Submersible Pumps

Why insulating the pump's motor with resin?

The need to move towards more environmentally respectful products is pushing submersible pump manufacturers to eliminate the use of oil for the electrical insulation of pumps’ motor. For this purpose, we studied a proper resin dispensing equipment for this application, in order to guarantee a great hourly production for any pump size.
In this specific case the combination of resin and process has been particularly well set up. It’s very important to obtain a perfect dispensing without any voids and also to not have dimensional deformation of the metal housing. The choice of the right epoxy resin, with the correct Tg value, will guarantee an optimal result in the mechanical properties, thus dimensional stability. The resin viscosity is also very important for perfect filling of each unit and its reaction speed has to be suitable for a continuous operation in production.
