In the previous post, we explained the most common problems that usually arise with centrifugal pumps and their possible causes. And we mentioned the importance of carrying out regular preventive maintenance to prevent these problems, as far as possible. But how do we carry out maintenance on a centrifugal pump, and what do we need to look out for? We will tell you about it below.

Maintenance of each part of a centrifugal pump

It is advisable to check some critical points daily and every few months, and to carry out more exhaustive checks once a year. Let’s see how to check each part of a centrifugal pump.

  • Bearings: we have to check their temperature, if there are vibrations and how is the lubricant level.
  • Suction and delivery pipes: we have to detect possible leaks and clogging.
  • Shaft seals: we have to look for leaks and retighten the packing, as well as check the cooling water flow.
  • Ball bearings: we have to check the oil level in the body, its temperature and excessive noises and vibrations.
  • Impeller: we have to check the looseness between the impeller and the casing and adjust the looseness if necessary.
  • Motor: we have to check the temperature.
  • Electrical connections: we have to check that they are in good condition.

Spare parts needed to maintain a centrifugal pump

In order to perform maintenance on a centrifugal pump, we will need to have several spare parts such as the following:

  • Mechanical seals.
  • Seal sets.
  • Wear plates.
  • Pump shafts.
  • Ball bearings.
  • Complete couplings.

In addition to spare parts, we must always have consumables such as lubricants and oils, as they must be renewed from time to time.

How to carry out maintenance on a centrifugal pump

To carry out periodic maintenance, it is not necessary to disassemble the pump, as it is enough to carry out an inspection at a glance. However, it may be necessary to carry out a more thorough inspection in order to replace damaged or worn parts.
