It is good practice to monitor the conditions and performance of the Single Phase Jet Monoblock. Diagnosis may be carried out by checking the following: Check the current drawn by the pump at the duty flow rate Compare with data recorded when the unit was initially installed Any increase in motor current at duty flow rate may indicate a overload condition, possibly due to impeller rubbing against the stationary pump casing Measure the insulation resistance of the winding to check the condition of the motor...
13. Do’s and don’ts Do’s Don’ts Use the Jet Unit with Foot valve provided with the Do not use piping smaller than what is mentioned on pump the nameplate Ensure leak proof joints on the suction side to prevent Provide sufficient space around the pumpset so as air entry and therefore loss of priming to ensure proper airflow required for cooling of the motor...
