Changing the TSL

Changing the TSL

Check the condition of the TSL and the level in the res­ervoir every week, minimum. TSL should be changed at
least every month.

Part No. 206995 Throat Seal Liquid (TSL) carries resi­due from the pump rod into the reservoir. Discoloration
of the TSL fluid is to be expected during normal opera­tion. After some time the TSL will thicken and darken,
and must be replaced. Thick, dirty TSL will not pump
through the lines and will harden in the pump wet-cup.

How long TSL lasts depends on which chemicals are
used, how much is used, what pressure, and condition
of the pump seal and rod.

To avoid the buildup of static charge, do not rub the
plastic bottle with a dry cloth while it is attached to the
pump. Remove the bottle to clean, if needed.

2. Remove and empty the reservoir bottle. Clean any
residue.

3. Clean screen (Z) of inlet check valve (48c

‡). If check

valves are not sealing and dirty TSL is getting into
the wet-cup, replace the check valves (48c, 48d).
See F

IG. 1.

A drop in the level of TSL in the reservoir indicates that
the throat packings are starting to wear. Add TSL to the
reservoir and keep the level above the Minimum fill line.
Monitor the usage and condition of the TSL. If pumped
material bypasses the throat packings and enters the
TSL reservoir, replace the packings.

To change the TSL:

1. Shut off the pump.

Lower Reassembly

Repair

1. See FIG. 4. Place the halves of the piston (10)
around the packing (11) and snap them together.

2. Apply high strength (red) Loctite

®

263 or 2760 to
entire length of the piston rod (17) threads. Sealant
must be allowed to cure for a minimum of 12 hours
before use. Screw the rod through the piston and
spacer (44) and into the piston nut (12). Torque the
nut to 95-100 ft-lb (129-135 N•m).

3. With the inlet housing (15) turned upside down,
install the balls (5) and the gaskets (7*).

COMPONENT RUPTURE HAZARD

The relief valve seat (6) must be installed at the fluid
inlet, as shown in F

IG. 4 and FIG. 5. The relief valve

reduces the risk of pump overpressurization. The seat
cannot relieve pressure if installed on the other side of
the inlet housing.

4. Install the relief valve inlet seat (6) in the left side of
the inlet housing (15), as viewed in F

IG. 4 and FIG.

5. (Text cast into the inlet housing identifies the cor­rect location for the relief valve seat.) The pin (P) on
the seat must point into the housing. The pin limits
the positioning of the seat, ensuring that the vent is
not blocked by part of the housing. See F

IG. 6.

5. Install the inlet seat without a relief valve (33) in the
right side of the inlet housing (15).

NOTE: The inlet seats (6 and 33) are not reversible; the
chamfered side must face the ball.

6. Place the inlet manifold (18) on the inlet housing
(15). Apply removable (blue) Loctite

®

243 to entire
length of the screw (9) threads. Install the lockwash­ers (8) and screws (9), and torque to 25-30 ft-lb
(34-40 N•m).

7. Place the inlet manifold (18) in a vise. Place one
o-ring (2*) in each side of the inlet housing (15),
where the tubes (3) sit. Place o-rings (2*) in the
grooves at each end of the tubes. Place a gasket (4)
in both the inlet and outlet housing (15 and 16).
Position the tubes and cylinder (1) in the inlet hous­ing.

NOTE: It may be necessary to use a rubber mallet to set
the fluid tubes (3) and cylinder (4) in place.

8. Lubricate the inside of the cylinder (4). Slide the pis­ton assembly into the cylinder. Rotate the piston as
shown in F

9. Lubricate the throat packings and glands. Install the
spring (43) and one male gland (19†) in the throat
cartridge (40), then five v-packings with the lips fac­ing down: one UHMWPE (20†), one leather (25†),
UHMWPE, leather, UHMWPE. Install the female
gland (26†). Install three v-packings with the lips
facing up: UHMWPE, leather, UHMWPE. Install the
other male gland (19†).

10. Lubricate the o-ring (42†) and install it on the
wet-cup (41). Install the wet-cup finger-tight.

11. Install the o-ring (35†) on the throat cartridge (40).
Apply lubricant to the throat cartridge threads then
screw the cartridge into the outlet housing (16)
loosely.

12. Install the outlet housing (16). It may not seat well
on the tubes and cylinder. Install the screws (13)
and lockwashers (14) from the inlet housing (15). As
you tighten the screws into the outlet housing (16),
they will draw the housings firmly onto the tubes and
cylinders. Tighten the screws uniformly and torque
to 25-30 ft-lb (34-40 N•m).

15. Place a ball (23), seat (24) and gasket (7*) in each
side of the outlet manifold (22). Install the outlet
manifold on the outlet housing (16).

16. Apply removable (blue) Loctite

®

243 to entire length
of the screw (9) threads. Install the lockwashers (8)
and screws (9), and torque to 25-30 ft-lb (34-40
N•m).

NOTE: The outlet seats (24) are reversible.

17. Reassemble the spring (45), TSL pump piston seal
(46), and o-rings (47).

18. Reassemble the manifold and bottle assembly (48),
cap (49), collar (50) and screws (51). Torque the cap
(49) to 25-30 ft-lb (34-40 N•m).

19. Reinstall the coupling nut and collars on the piston
rod (17).

20. Fill the cavity in the bottom of the motor shaft with
grease. Reconnect the lower to the motor as
described in your separate pump manual.

13. Torque the cartridge (40) to 95-100 ft-lb (129-135
N•m).

14. Torque the wet-cup (41) to 70-75 ft-lb (95-102 N•m).
