Daily And Periodic Inspection; Changing The Mechanical Seal Sump Oil - Zenit UNIQA Anleitung

First installation manual – Translation of original instructions

7.4 Daily and periodic inspection

Interval
Daily Measuring the operating current:
- To be within the rated current
Measuring the power voltage variation:
Continuous running duty = within ± 5% of the rated voltage
Intermittent periodic duty = within ± 10% of the rated voltage
Monthly Measuring the insulation resistance:
Insulation resistance reference value = 20 MΩ minimum
NOTE: The motor must be inspected if the insulation resistance is considerably lower than the last inspection.
Half-yearly Inspection of lifting chain or rope:
- Replace if damage, corrosion, or wear has occurred to the chain or rope.
- Remove if foreign object is attaching to it.
EN
Yearly Inspecting cables, oil, mechanical seals, bearings, wearing
parts (impeller, suction flange....).
NOTE: rubber parts need to be replaced if disassembled
during inspection
Once every 2 ye- Changing oil

for heavy duty Changing the mechanical seals
Once every 2 to 5 Overhaul:
years The pump must be overhauled even if the pump appears normal during operation.
Especially, the pump may need to be overhauled earlier if it is used continuously.
