Re: PQ Measurements

Hi, thanks for a good post and lesson.

Is this pump replaced since it drops around 30 Lpm when at max pressure? A good thumbrule is to accept around 10% loss of flow at max pressure. That's of course that the rpm on the motor is maintained.
Do you have a opinion about this?

Best regards
Jim
