Overview
- Reduces galvanic corrosion by e.g. sea water
- Complements good coating of exposed metal surfaces
- Available for Flygt submersible pumps and mixers
- Anodes must be replaced well before they have been consumed by the corrosive action of the water
Corrosion protection with zinc anodes
Zinc anodes are bolted to Flygt pumps and mixers to improve protection against galvanic corrosion by e.g. sea water. The weight and positions of the anodes are chosen carefully for each Flygt pump and mixer model.
The pump/mixer should have special coating as the main protection. This includes careful sand blasting of the surface followed by good quality epoxy painting. Special coating is a factory option for Flygt pumps and mixers.
The area around the pump or mixer installation should be as free from exposed steel or stainless steel surfaces as possible. Those surfaces increase galvanic corrosion.
A correctly designed and applied protection will cut corrosion damage to a minimum.
The protection must be maintained as follows:
- Add a new layer of paint if the surface has been damaged.
- Replace the zinc anodes well before the zinc is consumed by the corrosion.
Wet Pit (P)
Semi permanent, submersible pump installation. Wet pit arrangement with the pump installed on twin guide bars with automatic connection to the discharge pipe.
Column (L)
Column pipe, semi permanent, submersible pump installation. Wet pit arrangement with the pump installed inside the discharge pipe, automatically seated on a flange.
Portable (F)
Free standing, semi permanent, submersible pump installation. Free standing pump with connection for discharge hose or pipe in sumps with restricted space.
Portable (S)
Portable, submersible pump installation. Portable pump with hose coupling or flange for connection to the discharge pipe.
Dry Installation vertical (T)
Vertical, permanent, dry pump installation. The submersible pump is installed in a dry pit, with flange connection to suction and discharge piping.
Dry Installation (Z)
