Without knowing how resilient the supply is to this motor, it would be extremely difficult. Is this in star-delta territory, VFVD or what? What vital interlocks does the process require of it?

Without any further details, I would suggest the following, least cost to most cost:

i) Direct On Line Starter

ii) Star-Delta Starter

iii) Soft Starter

iv) VFD

As for protection:

i) Thermal Overload Relay

ii) Low Cost Motor Protection Relay

iii) Comprehensive Motor Protection Relay

Don't be ridiculous. These are the services performed by a professional electrical engineer, not something that you ask to have done for free by anonymous people who have nothing to lose from making an error because they are 3000 miles away and making judgements based on 3 sentences.

"Can any one send main and control circuit for the above criteria.. please advice,"

Here's some advice. Hire a competent engineer.

This really is a question you should be asking (and paying) an engineer or consultant, not an engineering forum.

We are not a free consultancy and won't offer detailed advice that could get someone killed if it is misused or misinterpreted (even if we had all the required information to answer questions like this, which we never do).

Do this, if you're too cheap to hire an engineer, make the purchase contingent on the pump seller installing it.

It's called a "turn-key" installation. Not a "tur-key".

First choose the starter,then OL,CB,cable etc by going through earlier threads.Interlocks and controls should match site requirements.

Condensate return pump means steam. 132 kW to pump condensate means a LOT of steam. DCS system and control room means a LOT of steam in a very expensive plant. Doing this without the services of a QUALIFIED electrical engineer runs the risk of hugely expensive down time. Then in a large boiler with a non-functioning condensate return pump, the condensate may back up into pressure relief valves creating the remote possibility of a boiler explosion and killing someone. I think it best that we not facilitate this madness.
