Assemble the Displacement
Pump

1. Lubricate the intake packings and install them in the

valve body (16), with the lips of the v-packings
facing up, in the following order (see F

. 11):

the female gland (25*)

one PTFE packing (24*)

one UHMWPE packing (26*)

one PTFE (24*)

one UHMWPE (26*)

the male gland (23*)

2. With the beveled side facing up, press the intake

valve seal (39*) into the recess of the intake valve
packing nut (15) until it snaps into place.

NOTE:

The nose of the seal should be flush with or

slightly recessed into the face of the packing nut.

3. Place the flats of the valve body (16) in a vise.

Screw the packing nut into the valve body handtight.
Set the intake housing assembly aside.

4. Lubricate the piston seal (13*) and install it on the

piston seat (14). Screw the piston guide (11) onto
the seat (14).

5. Place the guide in a vise as shown in F

. 9, page

17, and torque the seat to 75–88 N

•

m (55–65 ft-lb).

If the priming piston rod (18) was removed from
the piston (12)

a. Place the flats of the piston in a vise.

b. Use an adjustable wrench on the flats of the rod

to screw the rod into the piston. Torque the rod
to 125–137 N

•

m (92–101 ft-lb).

NOTE:

Be careful not to create burrs on the flats of the

rod.

7. Place the piston seat/guide assembly onto the

piston (12) so the 45° beveled seating surfaces
match.

8. Screw the displacement rod (1) into the piston (12)

hand tight.

9. Torque the displacement rod (1) to 339–359 N•m

(250–265 ft-lb).

10. If the cylinder (10) was removed from the outlet

housing (9):

a. Lubricate the seal (8*) and place it on the top of

the cylinder.

NOTE:

The cylinder is symmetrical, so either end can

be the top.

b. Screw the cylinder into the outlet housing. See

. 13, page 20.

11. Lubricate the seal (42*) and install it in the groove

on the bottom of the packing housing (3).

12. Screw the packing housing (3) into the outlet

housing (9). Torque the packing housing to

203–
237

•

(150–175

ft-lb). See the Detail in F

. 13,

page 20.
