12. Materials of Construction Product Overview Polypropylene PVDF Nylon Conductive Nylon Aluminum Stainless Steel (316) Stainless Steel (Electropolished)

13. Thermoplastic Diaphragms and Elastomers Product Overview Geolast® - Nitrile based material that replaces traditional Nitrile, Urethane, and Neoprene diaphragms Santoprene® - EPDM based material with excellent resistance to acids and bases

14. Thermoplastic Diaphragms and Elastomers Product Overview Pumps built with PTFE have a Santoprene® back-up diaphragm which maximizes cycle life. Competitive pumps without the backup diaphragm have very low cycle life Viton® is also available as an optional elastomer for many pump sizes

15. Air-Valve Product Overview Dissimilar plastic components used throughout the air system create lubricity - no additional lubrication is needed. The pilot assembly exerts a constant stream of pressure on one end of the air valve spool, then shifts the pressure stream to the other end which prevents a stall or the dreaded ‘centered’ condition. Air Valve Spool Cross-Section of Air Valve

17. All Plastic Air System Product Overview Resistance to attack from corrosive atmospheres or diaphragm rupture Reduces overall weight of pump

18. Solids Handling Capability Product Overview MAX-PASS System Increase solids handling capability by 300% Increase suction lift by 25% Mount pump in any position Available in Nitrile, EPDM, and FDA Viton® Shown with valve in open position

19. Solids Control (3/8“ 1/2“ 1“) Product Overview Control the pump via a PC, PLC, relay or switch Control the pump from a separately supplied speed or batch controller with the solenoid controller pump Using an air line on/off solenoid valve mounted in the air line on a standard pump

20. Drum Kits Product Overview

21. Understanding the Pump Curve Product Overview Point 1 is the air inlet pressure Point 2 is the required flow rate Point 3 is the outlet pressure of fluid (the right axis converts psig to feet (meters)) Air consumption is designated by the red lines (the closest iteration to point 2 is approximately 6 SCFM)

22. Adjusting the Flow Rate Product Overview Use a pressure regulator to adjust the air pressure. Use an air control valve (ball or needle valve) to adjust the amount of air going into the pump. Using a ball or throttling valve on the liquid discharge side of the pump.

23. Viscosity Product Overview Position pump as close to or below the level of the fluid Use large suction lines - up to 3 times the size of the inlet 3. Start pump slowly using a valve on the air line

24. Chemical Compatibility Product Overview Always select ‘A’ rated material to fluid combinations Note all temperature limitations for any given material, these are referenced by the superscript 1 or 2 (or an exact temperature, such as 150). After finding ‘A’ rated combinations, there may be more than one possible pump model. Select the pump based on price, application (such as UV exposure) or conditions of usage.

25. Temperature Ranges Product Overview Metal pumps: Up to 212oF (100oC) Polypropylene: 32oF (0oC) to 150oF (65oC) PVDF: 10oF (-12oC) to 200oF (93oC) Geolast: 10oF (-12oC) to 180oF (82oC) Santoprene: 10oF (-12oC) to 212oF (100oC) PTFE: 40oF (4oC) to212oF to (100OC)

26. Accessories Product Overview Isolation Dampeners / suppressors Air flow control valves Air filter/regulators with gauge On/Off air solenoid valves Companion flanges

27. Installation Guidance Product Overview Use a lube-free, clean, dry, compressed air supply Mount pumps in an upright position Never restrict fluid suction lines Practice preventive maintenance and make sure that the fasteners are at the proper torque

28. Typical Applications Product Overview Coating Ultrasonic Cleaning Acid Recovery Pressure Washers Porcelain / Glaze Ink / Adhesive Transfer Paint Manufacturing Fertilizer Application Food Processing Rust Inhibitor Application Precious Metal Reclamation Transfer Applications Mining Oil and Gas Waste Water Wind Energy Marine Lubrication Car Wash Solvent Transfer Plating Industrial Laundry
