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 con-
tact 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 con-
tainer 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.
