Prime the Pump
1.
Verify all connections and fluid lines are tight.
NOTE:
The pneumatic pressure regulator (E) and speed
control valve (R) (needle valve) both affect the pump
cycle rate. After inlet pressure is set, the needle valve
can serve as a speed control.
2.
Adjust the pneumatic pressure regulator (E) to
desired pressure.
3.
Open the primary bleed-type master pneumatic
valve (D). Slowly turn the speed control valve (R)
counter-clockwise, increasing air/gas flow to the
pump.
4.
Keep the pump cycle rate less than 1 cycle every 3
seconds while priming the pump.
Calibrate Chemical Dosage
1.
Set the pump to an estimated setting of the flow
rate.
2.
Follow the instructions provided with your calibration
gauge.
3.
Adjust the cycle rate with the speed control valve
(R) and/or the pneumatic pressure regulator (E).
4.
Repeat the steps 2 and 3 to verify your changes.
Repeat as necessary until the desired flow rate is
achieved.
Baseline Chemical Dosage Settings
, starting on page 40, for max-
imum flows at any given pressure.
NOTICE
Pump runaway may occur if the speed control valve
(R) is opened too far for pressure settings, causing
damage to the packing sets (102 and 107).

NOTICE
Maximum cycle rate is 60 CPM (cycles per minute),
and the minimum cycle rate is 10 CPM. All values are
at 0 psi back pressure. Cycle rates over 60 may
cause excess wear and premature seal failure.
