What methods does everyone have for preventing freezing? The pump on site is badly damaged.
Waste steam can be introduced by enclosing the pump.

Methods of preventing freezing include electric heating, steam heating, and continuous water flow
In the north, indoor anti-freezing measures are generally adopted, along with steam tracing or electric heating – this is currently the best approach, as it requires less investment!
Pumps that are in operation will not be damaged by freezing; for standby pumps, it is sufficient to fully close the inlet and outlet valves and open the drain valve at the pump’s outlet.
As a few classmates upstairs said, as an additional point: when preventing freezing of critical equipment, it is necessary to turn such equipment manually every half hour. Keeping the pumps running with a gentle flow of water is key to preventing freezing, but the flow rate should not be too high, as that would constitute a waste of resources!
