PLACING INTO SERVICE
AIR AND LUBRICATION REQUIREMENTS
sealant should be used on thread connection. Tighten all fittings.
Use caution not to damage threads.
Filtered air will help extend the life of the pump, allowing the pump to
operate more efficiently and yield longer servicelifetomovingpartsand
mechanisms.
OPERATION
• Install an air line filter to provide good quality clean and dry air.
Install it up stream from the regulator.
START-UP
• 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 non-detergent oil or other lubricant compatible with
Buna -N seals and set at a rate not to exceed one drop per minute.
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 fittingsasneeded. Adjust
pressure as required for the application.
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
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
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 orientaĆ
tion). Replace the (19) ``O" ring and assemble(14)pistonto(20)pisĆ
ton rod and retain with (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 secĆ
tion. Press the sections together and align the air inlet and pump
outlet as required and replace the four (1) bolts and (27) nuts (tightĆ
en to 80 in. lbs (9 Nm).
PUMP DISASSEMBLY / REASSEMBL
Y
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. DisĆ
connect air supply and relieve all system pressure prior to servicĆ
ing. 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. Grasp the (11) cylinder and remove the (20,14) piston assembly.
3. Remove (15) lower cap and (3) track gasket. Remove (12) retaining
ring, then pull (14) piston off (20) piston rod.
4. 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.
TROUBLE SHOOTING
5. Remove (36) adapter, releasing (10) muffler housing.
If the pump will not cycle or will not deliver material.
• Be certain to check for non-pump problems including kinked, reĆ
strictive or plugged inlet/outlet hose or dispensing device. DepresĆ
surize the pump system and clean out any obstructions in the inlet /
outlet material lines.
REASSEMBLY - Thoroughly clean and lubricate all seals with
Shell Darina ``EP" 2. Replace all soft parts with new ones included
in the repair kit.
Note: Refer to the illustration (Fig 2) for ``U" cup lip seal direction.
1. Replace the seals on both the (7) spools and (4) sleeves.
• Check all seals, including track gaskets.
• Check direction of ``U" cup lips.
PUMP DISASSEMBLY DETAIL
A) Remove the four
nuts from the base of
the Air Motor.
C) Unlock the (24) inner
check from the piston rod.
B) Grasp the lower motor
cap and pull out the motor
and upper section of the
lower section.
