Capacity Calibration
After the first 12 hours of operation, the pump may be tested and calibrated to find the exact pump
capacity under specific operating conditions.
Usually, calibrating the pump at only 100, 50, and 10 percent capacity settings is enough to indicate pump
performance throughout the adjustment range.
The pump can be calibrated by measuring the decrease in liquid level pumped from a calibrated vessel.
This method is recommended for hazardous liquids because it eliminates operator contact with the liquid.
Milton Roy test-tube Calibration Columns are available for convenient and accurate calibration of any pump.
The pump can also be calibrated by collecting and measuring pumped liquid at the pump discharge port. It
may be necessary to create discharge head at the liquid take off point so that the pump will operate properly.
(See Section 2 for recommended ways to do this.).
CAUTION:
This method is not generally recommended as it may expose operating personnel to hazardous liquids.
Furthermore, the pump may over pump dramatically and the position of the capacity adjustment knob
may have little effect on measuring flow rate.
