3 AMC3/AMS3 OPERATING INSTRUCTIONS Thank you for selecting a SAINT-GOBAIN PERFORMANCE PLASTICS ASTI model AMC3 AstiPure pulsation damper, series 3 (or AMS3: slurry applications). I Presentation The SGPPL ASTI pneumatic pumps of PFD/PFS range use bellows and generate a pulsed flow rate. In an application including a filter, the variations produced by a bellows pump (although significantly less than the ones from a diaphragm pump) can cause damage to the filter membrane and force particles through the filter. To compensate for these variations, SGPPL ASTI has designed a range of pulsation dampers for the PFD/PFS pumps. Part numbers are as follows: AMC1 (AMS1) for a flow rate up to 2.5 GPM, or 10 liters/min (PFD1/PFS1 or PRD1/PRS1 pumps), AMC2 (AMS2) for a flow rate up to 5 GPM, or 20 liters/min (PFD2/PFS2 or PRD2/PRS2 pumps), AMC3 (AMS3) for a flow rate up to 12.5 GPM, or 50 liters/min (PFD3/PFS3 or PRD3/PRS3 pumps), AMC4 (AMS4) for a flow rate up to 25 GPM, or 100 liters/min (PFD4/PFS4 pump). The damper should be installed on the discharge side of the pump and connected to the same air supply as the pump. The damper absorbs between 65 and 80% of the pulsations regardless of the fluid pressure or flow rate. All wetted parts are made of TEFLON PFA HP and PTFE. Other parts are made of high-tech plastics such as PVDF, PEEK etc. There are no metal parts. II Shipment All pulsation dampers are assembled in our clean room, tested with DI water, and double sealed in plastic bags before they are shipped. These steps are taken to ensure the product you receive is of the highest quality and free of contaminates. Upon receipt of the parcel, please inspect your shipment. If there is any visible damage, immediately contact the carrier or your local distributor. An operating instruction manual has been included in each package. Please request another copy if it has not been included. III Installation The damper should be positioned vertically as shown in the pneumatic diagram (see drawing APD CAB ), except for slurry applications: position the damper horizontally to avoid that any slurry deposit damages the first spire of the bellow (see drawing APD S CAB ). Fasten the damper with the Ø M8 tapping located beneath the damper. The pneumatic supply should be the same as for the pump (see III.3.1 on PFD3/PFS3 Operating Instructions): Use a dry air or nitrogen supply, Supply pressure between 29 and 72.5 PSI, or 2 and 5 bar (58 PSI, or 4 bar for the best results), Supplying tube: ID maximum 1/4" (6 mm), Connection 1/4" gas. 2/9

4 AMC3/AMS3 OPERATING INSTRUCTIONS The damper must be placed on the delivery side of the pump (See pneumatic diagram). Minimize the tube length between the pump and the damper for optimal performance. The pulsation damper part number is made up as follows: 1 2 straight connectors 2 1 straight connector 1 elbow connector 3 2 elbow connectors AMC/S3 22 Connection is made with TEFLON tube Ø 7/8"x1" (22x25mm) and nuts (Flare Fitting system). Fitting and tube are connected only by heating and forming with a special forming tool, available as an accessory (P/N MF12228). The AMC3/AMS3 pulsation damper can be supplied with straight or elbow fittings on the inlet and outlet. The union elbow can be rotated through 360 degrees by loosening the nuts and turning the connector to the required position. Retighten by hand. Caution: if your damper is marked with W, you must systematically change the manifold seals (P/N 2581, Mark D) when you loosen the nuts. If your damper is marked W, and you wish to change the side of the inlet and/or outlet manifolds, you must absolutely change the PFA seals (washers, P/N 2581, Mark D) located deep in the groove at the same time. Proceed as follows: 1) Remove the washers (with an air spray gun), 2) Fit the new washers in their grooves (a set of exchange seals is supplied with the damper: P/N WWES KIT S3), 3) Install and tighten the manifolds with a strap wrench (while tightening, you may here a bang). Part number marked K (AMC3 322K or AMS3 322K) indicates that the pulsation damper is supplied with KALREZ manifold (P/N 2789K, Mark D) and body O.rings (P/N 2791K, Mark C). Part number marked W (AMC3 322W or AMS3 322W) indicates that the pulsation damper is supplied with PFA flat manifold seals (P/N 2581, Mark D), a PTFE flat body ring (P/N 2582, Mark C), and special manifolds (P/N 2572M and 2573M, Marks E and F). Part number marked G (AMC3 322G or AMS3 322G) indicates that the pulsation damper will be supplied with special manifolds with no seals (P/N 2804G or 2558G, Marks E and F) and a PTFE flat body ring (P/N 2582, Mark C). AMS3 dampers are equipped with rounded spires bellows (P/N 2779S, Mark B) in order to handle abrasive products (slurry). 3/9

5 IV Applications AMC3/AMS3 OPERATING INSTRUCTIONS Before using the pulsation damper with chemicals please check: The manifold nuts are tight, The body tie rod nuts are tight. Caution: Because of the material of these tie rods, tightening of couple must be controlled (we recommend 5 N.m - Maximum is 7 N.m), The air/nitrogen supply is dry, clean, and between 29 and 72.5 PSI (2 and 5 bar), The inlet and outlet fluid connections are correctly fitted and tight. Important: To prevent the damper from damage, it must be supplied with air when there is pressure in the fluid circuit. Thanks to its TEFLON design, the AMC/AMS pulsation damper can be used with most chemicals without the possibility of ionic contamination (even in the case of a bellow's rupture). The use of the damper can significantly reduce the rate of the particle contamination in your system. The normal operating temperatures for the damper are from 32 F (0 C) to F (100 C). When the fluid temperature is greater than 140 F (60 C), pressure should not exceed 43.5 PSI (3 bar), and it is advised to regularly retighten the manifold nuts. V Preventive maintenance Important: for W dampers, the PTFE body seal (P/N 2582, Mark C) and PFA manifold seals (P/N 2581, Mark D) must be changed each time you disassemble the damper. For G dampers, the PTFE body seal (P/N 2582) must be changed each time you disassemble the damper. Retighten manifold nuts simultaneously and progressively with a strap wrench in order to ensure a correct tightness. Follow the same preventive maintenance schedule for the AMC3/AMS3 as for the pump (See V.2 on PFD3/PFS3 Operating Instructions). When the pulsation damper is used continuously, strip and check every year and replace if necessary the following parts: Shaft composite rings P/N 2793F Central shaft P/N 2557 Important: these parts should always be replaced together. Check also the following parts at the same time, and change them if necessary: Bellow P/N 2779 (AMC) or 2779S (AMS) Bellow O.ring P/N 2792 Body O.ring P/N 2791S Manifold O.rings P/N 2789S If the pulsation damper is used intermittently, it is advised to replace all wearing parts every 18 months (shaft composite rings and central shaft) and to check other parts (especially the bellow and other O.rings). VI Dismantling and repair Attention: part numbers quoted in this manual are those used on a standard AMC/AMS pulse damper. Before ordering, please check the spare parts list, the section view of the damper and the part numbers table (see encl. documents). 4/9

Unscrew it from the central shaft (P/N 2557), 5) Fit the new bellow (gently hand tighten), 6) To re-assemble, follow the above instructions in the reverse order from 4) to 1). For AMC/S3 W and G dampers, you must replace the body ring (P/N 2582, Mark C) before re-assembling. Manifolds nuts must be progressively tightened with a strap wrench. All TEFLON PTFE and PFA parts are very soft. Please handle with care to avoid damage. Do not put them on their sealing surfaces. Caution: Nuts (P/N 2783) must be cross-tightened with a torque wrench (no more than 5 N.m, otherwise tie rods could break). VI.2 Replacing central shaft and shaft composite rings Follow the previous steps from 1) to 5). Then: 6) Remove central shaft (P/N 2557) and unscrew the stopper (P/N 2900), 7) Remove the 4 composite rings (P/N 2793F) with the pick P/N 1643 (supplied in the tools kit P/N KPFD3), 8) Clean the core (P/N 2556) by removing the dust from previous wear by O.rings, 9) Each shaft ring (P/N 2793F) is composed of three parts: an O.ring, a slit spacer and a sleeve (Figure 1). Insert 4 new shaft rings with tools from our tool kit (P/N KPFD3). Attention: You should first place the rings in inner grooves (indicated as B and C), and then in outer grooves (indicated as A and D), as explained here after F Slit spacer Sleeve O.ring Slit spacer O.ring Groove D Groove C Groove B Groove A Figure 1 5/9

7 AMC3/AMS3 OPERATING INSTRUCTIONS o Installing rings in inner grooves B and C Installing slit spacers First place a slit spacer in each inner groove B and C: Use pliers (not supplied in the tools case) to reduce the diameter of the slit spacer (Figure 2), and then place it in the groove (Figure 3). Figure 2 Figure 3 6/9

8 AMC3/AMS3 OPERATING INSTRUCTIONS Installing O.rings Then place an O.ring in each groove: Insert the shorter side of the O.ring positioning tool (P/N 2505) in the core (P/N 2556). Place the O.ring against the tool and insert it into the groove (Figure 4): Long Short B C Figure 4 Installing sleeves Now place a sleeve in each groove with the sleeve insertion tool (P/N 2690): Squeeze the sleeve into a "bean" shape as described in Figure 5, and insert it in the tool (P/N 2690) Step 3 Step 2 Step 1 Figure 5 7/9

9 AMC3/AMS3 OPERATING INSTRUCTIONS While holding the shorter side of the O.ring positioning tool (P/N 2505) against the core, place the sleeve insertion tool (P/N 2690) equipped with the sleeve on the other side and push on the push button to release the sleeve free (Figure 6) Long Short Push Figure 6 Use the pick (P/N 1643) to correctly position each sleeve in its groove. Be careful not to damage the sleeve (Figure 7) Figure 7 8/9

10 AMC3/AMS3 OPERATING INSTRUCTIONS o Installing the rings in outer grooves A and D Proceed the same way to install rings in grooves A and D, but following a different order: first place the O.rings in their grooves (Figure 4), then the slit spacers (Figures 2 and 3), and lastly insert the sleeves (Figures 5 and 6). Use the longer side of the O.ring positioning tool (P/N 2505) to position O.rings and sleeves. 10) Important: when re-assembling central shaft, lightly wipe it with silicon grease (Molykote 111), 11) To re-assemble, follow the above but in reverse order. VI.3 Replacing the bellow and body O.rings After removing the bellow (VI.1, Step 5), remove the bellow O.ring (P/N 2792) and the body O.ring (P/N 2791S, Mark C). Carefully replace the new ones without scratching the surface of bellow (P/N 2779 or 2779S, Mark B) and body (P/N 2771, Mark H). VI.4 Replacing the manifold O.rings Follow steps 1) and 2) from VI.1, and replace the manifold O.rings (P/N 2789S, Mark D). Take care, as these parts are fragile, especially end connection surfaces. If your damper is marked with W, replace the manifold seals (P/N 2581, Mark D) and tighten progressively with a strap wrench.
