3: Why does a cooling system using propylene glycol require pumps with oversized motors?
Because the viscosity and density of propylene glycol is higher than tap water.
3: Why does a cooling system using propylene glycol require pumps with oversized motors?
Because the viscosity and density of propylene glycol is lower than tap water.

3: Why does a cooling system using propylene glycol require pumps with oversized motors?
Because propylene glycol has a lower specific heat capacity and therefore requires a higher flow.

5: How do you prevent pumps from malfunctioning when transporting hot water with a temperature above 120C°?
Equip the pump with either single shaft seals designed to keep hot water away from the deal, double-shaft seals that are actively cooled, or use air-cooled tops to insulate the seal chamber.
5: How do you prevent pumps from malfunctioning when transporting hot water with a temperature above 120C°?
Isolating the pump and install heat tracing.
