Pro-Flo® Series Air-Operated Double-Diaphragm (AODD) Pumps

Wilden Pro-Flo FAQ

• How does the Pro-Flo ADS compare to the Pro-Flo SHIFT ADS in AODD pump performance?

  The Pro-Flo Series air distribution system (ADS) combines elegant simplicity with robust and reliable performance that end users have come to depend on for more than 20 years. With its wide range of sizes and material offerings, end users count on the Pro-Flo Series to deliver the consistent performance promised for challenging applications.

  On the other hand, the Pro-Flo SHIFT ADS is the industry's premier air distribution system and an ideal solution to increase productivity, lower energy consumption, reduce air consumption and simplify maintenance. With design benefits unmatched by any other ADS on the market, the innovative yet simple Pro-Flo SHIFT ADS features an air-control spool that eliminates overfilling of the air chamber, automatically optimizing air consumption with no reduction in flow rate.

• What’s the difference between bolted and clamped AODD pump assemblies?

  Clamped and bolted air-operated double-diaphragm (AODD) pump assemblies differ in their design, specifically how the manifolds and center section are assembled. Clamped AODD pumps have a set of large and small clamp bands that are tightened to keep the manifolds, air chambers and liquid chambers together. Bolted AODD pumps have a series of bolts and washers that hold the manifolds, air chambers and liquid chambers together. Selecting between clamped and bolted configurations depends on your application. For example, clamped designs are better suited for sanitary and clean-in-place (CIP) applications.

• What are the advantages of clamped vs. bolted AODD pump designs?

  Clamped air-operated double-diaphragm (AODD) pump designs are easier to disassemble and are used in applications requiring ease of maintenance and quick disassembly for frequent cleaning. Bolted AODD pump designs offer superior product containment and are better suited for applications involving hazardous chemicals.

• Can Wilden Pro-Flo Series AODD Pumps be safely submerged in liquid?

  No. Pro-Flo Air-Operated Double-Diaphragm (AODD) Pumps are not designed to be submerged. This is because they lack a single-point design, unlike other submersible pumps. For submersible AODD pump applications, consider the Wilden Pro-Flo SHIFT Series or Stallion® Series with sealed exhaust options.
