PLACING INTO SERVICE
AIR AND LUBRICATION REQUIREMENTS
should be used on thread connection. Tighten all fittings. Use cau-
tion not to damage threads.

erate more efficiently and yield longer service life to moving parts and
mechanisms.
• Installanairlinefiltertoprovidegoodqualitycleananddryair.Install
it up stream from the regulator.
OPERATION
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.
• Inmostinstallations, lubricationisnotrequired. Ifthepumpneedsto
havelubrication,installanairlinelubricatorandsupplyitwithagood
grade of non-detergent oil or other lubricant compatible with Nitrile
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 pumpcycling slowlyby raisingthe pressureto 20 -30p.s.i.
(1.4 - 2.1 bar).
5. Close the dispensing device. Allow the pump to stall and build line
pressure. Check for anyleaks andtighten fittingsas needed. 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.
SHUTDOWN
• Disconnecttheairsupplyfromthepumpifitistobeinactiveforafew
hours. Open the dispensing device to relieve line pressure.
• Connectafluidhosetothepumpoutlet.Inmostcasesapipesealant
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.
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 - Allthreadsarerighthand.Refertofigure2.These

tion). Replacethe(19) “O” ringandassemble(14) pistonto(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 re-attach the (24) inner check.

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)lowercapand(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)spooltoremovethe(4)sleeve.Grabthenoseof(7)spooland
pull out. Repeat for other sleeve and spool.
TROUBLE SHOOTING
If the pump will not cycle or will not deliver material.
• Becertaintocheckfornon-pumpproblemsincludingkinked,restric-
tiveorpluggedinlet/outlethoseordispensingdevice.Depressurize
the pump system and clean out any obstructions in the inlet / outlet
material lines.
• Check all seals, including track gaskets.
• Check direction of “U” cup lips.
REASSEMBLY - Thoroughly clean and lubricate all seals and
bores with ShellGadus S2 U1000upon 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.
PUMP DISASSEMBLY DETAIL
A) Remove the four
nuts from the base
of the Air Motor.
B) Grasp the lower motor cap
and pull out the motor and
upper section of the lower
section.
C) Unlock the (24) inner
check from the piston
rod.
