Routine inspection and maintenance can avoid unnecessary and expensive downtime as well as operating costs. It is recommended to regularly check:

  • - If the pump functions properly – excessive noise levels may indicate wear problems to bearings and gears, dragging of screws on the pump casing or cavitation.
  • - Pressure and Flow of the flushing system, if present
  • - Temperature of the heating / cooling system, if present
  • - Oil level in the gearbox – at standstill the oil level must be in the centre of the visual level indicator

Routine inspection and maintenance can avoid unnecessary and expensive downtime as well as operating costs. It is recommended to check the following on a daily basis:

  • - That the valve in the suction pipe is completely open
  • - That the inlet pressure is not too low in order to avoid the occurrence of cavitation
  • - The delivery pressure is in line with system requirements
  • - That the shaft seals are not leaking.
  • - Pressure and Flow of the flushing system, if present
  • - Temperature of the heating / cooling system, if present

For IG & IGH Variants periodically check the bearing oil levels. The oil must be changed annually or after every 5000 operating hours.
