8.0 Measuring the Pump’s Output - Volumetric Test.
This volumetric test will take into account individual installation factors such as
line pressure, fluid viscosity, suction lift, etc. This test is the most accurate for
measuring the injector’s output in an individual installation.

1. Be sure the Injection Fitting and Footvalve /
Strainer are clean and working properly.
2. Fill a large graduated cylinder with the
solution to be injected.
3. With the pump installed under normal
operating conditions, place the suction
tubing with the Footvalve / Strainer installed
in the graduated cylinder.
4. Push 3/8” tubing onto the primming valve.
Place the other side of the 3/8” tubing in the
solution tank. Make sure the priming valve
is closed by turning the valve to the right.
5. Run the pump until all air is removed from
the suction line and the solution enters the
discharge tubing.
If the pump does not easily prime, loosen
the priming valve 1 - 2 turns counter clock
wise. Once the air is removed close the
primming valve.
6. Remove the suction tubing from the
graduated cylinder and refill the graduated
cylinder if necessary. Note the amount of
solution in the graduated cylinder.
7. Place suction tubing with the Footvalve / Strainer installed back into the
graduated cylinder.
8. Run the injector for a measured amount of time. A longer testing time will
produce more accurate results.
9. Remove the suction tubing from the graduated cylinder. Measure the amount
of chemical injected.

Note: All diagrams are strictly for guideline purposes only. Always consult an expert
before installing the pump into specialized systems. The pump should be serviced
by qualified persons only.
CAUTION: Always wear protective clothing, face shield, safety glasses and gloves
when working on or near your metering pump. Additional precautions should be
taken depending on the solution being pumped. Refer to MSDS precautions from
your solution supplier.
Once all the digits are programmed, press the DOWN arrow to then select
between SEC (seconds) and MIN (minutes).
Use the UP arrow to scroll through SEC and MIN.
Press the MODE button. The SEC or MIN icon will stop blinking and the Hz
icon will blink indicating the number of pulses is ready to be programmed.
4 Enter the number of pulses to trigger the batch. (1 to 1999 pulses)
Press the DOWN button to select the digit to program. The digit will blink
when selected. (Moves to the next digit to the right.)
Press the UP button to change the selected digit.
Repeat until all digits are programmed.
Press the MODE button. Programming is complete.
To exit the programming mode, press and hold the MODE button for more
than two seconds. The PROGRAM arrow will disappear.
