Changing the TSL

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

Part No. 206995 Throat Seal Liquid (TSL) carries resi-
due from the pump rod into the reservoir. Discoloration 
of the TSL fluid is to be expected during normal opera-
tion. 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. 

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.

2.

Remove and empty the reservoir bottle. Clean any 
residue.

3.

Clean screen (Z) of inlet check valve (VI). If check 
valves are not sealing and dirty TSL is getting into 
the wet-cup, replace the check valves (VI, VO). See 
F

IG

. 3.

4.

Fill the reservoir to the Maximum fill line with Throat 
Seal Liquid (TSL).

5.

Run pump. Each time pump rod reaches bottom of 
stroke, check that some TSL is pumped from reser-
voir through wet-cup and back to reservoir.

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.
