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

14. Thermoplastic Diaphragms and Elastomers 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 Product Overview

15. Air-Valve 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. Cross-Section of Air Valve Air Valve Spool Product Overview

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

18. Solids Handling Capability 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 MAX-PASS System Product Overview

19. Solids Control (3/8 1/2 1) 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 Product Overview

20. Drum Kits Product Overview

21. Understanding the Pump Curve 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) Product Overview

22. Adjusting the Flow Rate 1.Use a pressure regulator to adjust the air pressure. 2.Use an air control valve (ball or needle valve) to adjust the amount of air going into the pump. 3.Using a ball or throttling valve on the liquid discharge side of the pump. Product Overview

23. Viscosity 1.Position pump as close to or below the level of the fluid 2.Use large suction lines - up to 3 times the size of the inlet 3. Start pump slowly using a valve on the air line Product Overview

24. Chemical Compatibility 1.Always select A rated material to fluid combinations 2.Note all temperature limitations for any given material, these are referenced by the superscript 1 or 2 (or an exact temperature, such as 150). 3.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. Product Overview

25.
