Check bearing housing temperature: it should never exceed 70°C. If this happens, check group alignment or
remove bearing housing cover as the cause might be an excessive amount of grease or a failed bearing.
If a danger of frost exists, drain the pump completely during idle periods by unscrewing the draining plug
(see picture aside). Fill then the pump again as described in sect. 5.1.
6.2 Pump stop
Before any stop it is necessary to:
- Switch off the line voltage
- Close suction and delivery gate valves
- Drain the pump through the hole on the lower side of the pump casing.
