From : Mr.M. S. Nimbalkar.

This refers to your e-mail message dated 16/1/2008.

We are confirming as follows :-

At the sales stage, no sales person can decide the model of the VFD without detailing is done.  We have never discussed about the model of the VFD during the discussion.  It was our mistake that we overlooked the model of the VFD in the minutes of meeting.  This does not mean that we should accept the model which is technically not required for our screw pump and whose cost is Rs.26,000/- more than the required model.  

Since we are giving guarantee for the total setup, let us have the liberty to select the VFD model of the screw pump.  Your model of the VFD is required for torque variation which is not required in our screw pump.  So at the time of negotiation, we were not knowing whether this model is only for speed variation or torque variation.  Hence this discrepancy arose.    Please confirm.
