Pro-Series Diaphragm Pumps Overview
• Pro-Series Pumps– Complete Pump Line
Metallic / Non-Metallic Models
– Feature Benefits Pro-Series Value Proposition
Insert Footer3
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
Insert Footer4
Stainless Steel Models
• For Transfer of Aggressive Fluids– pH 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)

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
Insert Footer7
Pro-Series Valve Operation
• Step 1:– Valve is at rest
– Air is supplied to the Right Diaphragm Chamber
– Left Diaphragm Chamber exhausts to atmosphere
Insert Footer8
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
Insert Footer9
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
Insert Footer10
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
Insert Footer11
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.
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
Insert Footer13
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
