PLACING INTO SERVICE  
AIR AND LUBRICATION REQUIREMENTS  
should be used on thread connection. Tighten all fittings. Use cau-  
tion not to damage threads.  
Filteredairwillhelpextendthelifeof thepump, allowingthepumptoop-  
erate more efficiently and yield longer service life to moving parts and  
mechanisms.

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.

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).

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.

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

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
