Pump Calibration

With the pump installed under normal operating conditions, place the suction tubing in a graduated container.
Fill the container with the same chemical normally injected, and run the pump until all air is removed. (Prime the pump).
Refill the container if necessary, and with the foot valve in the solution, note the amount of chemical in the container.
Using a stopwatch or timer, run the pump for a measured amount of time (example: 1 minute). Note the amount of chemical pumped during that time.

Tip: The longer the testing time, the more accurate the measurement.

Example:

During your 1 minute calibration period, say your injector pumped 2.5 ounces.

2.5 ounces per minute (OZM)

calibrating chemical feed pumps

Your pump is calibrated to pump 1.17 GPH - or - 28.08 GPD

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.

Note: All diagrams are strictly for guideline purposes only. Always consult an expert before installing the metering pump on specialized systems. The metering pump should be serviced by qualified persons only.
