6.

Install the throat packings into the outlet housing 
(46) one at a time in the following order, with the lips 
of the v-packings facing down:

The male gland (40*), two UHMWPE v-packings 
(41*), one leather v-packing (42*), one UHMWPE 
v-packing, one leather v-packing (42*), one UHM-
WPE v-packing, and the bearing (41). Loosely 
install the wet cup (45).

7.

Push the displacement rod (22) up into the outlet 
housing (46) until it protrudes from the wet cup (45). 
Continue reassembling the pump in the reverse 
order of disassembly. Tighten the wet cup just tight 
enough to prevent leakage.

1.

Reinstall the displacement pump on the motor as 
explained in your pump manual.

2.

Reconnect the ground wire to the motor.

The fluid piston and intake valves are factory-set for 
high-volume pumping of heavy, spray-viscosity fluids.

For lighter fluids or lower volume requirements, or to 
reduce surging at the stroke change-over, decrease the 
travel of the balls (3 and 4). Move the pins (2) to a lower 
set of holes. See Parts, page 8 and refer to disassembly 
procedure above.

For heavier fluids or to increase the flow, increase the 
travel of the balls (3 and 4). See Parts, page 8 and refer 
to disassembly procedure above.

Always replace the male gland (40) and the bearing 
(47) when the throat packings are replaced.

If the ball travel is too short for the fluid being 
pumped, the fluid flow will be restricted.
