Pro-Series Diaphragm Pumps Overview Program

Pro-Series Diaphragm Pumps Overview • Pro-Series Pumps – Complete Pump Line § Metallic / Non-Metallic Models – Feature Benefits § Pro-Series Value Proposition 2 Insert Footer

Pro-Series Pumps • A complete Diaphragm Pump line – 1” through 3” Metallic Models § Aluminum, Stainless and Cast Iron – 1” through 2” Non-Metallic Models § Polypropylene and PVDF • Capable of meeting the most demanding pump applications – When performance & reliability are critical – Features that provide excellent reliability § § Non-icing motor Non-stalling air valve Bolted Construction High Flow rate 3 Insert Footer

Stainless Steel Models • For Transfer of Aggressive Fluids – p. H of 0 -3 and 11 -14 • 666251 -X-C – 2” Ports NPT & BSP – 172 -gpm (651 -lpm) • 666301 -X-C – 3” Ports NPT & BSP – 237 -gpm (897 -lpm) • Investment cast wet ends provide: – Smooth clean internal/external surface finish 4 Insert Footer

Cast Iron Models • Provides Superior Abrasion Resistance – Excellent life in wastewater, sump and abrasive slurry applications § For fluids with p. H of 4 -5 and 9 -10 – 666252 -X-C § 2” Ports NPT & BSP § 172 -gpm (651 -lpm) – 666302 -X-C § 3” Ports NPT & BSP § 237 -gpm (897 -lpm) 5 Insert Footer

Feature-Benefits: Unbalanced Air Valve • Feature Description – Center section of valve is constantly pressurized § Automatically resets valve to prevent stalling • Benefit – Eliminates stalling associated with competitive brands utilizing a balanced valve – Ensures pump operates on demand 6 Insert Footer

Pro-Series Valve Operation • Step 1: – Valve is at rest – Air is supplied to the Right Diaphragm Chamber – Left Diaphragm Chamber exhausts to atmosphere 7 Insert Footer

Pro-Series Valve Operation • Step 2: – Pilot Rod shifts, sending signal to large end of Major Valve § Major Valve shifts – Right Diaphragm Chamber exhausts to atmosphere – Air supplied to Left Diaphragm Chamber 8 Insert Footer

Pro-Series Valve Operation • Step 3: – Pilot Rod shifts, signal to large end of Major Valve is eliminated § Major Valve resets – Air supplied to Right Diaphragm Chamber – Left Diaphragm Chamber exhausts to atmosphere 9 Insert Footer

Feature-Benefits: O-Ring Seal • Feature Description – Major valve rides on O-rings as it reciprocates in air motor • Benefit – Eliminates blow-by of compressed air at Air Valve § When fluid flow stops, the flow of compressed air also stops – O-Rings wipe away contaminants from air supply 10 Insert Footer

Feature-Benefits: No-Lube Operation • Feature Description – ARO Diaphragm Pumps DO NOT require air line lubricant – Use a Filter/Regulator on air inlet § Recommended F-R in each catalog • Benefit – One less maintenance step § Instruct customer not to use oils that harm the pump: ATF, Vaseline, Tool Oil, Valve Oil, Ethylene-Glycol, WD-40, etc. 11 Insert Footer Note: “No-Lube Operation” means no air-line lubricant is required.

Feature-Benefits: Bolted Construction • Feature Description – IR/ARO diaphragm pumps use eight bolts to secure fluid caps to the pump center body • Benefit – Avoids leakage associated with band-clamp fasteners § Band clamps stretch and fatigue – Provides uniform torque across seal point § Avoids leaks 12 Insert Footer

Feature-Benefits: Ease of Maintenance • Bolted Construction – Speeds repair process § Easier to re-assemble § Provides better alignment/ seal between components parts – Pre-assembled Service Kits § Include items to conduct normal repair § Simplify ordering process – O-Ring Seal § Air motor elastomers are wear items § Does not require replacement of full spool/valve-body assemblies 13 Insert Footer
