I am using a differential controller for giving control signal to variable pump for keeping a constant difference between the temperature of the cold side of heat exchanger i.e (dT=12) can anyone tell me if I am using the equation right pictures attached.

With little thermal mass in the system and no deadbands the operation you are seeing is to be expected. Why not use some of the built-in controller types with dead bands, there are quite a few options that could work.
