The Pro-Flo® SHIFT is the new standard for AODD pumps. The innovative, yet simple, Pro-Flo® SHIFT Air Distribution System (ADS) features an “air control spool” that automatically optimizes air consumption and eliminates the overfilling that can lead to overcharging of the air chamber, all while causing no corresponding reduction in flow rate. The Pro-Flo® SHIFT’s revolutionary ADS design meters the air flow, allowing for just enough air to keep the pumping process operational. The results are a reduction in air consumption and operational costs while maximum operational efficiency and...

Progressive Diaphragm Thermoplastic Elastomer (TPE) • Polyurethane: An excellent general purpose diaphragm for use in non-aggressive applications. This material exhibits exceptional flex life and durability. Wilden’s most economical diaphragm. Also available as part of Wilden’s EZ-Install flex-profile diaphragm line. • Wil-Flex™: Made of Santoprene™, this diaphragm is an excellent choice as a low cost alternative to PTFE in many acidic and caustic applications such as sodium hydroxide, sulfuric or hydrochloric acids. Wil-flex™ offers excellent abrasion resistance and durability, at a cost...

Rubber Elastomers • Neoprene: An excellent general purpose diaphragm for use in nonaggressive applications such as water-based slurries, well water or sea water. Exhibits excellent flex life and low cost. • Buna-N: Excellent for applications involving petroleum/oil-based fluids such as leaded gasolines, fuel oils, hydraulic oils, kerosene, turpentines and motor oils. • EPDM: Excellent for use in applications requiring extremely cold temperatures. It may also be used as a low cost alternative for pumping dilute acids or caustics. • Viton®: Excellent for use in applications requiring...
