Wilden® Brahma™ Flap Valve Bolted Metal AODD Pumps-- Maximum Solids Passage and Rugged Durability

The revolutionary Wilden® Advanced™ Series Brahma™ Flap Valve model bolted metal Air-Operated Double-Diaphragm (AODD) Pumps were specifically designed for maximum solids passage and high performance in the toughest applications. The Brahma pump has a unique top inlet and bottom discharge orientation and uses flap valves to allow the passage of large-size solids. These flap valves help the Brahma avoid damage from product entrapment and settling of solids in intermittent-duty applications. It features bolted construction and the ability to pass certain solids up to 51 mm (2″). It’s easy to maintain, externally serviceable and completely submersible, allowing the Brahma to be used in harsh environments, such as mine de-watering.

A variety of elastomer options, including Teflon® PTFE, are available to meet abrasion, temperature and chemical-compatibility concerns. The Brahma Advanced Series metal pumps are offered in die-cast aluminum and ductile iron. A variety of options, such as ANSI and DIN flanges, NPT/BSPT threads and specialized air distribution systems (ADS), are available to meet your specific application requirements.
