DESIGN VARIANTS
The pumps are outfitted with a foot heating (H4). This can be realized either separately or in conjunction with a bypass line. The heating system is rated for operating pressure of 16 bar at 200 °C (steam) or 6 bar at 350 °C in the standard construction. It can also be used for cooling.
The thermal barrier (W) reduces ball bearing temperatures in the gearing when hot liquids are being transported.
