For pumps that are not in use during winter, how can the liquid inside the pump chamber be emptied? The pump itself doesn’t have a drain outlet. Is there any convenient way to deal with this? Thank you everyone.
Just weld a relief valve under the inlet pipe
The gas is blown out through the nearest outlet.
Release and blow twice – there’s no good way around it.
There is a plug at the bottom of the pump; turn the plug off to drain the water.
If there is no plug at the bottom of the pump, then antifreeze can only be poured in. We have tried various purging methods, and residue always remains
Just disconnect the connection at the imported pipeline.
