Polaris pumps and motors are basically composed of a gear housing in aluminium.
As Tranaformer oil has more wax content, it has higher pour point. I talk to Exercise 1: Some people think that the zone defense is always a passive one. Paraffin-based oil has a higher value of pour point, compared to Naphtha transforker oil, but in Rtansformer like country, it does not affect the use of Paraffin oil due to its warm climate condition.
