PLACING INTO SERVICE
AIR AND LUBRICATION REQUIREMENTS
Filtered air will help extend the life of the pump, allowing the pump
to operate more efficiently and yield longer service life to moving
parts and mechanisms.
y
Install an air line filter to provide good quality clean and dry air.
Install it up stream from the regulator.
y
Use an air regulator on the air supply to control the pump cycle
rate. Install the regulator as close as possible to the pump.
y
In most installations, lubrication is not required. If the pump
needs to have lubrication, install an air line lubricator and sup-
ply it with a good grade of non-detergent oil or other lubricant
compatible with Nitrile seals and set at a rate not to exceed one
drop per minute.
INSTALLATION
y
Mount and secure the pump as required for the application.
y
Attach a ground wire from the pump ground screw to a suitable
ground.
y
Connect a fluid hose to the pump outlet. In most cases a pipe
sealant should be used on thread connection. Tighten all fit-
tings. Use caution not to damage threads.
OPERATION
START-UP
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
psig (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 need-
ed. Adjust pressure as required for the application.
SHUTDOWN
y
Disconnect the air supply from the pump if it is to be inactive
for a few hours. Open the dispensing device to relieve line pres-
sure.
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) retain-
ing ring and (48) washer, then pull (14) piston off (20) piston
rod.
5.
Remove (2) cap and (3) track gasket. Push on the large OD 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 and 54) 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
(54) 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
orientation). Replace the (19) “O” ring and assemble (14) piston
to (20) piston 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 re-attach the (24) inner check.
8.
Slide the pump assembly back into the (26) base / lower pump
section. Press the sections together and align the air inlet and
pump outlet as required and replace the four (1) bolts and (27)
nuts, tighten to 80 in. lbs (9 Nm).
TROUBLESHOOTING
If the pump will not cycle or will not deliver material.
y
Be certain to check for non-pump problems including kinked,
restrictive or plugged inlet / outlet hose or dispensing device.
Depressurize the pump system and clean out any obstructions
in the inlet / outlet material lines.
y
Check all seals, including track gaskets.
y
Check direction of “U” cup lips.
B) Grasp the lower motor
cap and pull out the motor
and upper section of the
lower section.
