ARO pumps feature stall resistant   design, modular air motor / fluid sections.   Air operated double diaphragm pumps utilize a pressure differential in   theairchamberstoalternatelycreatesuctionandpositivefluidpressure   in the fluid chambers, ball checks insure a positive flow of fluid.   Pump cycling will begin as air pressure is applied and it will continue to   pump and keep up with the demand. It will build and maintain line pres-   sure and will stop cycling once maximum line pressure is reached (dis-   pensing device closed) and will resume pumping as needed.   S Always flush the pump with a solvent compatible with the material   being pumped ifthe materialbeing pumpedissubjectto“settingup”   when not in use for a period of time.   S Disconnecttheairsupplyfromthepumpifitistobeinactiveforafew   hours.   PARTS AND SERVICE KITS   Refertothepartviewsanddescriptionsasprovidedonpage4through7   for parts identification and Service Kit information.   S Certain ARO “Smart Parts” are indicated which should be available   for fast repair and reduction of down time.   S Service kits are divided to service two separate diaphragm pump   functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SEC-   TION is divided further to match typical part MATERIAL OPTIONS.   AIR AND LUBE REQUIREMENTS   WARNING EXCESSIVE AIR PRESSURE. Can cause pump   damage, personal injury or property damage.   S Afiltercapableoffilteringoutparticleslargerthan50micronsshould   beusedontheairsupply. Thereisnolubricationrequiredotherthan   the “O” ring lubricant which is applied during assembly or repair.   S If lubricated air is present, make sure that it is compatible with the   Nitrile seals in the air motor section of the pump.   MAINTENANCE   S Provide a clean work surface to protect sensitive internal moving   partsfromcontaminationfromdirtandforeignmatter duringservice   disassembly and reassembly.   S Keep good records of service activity and include pump in preven-   tive maintenance program.   S Before disassembling, empty captured material in the outlet man-   ifold by turning the pump upside down to drain material from the   pump.   INSTALLATION   S Verify correct model / configuration prior to installation.   S Retorque all external fasteners per specifications prior to start up.   S Pumpsaretestedinwateratassembly. Flushpumpwithcompatible   fluid prior to installation.   FLUID SECTION DISASSEMBLY   S When the diaphragm pump is used in a forced-feed (flooded inlet)   situation, it is recommended that a “Check Valve” be installed at the   air inlet.   1. Remove (61) outlet manifold, (60) inlet manifold.   2. Remove (22) balls, (19 and 33) “O” rings (if applicable) and (21)   seats.   S Material supply tubing should be at least the same diameter as the   pump inlet manifold connection.   3. Remove (15) fluid caps.   S Material supply hose must be reinforced, non-collapsible type com-   patible with the material being pumped.   NOTE: Only PTFE diaphragm models use a primary diaphragm (7) and   a backup diaphragm (8). Refer to the auxiliary view in the Fluid Section   illustration.   S Piping must be adequately supported. Do not use the pump to sup-   port the piping.   4. Remove the (14) screw, (6) diaphragm washer, (7) or (7 / 8) dia-   phragms, and (5) backup washer.   NOTE: Do not scratch or mar the surface of (1) diaphragm rod.   S Use flexible connections (such as hose) at the suction and dis-   charge. These connections should not be rigid piped and must be   compatible with the material being pumped.   S Secure the diaphragm pump legs to a suitable surface (level and   flat) to insure against damage by vibration.   FLUID SECTION REASSEMBLY   S Pumpsthat needtobesubmersedmusthavebothwetandnon-wet   components compatible with the material being pumped.   S Submersed pumps must have exhaust pipe above liquid level. Ex-   haust hose must be conductive and grounded.   S Flooded suction inlet pressure must not exceed 10 p.s.i.g. (0.69   bar).   S Reassemble in reverse order. Refer to the torque requirements on   page 5.   S Clean and inspect all parts. Replace worn or damaged parts with   new parts as required.   S Lubricate (1) diaphragm rod and (144) “U” cup with LubriplateR   FML-2 grease (94276 grease packet is included in service kit).   S FormodelswithPTFEdiaphragms:Item(8)Santoprenediaphragm   is installed with the side marked “AIR SIDE” towards the pump cen-   ter body. Install the PTFE diaphragm (7) with the side marked   “FLUID SIDE” towards the (15) fluid cap.   S Re-check torque settings after pump has been re-started and run a   while.   S VitonR and HytrelR are trademarks of the DuPont Company,   S KynarR is a registered trademark of Penwalt Corp.   S LoctiteR is a registered trademark of Henkel Loctite Corporation   S S SantopreneR is a registered trademark of Monsanto Company, licensed to Advanced Elastomer Systems, L.P.,   S LubriplateR is a registered trademark of Lubriplate Division (Fiske Brothers)   S PW10A-X-X   Page 3 of 8   Download from Www.Somanuals.com.
