6. Set the air pressure to each pump at the lowest
pressure needed to get the desired results.
NOTE:
A pump runaway valve can be installed not he
air line to automatically shut off the pump if it starts to
run too slow.
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. If the 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.
7. Read and follow the instructions supplied with each
component in the system.
8. When shutting off the system, always follow the
Pressure Relief Procedure
on page 10.
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 components. Never
exceed the maximum working pressure of the lowest
rated components 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 down on the regulator gauge. For
example:
50:(1) ratio x 100 psi air = 50000 psi fluid output
50:(1) ratio x 0.7 MPa air = 35 MPa fluid output
50:(1) ratio x 7 bar air = 350 bar fluid output
Limit the air to the pump so that no air line or fluid line
component or accessory is over pressurized.
