concept of automation for centrifugal pump fitting

operation maintenance and monitoring basics - goulds pumps

process parameters are often not fully defined as pumps are being specifiedand because no one was ever it's also possible for a pump that is perfectly suited to its first installation to become oversized or likely to be seen first in the bearings and/or mechanical seals the two parts of a centrifugal pump that fail most

energy savings with adjustable frequency drives for centrifugal

the key idea here is that the energy created is kinetic energy the amount of energy given to the liquid corresponds to the velocity at the edge or vane tip of the 4 centrifugal pumps friction head hf is the head required to overcome the resistance to flow in the pipe and fittings it is dependent upon the size condition

how to operate centrifugal pumps in series or parallel

jan 22 for two different pumps the head will still be added together on the combined pump curve but the curve will most likely have a piecewise discontinuity meaning to curve with protusions as pictured in in the 2nd pump curve below for help on reading centrifugal pump curves check out our previous post
