Tsurumi Pumps have a reputation for making some of the best submersible pumps in the world. But even the Tsurumi submersible pumps can suffer a shortening of life cycle and efficiency when exposed to aggressive media such as salt water.
One of the more common strategies for fighting corrosion is to retrofit anode blocks while replacing parts. This is necessary because even pumps made of supposedly rustproof materials like stainless steel are susceptible to corrosion when exposed to aggressive media on a daily basis.
Stainless steel is corrosion-resistant because it has a thin layer on the top called the “passive layer.” It is self-repairing, though on a limited basis, due to its molecular structure. However, that thin layer can be eroded, exposing the cast elements beneath it.
Those cast metals are susceptible to corrosion. The only material that is close to being 100% trustworthy and resistant to corrosion is titanium. Basically, the more aggressive the material in which the pump is sitting, the greater effect it can have on the metal on the outside of the pump.
The Tsurumi Pump Solution
Tsurumi has a solution for fighting corrosion in submersible pumps: retrofittable sacrificial anodes. They are solid place which are made of zinc or aluminum. The anodes are attached to the casing with screws. This causes what Tsurumi calls a bimetal corrosion process. In a bimetal corrosion process, the less worthy metal is the one affected by the corrosion while the more hearty metal is not.
The end result is that the superficial anodes become rusty while the functional parts of the pump are almost totally unscathed by corrosion.
