Calibration pot
DKM provides many accessories around the pump : pulsation dampeners, double diaphragm shock absorber, check valves, diaphragm leakage detector, remote control actuators and frequency inverters.
A dosing pump is generally used alone, without an associated flow meter.
The user must rely totally on the value displayed on the stroke-adjustment system, because the pump is, by definition, of the Volumetric type.
The factory-established calibration curve may not reflect exactly the flow rate values obtained in-situ , in view of the nature of the liquid being pumped and/or the intake and viscosity conditions.
In this case, the calibration pot enables calibrating the pump performances.
The calibration pot is installed on a tapoff of the intake line, downstream from a line valve, with an isolation valve at its foot and a vent valve at its summit.
The calibration pot can be made of graduated PVC or glass, shielded against shock, for small flow rates and low intake pressures, or
It can be made of steel, with an external level indicator, for large flow rates and high intake pressures.
