1. If you are pumping heavy viscosity fluid and  
Pressure Relief Procedure  
erratic pump operation develops, disassemble  
the pump as explained on page 5. To increase  
the ball travel in the intake valve, move the pin (18)  
to the center or upper set of holes. To increase the  
ball travel in the piston valve, place the piston in a  
vise, loosen the upper cap (27) to relieve tension  
on the plunger rod (23), and turn the plunger rod  
counterclockwise two complete turns beyond its  
factory-set position, or enough to set the total ball  
travel to 0.306 in. (7.8 mm).  
WARNING  
PRESSURIZED EQUIPMENT HAZARD  
The system pressure must be manually relieved to  
prevent the system from starting or spraying acci-  
dentally. To reduce the risk of an injury from acci-  
dental spray from the gun, splashing fluid, or  
moving parts, follow the Pressure Relief Proce-  
dure whenever you:  
2. If you are pumping lighter viscosity fluid and  
surging develops, disassemble the pump as  
explained on page 5. To decrease the ball travel  
in the intake valve, place the pin (18) in the lowest  
set of holes. To decrease the ball travel in the  
piston valve, place the piston in a vise, loosen the  
upper cap (27) to relieve tension on the plunger  
rod (23), and turn the plunger rod clockwise two  
complete turns beyond its factory-set position, or  
enough to set the total ball travel to 0.102 in. (2.6  
mm).  
D are instructed to relieve the pressure,  
D stop spraying,  
D check or service any of the system equipment,  
D or install or clean the spray nozzle.  
1. Shut off the air or hydraulic power supply to the  
pump.  
2. Close the bleed-type master air valve (required in  
air-powered systems).  
27  
3. Hold a metal part of the gun firmly to the side of a  
grounded metal pail, and trigger the gun to relieve  
pressure.  
23  
4. Open the drain valve (required in your system),  
having a container ready to catch the drainage.  
5. Leave the drain valve open until you are ready to  
spray again.  
Ball Travel  
If you suspect that the spray nozzle or hose is com-  
pletely clogged, or that pressure has not been fully  
relieved after following the steps above, very slowly  
loosen the nozzle retaining ring or hose end coupling  
and relieve pressure gradually, then loosen completely.  
Now clear the nozzle or hose.

Piston and Intake Valve Adjustment  
Ball Travel  
See Fig. 1. The fluid piston and intake check valves  
are factory-set for pumping medium viscosity fluids.  
The ball stop pin (18) in the intake valve is in the  
lowest set of holes. The piston ball travel is set at  
0.204 in. (5.2 mm), measured from the end of the  
adjustable plunger rod (23) to the top of the ball (22).  
This distance represents four complete turns of the rod  
(23) from the top of the ball.

5. Clean all parts of the intake valve and inspect  
Before you start:  
carefully for wear or damage. Inspect the seat (C)  
of the retainer and seat assembly (16), but do not  
attempt to remove it. If the seat is worn or dam-  
aged, replace the entire retainer and seat assem-  
bly.  
1. Have all necessary repair parts on hand. Recom-  
mended spare parts are marked in the parts list  
with a check mark, for example (3n).  
2. Packing Repair Kits are available for some pumps.  
See the parts list for your pump to order the cor-  
rect kit. Use all the new parts in the kit for the best  
results. Kit parts are indicated in the parts list with  
an asterisk, for example (5*).  
6. Pull the pump cylinder (9) straight off the outlet  
housing (24), being careful not to tilt it until it is  
clear of the displacement rod (8) and piston as-  
sembly (B).  
3. Always replace the glands when replacing the  
packings, whether or not you use a repair kit.  
7. Inspect the polished inner surface of the cylinder  
(9) for scoring, wear or damage by running a finger  
over the surface or holding the part up to a light at  
an angle. Replace if necessary.  
4. Use a compatible solvent to clean parts. Inspect  
for wear or damage and replace parts as needed.  
8. Remove the three screws (19) and washers (20),  
and disassemble the piston. Be very careful when  
handling the ball (22) and seat (13) as they can be  
very easily damaged. Clean all parts and inspect  
carefully for wear or damage. See Fig. 4.  
5. Use light, waterproof grease wherever lubrication  
is recommended.  
Disassembly (See Fig. 2)  
9. Unscrew the packing nut/wet-cup (1) from the  
outlet housing (24). Pull the displacement rod (8)  
down out of the outlet housing. Remove and  
inspect the outlet housing gasket (7).  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 4.  
10. Push the throat packings and glands (A) out of the  
outlet housing (24). Clean the outlet housing and  
throat packings, and inspect for wear or damage.  
1. Flush the pump, if possible. Relieve the pressure.  
2. Disconnect the air and fluid lines. Remove the  
pump from its mounting and clamp it in a vise.  
Disconnect the displacement pump from the motor  
as explained in your separate pump manual.  
11. Inspect the polished outer surface of the displace-  
ment rod (8) for scoring, wear or damage by  
running a finger over the surface or holding the  
part up to a light at an angle. Replace if necessary.  
3. Loosen the packing nut/wet-cup (1). Unscrew and  
remove the four tie bolts (30) and lockwashers  
(31). Pull the intake valve housing (14) off the  
pump.  
12. Do not disassemble the displacement rod  
assembly unless necessary. Before disassem-  
bling, carefully measure how far the adjustable  
plunger rod (23) protrudes from the lower cap (10).  
This determines the amount of piston ball (22)  
travel. Screw the plunger rod (23) out of the dis-  
placement rod assembly, and inspect the o-rings  
(3) in place. Disassemble the upper and lower  
caps (27, 10) from the displacement rod (8).  
Inspect the o-rings (4) in place.  
4. Remove and inspect the intake valve gasket (17).  
Unscrew the retainer and seat assembly (16) from  
the intake valve housing (14). Remove the ball  
stop pin (18), noting which holes it is in. Remove  
the intake valve ball (15). Handle the ball carefully  
as it can be easily damaged.
