PLACING INTO SERVICE
AIR AND LUBRICATION REQUIREMENTS
Filtered air will help extend the life of the pump, allowing the pump to op- erate more efficiently and yield longer service life to moving parts and mechanisms.
•Install an air line filter to provide good quality clean and dry air. Install it up stream from the regulator.
•Use an air regulator on the air supply to control the pump cycle rate. Install the regulator as close as possible to the pump.
•In most installations, lubrication is not required. If the pump needs to have lubrication, install an air line lubricator and supply it with a good grade of
INSTALLATION
•Mount and secure the pump as required for the application.
•Attach a ground wire from the pump ground screw to a suitable ground.
•Connect a fluid hose to the pump outlet. In most cases a pipe sealant
should be used on thread connection. Tighten all fittings. Use cau- tion not to damage threads.
OPERATION
1.Turn the air regulator to “0” pressure setting.
2.Immerse the lower pump end into the material.
3.Open the dispensing device.
4.Start the pump cycling slowly by raising the pressure to 20 - 30 p.s.i. (1.4 - 2.1 bar).
5.Close the dispensing device. Allow the pump to stall and build line pressure. Check for any leaks and tighten fittings as needed. Adjust pressure as required for the application.
SHUTDOWN
•Disconnect the air supply from the pump if it is to be inactive for a few hours. Open the dispensing device to relieve line pressure.
SERVICE
PUMP DISASSEMBLY / REASSEMBLY
NOTICE: The unique design of this pump allows for quick basic pump service without total removal from the drum (refer to the views below).
DISASSEMBLY - All threads are right hand. Refer to figure 2. These procedures are for the installation of repair kit parts. Disconnect air supply and relieve all system pressure prior to servicing. Carefully remove the parts, inspect parts for damage, nicks or excessive wear and determine if any parts will need replacement.
Follow the three disassembly steps in the detail views below and place the pump on a clean bench.
1.Remove (1) bolts. Remove (18) packing, (17) bushing and (16) “O” ring.
2.Remove (36) adapter, releasing (10) muffler housing.
3.Grasp the (11) cylinder and remove the (20, 14) piston assembly.
4.Remove (15) lower cap and (3) track gasket. Remove (12) retaining ring and (48) washer, then pull (14) piston off (20) piston rod.
5.Remove (2) cap and (3) track gasket. Push on the large o.d. end of the (7) spool to remove the (4) sleeve. Grab the nose of (7) spool and pull out. Repeat for other sleeve and spool.
REASSEMBLY - Thoroughly clean and lubricate all seals and bores with Shell Gadus S2 U1000 upon assembly. Replace all soft parts with new ones included in the repair kit.
Note: Refer to the illustration (figure 2) for “U” cup lip seal direction. 1. Replace the seals on both the (7) spools and (4) sleeves.
2.Locate the valve chamber on the (11) cylinder where the 3/8’’ dia. hole is located and install one of the (4) sleeves. Insert the (7) spool from the opposite end. Next, install the remaining sleeve and spool.
3.Replace the (3) track gasket and install (2) cap.
4.Replace the (13) piston “U” cups (refer to figure 2 for proper orienta- tion). Replace the (19) “O” ring and assemble (14) piston to (20) pis- ton rod and retain with (48) washer and (12) retaining ring.
5.Install the (20, 14) piston assembly using great care to collapse the outer lip of the second “U” cup, allowing it to slip into the cylinder.
6.Replace the (3) track gasket and install the (15) cap. Install the (16) “O” ring onto the piston rod, replace (17) bushing and (18) packing.
7.Replace the (25) “O” ring and
8.Slide the pump assembly back into the (26) base / lower pump sec- tion. Press the sections together and align the air inlet and pump out- let as required and replace the four (1) bolts and (27) nuts (tighten to 80 in. lbs (9 Nm).
TROUBLE SHOOTING
If the pump will not cycle or will not deliver material.
•Be certain to check for
•Check all seals, including track gaskets.
•Check direction of “U” cup lips.
