Operation
Startup
The maximum working pressure of each pump in
your system may not be the same. To reduce the
risk of overpressurizing any part of your system, be
sure you know the maximum working pressure rat-
ing of each pump and its connected components.
Never exceed the maximum working pressure of
the lowest rated component connected to a particu-
lar pump.
To determine the fluid output pressure using the air
regulator reading, multiply the ratio of the pump by
the air pressure shown on the regulator gauge. For
example:
5:(1) ratio x 100 psi air = 500 psi fluid output
[5:(1) ratio x 0.7 MPa ( 7 bar) air =
3.5 MPa (35 bar) fluid output]
Limit the air to the pump so that no air line or fluid
line component or accessory is over-pressurized.
WARNING
1. Open the master air valve from the compressor.
2. Trigger the dispensing valve into a grounded metal
waste container, making firm metal-to-metal
contact between the container and valve.
3. 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, release the trigger.
NOTE: When the pump is primed, and with sufficient
air supplied, the pump starts when the dispensing
valve is opened and shuts off when it is closed.
4. Set the air pressure to each pump at the lowest
pressure needed to get the desired results. Use
the regulator to adjust pump speed and pressure.
Never allow the pump to run dry of the fluid
being pumped. A dry pump quickly accelerates
to a high speed and could possibly damage
itself. If the pump accelerates quickly, stop it
immediately, and check the fluid supply. If the
supply container is empty and air has been
pumped into the lines, prime the pump and lines
with fluid, or flush it and leave it filled with a
compatible solvent. Be sure to eliminate all air
from the fluid system.
CAUTION
NOTE: A pump runaway valve can be installed on the
air line to automatically shut off the pump if it starts to
run too fast. See Air and Fluid Line Accessories on
page 6.
5. Read and follow the instructions supplied with
each component in your system.
6. To shut off the system, always relieve the
pressure.
INJECTION HAZARD
To reduce the risk of serious injury
whenever you are instructed to relieve
pressure, always follow the Pressure
Relief Procedure at left.
