Operation
Start-up: Single or Multiple Pump Systems
1.
Close the air regulators and bleed-type master air
valves to all but one pump.
2.
Open the master air valve from the compressor.
3.
For the pump that is connected, trigger the
dispensing valve into a 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, release the trigger.
4.
If you have more than one pump, repeat this
procedure for each pump.
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.
5.
Set the air pressure to each pump at the lowest
pressure needed to get the desired results.
WARNING
The maximum working pressure of each pump in
your system may not be the same. To reduce the
risk of over-pressurizing any part of your system,
be sure you know the maximum working pressure
rating of each pump and its connected compo-
nents. Never exceed the maximum working pres-
sure of the lowest rated component connected to a
particular 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:
10:(1) ratio x 100 psi air =1000 psi fluid output
[10:(1) ratio x 7 bar air = 70 bar fluid output]
[10:(1) ratio x 0.7 MPa air = 7 MPa fluid output]
Limit the air to the pump so that no air line or fluid
line component or accessory is over-pressurized.
6.
If your pump accelerates quickly, or is running too
fast, 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.
Never allow the pump to run dry of the fluid being
pumped. A dry pump quickly accelerates to a high
speed, possibly damaging itself, and it may get
very hot.
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 Accessories, page 12.
7.
Read and follow the instructions supplied with
each component in your system.
8.
Whenever you shut off the system, always follow
the Pressure Relief Procedure.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
