Compound Gauge (Optional)
The pump should not be subjected to high suction line vacuums.
To check on this, install a compound gauge at pump inlet.
For ultimate performance and life, the vacuum should be limited
to 5 inches of mercury. High vacuum conditions may cause
premature product failure and void warranty.
Pulsation Dampener
This device absorbs the shock and smooths out the pump discharge
pulsations, providing smoother operation. For the
proper operation of many unloader valves, the pulsation dampener
should be installed on the discharge side downstream
from the unloader valve. However, for maximum system protection,
the pulsation dampener may be installed upstream
from the unloader valve, provided the unloader valve will function
properly. The dampener can be mounted vertically or
horizontally.
Pressure Regulator
Use a pressure regulator to limit incoming pressure to 20 psi
when equipped with a suction side injector. Volume, pressure
and horsepower figures in pump performance tables do not
apply when incoming pressure exceeds 40 psi.
Pressure Gauge/Dampener
Use gauge capable of reading double the pump working pressure.
Use a silicone-filled gauge or a gauge dampener to protect
the gauge needle against pressure surges and provide
easier reading.
Operation
Priming
If the liquid is below level of the pump, some means
should be provided in installation to prime pump, such
as a foot valve or check valve to hold prime. Keep suction
lift to minimum and avoid unnecessary bends in the
suction line. Before starting pump, make sure air bleeder
valve or spray gun is open, or unloader valve is
adjusted to its lowest pressure. After starting pump,
open and close gun several times if necessary to aid
priming the pump. If pump does not prime within a few
seconds, stop motor and inspect installation for suction
line leaks or obstructions. Make sure that strainer is not
clogged. Be sure that suction line is not obstructed,
kinked or blocked.
If the pump is to operate hours at a time, check frequently
for:
1. Adequate liquid supply. Pump must not run dry for
