Question About Inspection A Pump

Contact the pump manufacturer. What means, "on service"?

Hello

thank you

on service means pump work and full of fluid

1)Install a Differential Pressure gauge between suction and discharge line. Head delivered of the pump is the Pressure difference between those points. You monitor it. Normal pump would maintain a constant DP (Head). If DP is lowering that means somethings wrong with your pump. (Check the impeller, motor, bearings)

2) Check temperature of motor & bearing of casing- monitor it at regular basis. Increase of temperature means poorly lubricated or shaft misalignment

Need more details . General inspection includes physical inspection, abnormal sound, vibration, controls etc. Ensure that the preventive maintenance is carried out as per the manufactures recommendation.

I suggest that you follow

1. the Pump manufacturers specifications

2. the OEM hand book for installation and servicing

3. check the RPM, intake & discharge pressure with the OEM pump curve

and if the pump is still under the OEM warrantee, then ask them for the EXACT specifications you need & if you are having problems then get them to honour their contact commitment to fix your problem (if you have one), if not covered by the OEM then still ask for the details, pump curves etc.. so you can compare you findings with that of the pump curve.

As for standards... that will depend on what type of pump you have, who made it and what standard they made the pump too! You can try API standards for pumps.. google it..

I guess you meant IN-SERVICE?

Pump manufacturer curves, flow meter and a current probe are your best bet. supposing that the pump is working normally.

simply you go to a mechanic give him his fare and say your problem thats it there ends the matter
