Solution Providing Advantages - AODD Pumps
Air-Operated Double Diaphragm (AODD) pumps are designed to handle challenging pumping scenarios, including suspended solids, high viscosity fluids, and corrosive materials. They operate using air or natural gas, which balances diaphragm conditions and extends their lifespan. These pumps are energy-efficient, consuming no energy when deadheaded, and are ideal for intermittent on-demand use.

Solution Providing Capabilities
AODD pumps can manage abrasive and shear-sensitive materials, high viscosity fluids, and solids up to 3 inches. They are sealless, self-priming, and can run dry without damage. The pumps are portable, submersible, and fully groundable, with certifications such as CE, ATEX, CSA, UL, USDA, and FDA.

Primary Markets Served
AODD pumps serve various industries, including oil and gas, food processing, biotech, pharmaceuticals, automotive, chemical, construction, mining, paint, ceramics, and wastewater treatment.

Signature Design Platform
The design includes an Externally Serviceable Air Distribution System (ESADS) for reliability and maintenance ease, all bolted construction for better sealing, and bottom discharge porting for solids handling, ensuring process reliability and consistent restarts.

Signature Configurations
Configurations include Heavy Duty Ball, Heavy Duty Flap, Containment Duty Ball, and Standard Duty Ball pumps, each offering specific benefits like in-line serviceable air valve systems and options for metallic and non-metallic materials.

Best Practices - AODD Selection and Sizing
Selection involves reviewing fluid characteristics, installation, and duty requirements. Proper sizing is crucial for extending mean time between failures and reducing total cost of ownership. Performance curves assist in selecting the appropriate pump size and materials.

Recommended Process Control Components
Best practices include selecting suitable process control components and accessories, such as Tranquilizer® options and drum pumps, to optimize performance and efficiency.

OEM Solutions and After-Market Service
OEM solutions and after-market service parts are available to support the longevity and performance of AODD pumps.

AODD Principle of Operation
The operation principle involves air pressure acting on the diaphragm, providing a balanced condition that enhances efficiency and extends diaphragm life.

Materials Profile and Installation
Recommendations for materials and installation ensure optimal performance and compatibility with various fluids and environments.

Warranty and Performance Guarantees
Warren Rupp offers performance guarantees and warranties to ensure customer satisfaction and reliability of their pump solutions.

Specifications
The document provides detailed specifications for various pump models, including dimensions, connection styles, pipe sizes, displacement per stroke, maximum flow per minute, maximum solids handling, and maximum discharge pressure. The pumps are designed for different applications, such as handling abrasive slurries, suspended solids, and hazardous chemicals.

Procedures
Instructions are provided for converting plastic pumps to drum or pail applications using adaptor kits made of chemically-resistant materials.

Standards and Norms
The pumps comply with ATEX 100a standards for safety in explosive atmospheres and use materials like Sand Casted Aluminum, Cast Iron, Stainless Steel, and Alloy C.

Recommendations
For optimal performance, use pumps with tranquilizers to minimize vibration and enhance suction lift capability. Containment duty pumps are recommended for handling highly corrosive and hazardous fluids.

Performance Curves
Performance curves illustrate the relationship between air inlet pressure, capacity, and air consumption, aiding in selecting the appropriate pump model.

Accessories
Accessories include drum and pail kits, pump support legs, and lids with adjustment screws, enhancing pump versatility and functionality.

OEM Solutions
Warren Rupp offers custom-built products, including private labeling and special accessories, with flexible Kanban agreements and just-in-time scheduling.

Key Features
Heavy Duty Ball and Flap Valve Pumps are robust and handle a wide range of fluids. Containment Duty Pumps have spill chambers and leak detection features for safe operation with hazardous liquids.

Leak Detection Systems
Leak detection methods include visual, electronic, and mechanical systems, emphasizing the use of chemically compatible driver fluids for effective leak detection.

Performance Curves and Specifications
Performance curves for various pump models show capacity and head pressure at different air or gas inlet pressures. Special Duty Ball - Natural Gas Pumps are certified for operation with natural gas and comply with NACE Standard MR0175/ISO15156.

Submersible Pumps
The PortaPump® and SludgeMaster™ are submersible pumps designed for specific applications, with the PortaPump® being battery-powered and portable.

Pumper Parts®
Pumper Parts® offers aftermarket service parts for standard duty pump brands, ensuring quality and compatibility.

Principle of Operation
SANDPIPER® pumps operate using compressed air, nitrogen, or natural gas, with a detailed explanation of the operation process.

Installation Guidelines
Recommendations include installing a surge suppressor on the discharge side and using flexible connections to reduce stress on piping and pump connections.

Quality Assurance
All pumps undergo rigorous testing for fluid and air leakage, rhythmic cycling, and mechanical noise to ensure high performance and reliability.
