Maintenance and repair costs (Cm)

The calculation of the life cycle cost of a pump system includes the total cost of maintaining and repairing the system over its lifetime.

The primary costs related to maintenance and repair of a pump system are:

  • Labour cost
  • Spare parts
  • Transportation
  • Cleaning

Carrying out routine maintenance is recommended as a way to prevent breakdowns and extend the working life of a pump.

Grundfos has made some estimates on the cost of maintenance for different types of pump.

Examples:

Wet-runner pumps
Maintenance-free for a period of 10 years

Dry-runner pumps
Expect to replace the shaft seal three times and the motor bearings four times during the normal lifetime of 20 years.

The estimated lifetime cost of maintenance and repair amounts to a total of approx. 5 %.
