Page 2 of 8 66610X-X-C GENERAL DESCRIPTION MAINTENANCE The ARO diaphragm pump offers high volume delivery even at low air pressure and a broad range of material compatibility options available. Refer to the model and option chart. ARO pumps feature stall resistant design, modular air motor / fluid sections. Air operated double diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction and positive fluid pressure 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 pressure and will stop cycling once maximum line pressure is reached (dispensing device closed) and will resume pumping as needed. Refer to the part views and descriptions as provided on pages 4 through 7 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 SECTION is divided further to match typical part MATERIAL OPTIONS. S Provide a clean work surface to protect sensitive internal moving parts from contamination from dirt and foreign matter during service disassembly and reassembly. S Keep good records of service activity and include pump in preventive maintenance program. S Before disassembling, empty captured material in the outlet manifold by turning the pump upside down to drain material from the pump. AIR AND LUBE REQUIREMENTS S S WARNING EXCESSIVE AIR PRESSURE. Can cause pump damage, personal injury or property damage. A filter capable of filtering out particles larger than 50 microns should be used on the air supply. There is no lubrication required other than the O" ring lubricant which is applied during assembly or repair. If lubricated air is present, make sure that it is compatible with the O" rings and seals in the air motor section of the pump. OPERATING INSTRUCTIONS S Always flush the pump with a solvent compatible with the material S S S S being pumped if the material being pumped is subject to setting up" when not in use for a period of time. Disconnect the air supply from the pump if it is to be inactive for a few hours. The outlet material volume is governed not only by the air supply but also by the material supply available at the inlet. The material supply tubing should not be too small or restrictive. Be sure not to use hose which might collapse. 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. Secure the diaphragm pump legs to a suitable surface to insure against damage by vibration. FLUID SECTION DISASSEMBLY 1. Remove top manifold(s). 2. Remove (22) balls, (19) O" rings and (21) seats. 3. Remove (15) fluid caps. NOTE: Only Teflon diaphragm models use a primary diaphragm (7) and a backup diaphragm (8). Refer to the auxiliary view in the Fluid Section illustration. 4. Remove the (14) screws, (6) washers, (7) or (7 / 8) diaphragms and (5) washers. 5. Remove (3) O" rings. NOTE: Do not scratch or mar the surface of (1) diaphragm rod. FLUID SECTION REASSEMBLY S Reassemble in reverse order. S Clean and inspect all parts. Replace worn or damaged parts with new parts as required. S Lubricate (1) diaphragm rod and (2) O" ring with Key-LubeR grease. S Use ARO pn / 98930-T bullet (installation tool) to aid in installation of (2) O" ring on (1) diaphragm rod. S Be certain (7) or (7 / 8) diaphragm(s) align properly with (15) fluid S S caps before making final torque adjustments on bolt and nuts to avoid twisting the diaphragm. For models with Teflon diaphragms: Item (8) Santoprene diaphragm is installed with the side marked AIR SIDE" towards the pump center body. Install the Teflon diaphragm with the side marked FLUID SIDE" towards the fluid cap. Re-check torque settings after pump has been re-started and run a while.

(qty 2) retaining rings and Y325-24 O" rings (qty 2) are included in the service kit for the repair of larger pumps. MATERIAL CODE Service is divided into two parts − 1. Pilot Valve, 2. Major Valve. GENERAL REASSEMBLY NOTES: S Air Motor Section Service is continued from Fluid Section repair. S Inspect and replace old parts with new parts as necessary. Look for 637175 [A] = [B] = [Bz] = [C] = Aluminum Nitrile Bronze Carbon Steel [CI] = Cast Iron [D] = Acetal [Ny] = Nylon [U] = Polyurethane [SS] = Stainless Steel [Z] = Zinc deep scratches on metallic surfaces, and nicks or cuts in O" rings. S Take precautions to prevent cutting O" rings upon installation. S Lubricate O" rings with Key-Lube grease. S Do not over-tighten fasteners, refer to torque specification block on S view. Re-torque fasteners following restart. PILOT VALVE DISASSEMBLY 1. Remove (104) retaining ring. 2. Remove (123) screws and (122) O" rings. 3. Remove (118) piston rod, (121) sleeve bushing, (119) O" rings and (120) spacers from the (101) motor body. 4. Remove (103) sleeve and (102) O" rings. PILOT VALVE REASSEMBLY 1. Replace two (102) O" rings, if worn or damaged, and reinstall (103) sleeve. 2. Install one of the (121) sleeve bushings, (119) O" rings, (120) spacers and the remaining (121) bushing. 3. Carefully push (118) pilot rod into bushings etc. and retain on each end with the two (122) O" rings, retain with (123) screws. 4. Replace (104) retaining rings. MAJOR VALVE DISASSEMBLY 1. Remove (107) plate (or leg depending on model), (108 and 117) gaskets. 2. On the side opposite the air inlet, push on the inner diameter (111) spool. This will force the (109) piston out. Continue pushing the (111) spool and remove. Check for scratches and gouges. 3. Reach into the air section (exhaust side) and remove (116) spacer, (115) spacers, (113) O" rings, (114) O" rings, (112) washers, etc. Check for damaged O" rings. MAJOR VALVE REASSEMBLY 1. Replace (112) washer, (114) O" ring and (113) O" ring onto (115) spacer and insert etc. NOTE: Be careful to orient spacer legs away from blocking internal ports. 2. Lubricate and carefully insert (111) spool. 3. Install (117) gasket and (107). 4. Lubricate and install (110) packing cup and insert (109) piston into (air inlet side) cavity, the (110) packing cup lips should point outward. 5. Install (108) gasket and replace (107). V Smart Parts", keep these items on hand in addition to the service kits for fast repair and reduction of down time.

Low output volume, erratic flow, or no flow. S Check air supply. S Check for plugged outlet hose. S Check for kinked (restrictive) outlet material hose. S Check for kinked (restrictive) or collapsed inlet material hose. S Check for pump cavitation − suction pipe should be sized at least as large as the inlet thread diameter of the pump for proper flow if high viscosity fluids are being pumped. Suction hose must be a non-collapsing type, capable of pulling a high vacuum. S Check all joints on the inlet manifolds and suction connections. These must be air tight. S Inspect the pump for solid objects lodged in the diaphragm chamber or the seat area. Air bubbles in product discharge. S Check connections of suction plumbing. S Check O" rings between intake manifold and fluid caps. S Check tightness of (14) diaphragm screw.
