Operation

Pressure Relief Procedure

1.

Shut off the hydraulic supply line valve (S) first, then 
the return line valve (R).

2.

Open the dispensing valve, if used.

3.

Open all fluid drain valves (U) in the system, having 
a waste container ready to catch drainage. Leave 
drain valve(s) open until you are ready to pump 
again.

Prime the Pump

1.

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

IG

. 3 on page 12.

NOTE: 

During operation the TSL level in the reservoir 

will fluctuate slightly at pump changeover.

2.

Close the flow control valve (T) by turning knob 
counterclockwise reducing pressure to zero. Close 
the supply line shutoff valve (S) and the return line 
shutoff valve (R). Also verify that all drain valves (U) 
are closed.

3.

Check that all fittings throughout system are tight-
ened securely.

4.

Start the hydraulic power supply.

5.

Open the return line shutoff valve (R), then the sup-
ply line shutoff valve (S). Slowly turn the flow control 
valve (T) clockwise, increasing pressure until pump 
starts.

6.

Cycle pump slowly until all air is pushed out and 
pump and hoses are fully primed.

7.

Verify that pump actuations are priming the pump 
wet-cup. If not, confirm that the TSL pump piston is 
being depressed at bottom changeover, and that 
reservoir check valves are not stuck closed.

8.

Close the fluid shutoff valve (D) downstream of the 
pump. The pump should stall against pressure.

NOTE:

 In a circulation system, the pump operates con-

tinuously until the power supply is shut off. In a 
direct-supply system, the pump starts when the dis-
pense valve is opened, and stops when the dispense 
valve is closed.

Stop the Pump at the Bottom of 
Its Stroke

Relieve the pressure when you stop the pump for any 
reason. Stop the pump on the downstroke, before the 
motor changes over.

Shutdown

Follow the 

Pressure Relief Procedure

, page 10.

Always flush the pump before the fluid dries on the dis-
placement rod. See 

Flushing

 on page 11.

NOTICE

When shutting down the hydraulic system, always 
shut off the hydraulic supply line shutoff valve (S) first, 
and then the return line shutoff valve (R) to prevent 
overpressurizing the motor or its seals. When starting 
the hydraulic system, open the return line shutoff 
valve first.

NOTICE

Failure to stop the pump at the bottom of its stroke 
allows fluid to dry on the piston rod, which can dam-
age the throat packings and the TSL pump piston seal 
when the pump is restarted.
