SPEED LIMITATIONS BY VFD
SPEED LIMITATIONS BY VFD
(OP)
Hello,
What are the limits of speed increase of an existing pump (2900 rpm 50 hz),
can we increase the flow from 50 to 100 m3/hr?
regards,
roker

Also can pump operated faster? Not cavitate or (if centrifugal as flow seems to indicate) fail due to overspeed if operating faster.

Is this an estimate before you try it?
Do you have an opportunity to speed the pump up and measure the flow to see what happens?
