Product-specific basic repair kits are available for most Flygt pumps and mixers. Each kit contains the parts needed for an overhaul of the drive unit. This includes main and support bearings, inner and outer mechanical seals, and a complete set of O-rings. Certain sets also contain parts needed for a major overhaul of the drive unit such as washers and circlips. Necessary instructions for correct mounting are delivered with the kits.
