Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever 
you see this symbol.

1. Close the pump air regulator and bleed-type master 

air valve (required in the system).

2. Hold a metal part of the dispensing valve firmly to a 

grounded metal waste container and trigger the 
valve to relieve the fluid pressure.

Start Up

1. If there are multiple pumps on the air line, close the 

air regulators and bleed-type master air valves to all 
but one pump. If there is only one pump, close its air 
regulator and bleed-type master air valve.

2. Open the master air valve from the compressor.

3. Open the dispensing valve into the grounded metal 

waste container, making firm metal-to-metal contact 
between the container and valve. Open the 
bleed-type master air valve and open the pump air 
regulator slowly, just until the pump is running. 
When the pump is primed and all air has been 
pushed out of the lines, close the dispense valve.

4. If there is more than one pump, repeat this proce-

dure for each pump.

NOTE: 

When the pump is, and with sufficient air sup-

plied, the pump starts when the dispensing valve is 
opened and shuts off when closed.

5. Set the air pressure to each pump at the lowest 

pressure needed to get the desired results.

6. Never allow the pump to run dry of the material 

being pumped.

NOTE: 

A pump runaway valve (G) can be installed on 

the air line to automatically shut off the pump if it starts 
to run too fast.

7. Read and follow the instructions supplied with each 

components in the system.

8. To shut off the system always follow the Pressure 

Relief Procedure.

This equipment stays pressurized until pressure is 
manually relieved. To help prevent serious injury 
from pressurized fluid, such as skin injection, 
splashing fluid and moving parts, follow the Pressure 
Relief Procedure when you stop spraying and before 
cleaning, checking, or servicing the equipment.

NOTICE

The pump has a rated ratio of 50:1. However, it is 
capable of reaching stall pressures equal to 60 
times the air input pressure. Calculate the fluid 
output pressure using the air regulator reading. 
Multiply the air pressure shown on the regulator 
gauge by 60. For example:

140 psi air x 60 = 8400 psi fluid output
0.97 MPa air x 60 = 58.2 MPa fluid output
9.7 bar air x 60 = 582 bar fluid output

Regulate air to the pump so that no air line or fluid 
line component or accessory is over pressurized.

NOTICE

A dry pump will quickly accelerate to a high speed, 
possibly damaging itself. If your pump accelerates 
quickly, or is running too fast, stop it immediately and 
check the material supply. If the supply container is 
empty and air has been pumped into the lines, prime 
the pump and lines with material, or flush it and leave 
it filled with a compatible solvent. Be sure to eliminate 
all air from the material lines.
