107 Accessories 8’’WPS® Cooling Shrouds The cooling shrouds are designed to ensure a sufficient flow velocity past the motor in order to provide sufficient cooling. For the following cases a cooling shroud is recommended: • horizontal or vertical installation in a tank • installation of the pump in the screen from the well • installation in big sized well not ensuring enough cooling velocity. See table. To the shroud itself, a screen can be added. In case of horizontal installation a set of supports are available. Minimum flow required for motor cooling in water up to 20°C.
