River Pump Power Reduction 1

[itsmoked]

Have a river pump with a motor.

The motor is 440vAC, 60hz, 100hp, 134A , 3-phase. rated to output 2,045cubic/meter/min of water.

It's tripping its protection quickly and repeatedly.

It's also delivering 20% more water than expected, (2,454cubic/meter/min).

My take is that the twenty percent is pulling 20% more power hence the trips.
My advice is to restrict the outlet to reduce the mass-flow.

Now seeing the pictures finally, it shows the pump is an axial propeller type. Can I restrict the flow on this type and reduce the loading? Is a propeller a centrifugal pump?

I pretty much agree with all that LI. Some things we'll probably never have answered to our satisfaction.

Keith, many unknows to which we will never get answered, but doesn't matter now. It works, therefore 100% success.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
