurry, and other finely divided substances.
Wilden is an established global distribution network, available in over 160 countries with more than 180 distributors worldwide. They promise to keep innovation and a customer-focused culture at the forefront of their operations.
Jim Wilden invented the air-operated double-diaphragm (AODD) pump in 1955. It was a revolutionary invention in the pump industry that continues to drive Wilden Pump & Engineering Company (a subsidiary of PSG, a Dover Company). Their advancements in pump engineering have significantly evolved throughout the past 65+ years.
Wilden is consistently pioneering new innovations while producing air-operated double-diaphragm pumps that always provide exceptional reliability, efficiency, performance and durability– making them a global leader in AODD pump design. As a result, many markets utilize Wilden AODD pumps, including:
- Water and Wastewater
- General Industrial
- Chemical Processing
- Oil and Gas
- Military and Marine
- Paints and Coatings
How AODD Pumps Work
Air-operated double-diaphragm pumps operate efficiently and safely by displacing the fluid from one chamber to another upon each “stroke.” They are driven by compressed air and given a specific amount of pressure per stroke to achieve the desired results. They are classified as reciprocating, positive-displacement pumps.
AODD pumps only have a few wetted parts and utilize a very simplistic yet ingenious design that provides precision pumping results while better protecting the fluids and materials going through the pump.
Here are Wilden’s primary product lines:
The Pro-Flo Series is Wilden’s workhorse AODD pump. It is commonly used in oil, gas, and chemical processing and utilizes a simplified air distribution system (ADS) for efficient performance. The simplistic design–using only thee moving parts–achieves more uptime and minimal maintenance or repairs because of their reliability and ease of use. Pro-Flo pumps are available in different diaphragm materials and configurations to suit specific fluid transfer applications:
- Bolted Metal
- Clamped Metal
- Bolted Plastic
- Clamped Plastic
Pro-Flo SHIFT Series
Upgrade to the Wilden Pro-Flo SHIFT Series for optimal energy efficiency. This pump offers the same pumping benefits and construction material options as the standard Pro-Flo Series with higher efficiency. In addition, the SHIFT Series eliminates overfilling, which can waste air with each stroke. The result is up to 60% in compressed air savings without any sacrifice in performance.
Wilden offers a wide variety of pumps in their Specialty Series. AODD pumps can handle specific fluids and processing applications in different industries:
- Saniflo Hygienic Pumps
- Saniflo FDA Pumps
- Accu-Flo Electronic Control Pumps
- Turbo-Flo Utility Pumps
- High-Pressure Pumps
- Stallion Mining Pumps
- Brahma Large Solids Handling Pumps
- GPS CSA-Certified Pumps
- UL Fuel Transfer Pumps
- Velocity Compact Pumps
The Wilden SafeGuard is the pump industry’s first Internet of Things (IOTT) smart device designed specifically for AODD pump systems. It provides real-time performance monitoring and alerts through 24/7 Cloud connectivity to keep your pump equipment running at optimal efficiency.
Wilden’s expert design in pump diaphragms offers various materials, including thermoplastic elastomers (TPE), polytetrafluoroethylene elastomers (PTFE), and rubber elastomers. They also provide a variety of unique diaphragm designs for specialized applications:
- Chem-Fuse IPD
- Pure-Fuse IPD
- EZ-Install Diaphragm
- Full-Stroke PTFE Diaphragm
- Reduced-Stroke PTFE Diaphragm
- Traditional AODD Diaphragm
- Ultra-Flex Diaphragm
Parts & Accessories
Wilden also manufacturers spare parts and accessories that enhance AODD pump performance. They have what you need to maintain and repair your Wilden pumps with minimal downtime.
