Tsurumi Pumps have been making high quality pumps since they were established in 1924, in Japan. Their submersible pumps have a reputation as being among the best in the industry. But there is one niche in which they have everyone beaten hands down: submersible seawater pumps.
Tsurumi designs their submersible pumps in a manner that helps them handle virtually any liquid. This includes corrosive liquids, hot water, wastewater and seawater. The durability of Tsurumi pumps and their ability to handle so many different media is just one reason why they hold such a high stature in the industry.
The Tsurumi solution to the problem of corrosive liquids is to build their pumps out of titanium. Any part that comes into contact with liquids on any Tsurumi submersible pump is made out of titanium to keep them from corroding and to give them a longer life.
Tsurumi TM-Series Submersible Seawater Pumps
The Tsurumi TM Seawater Pump series combines titanium with specially formulated resins that are also resistant to seawater. Since titanium is so expensive, Tsurumi uses the resins as a way to lower the cost of their seawater pumps while still providing the highest quality in the business. The end result is a pump that is reliable, efficient and cost-effective.
Seawater is Difficult to Handle
Because seawater is so corrosive, it is necessary to take countermeasures when building submersible pumps to transport it. If precautions are not taken, the seawater can cause corrosion, pump damage and even pump failure.
Other pump manufacturers tend to use stainless steel as a material and coated castings. However, stainless steel pumps suffer from localised corrosion, while the coating tends to peel off coated castings with prolonged use. Ultimately, most submersible pumps suffer from short service lives when being used for see water.
Many operations and manufacturers are still using stainless steel pumps for seawater, but the aforementioned corrosion ends up increasing the costs greatly. Stainless steel forms a chromium oxide coating on the surface, but in the absence of sufficient oxygen, the surface degrades and corrodes quickly.
Marine organisms or packing can often cause degradation of stainless steel pumps. Once the surface is compromised, water eventually ends up in the motor and the pump fails. The main takeaway here is that stainless steel pumps are not fully resistant to seawater.
In experiments that Tsurumi have conducted on stainless steel pumps, they have found that degradation begins usually within six months. We don’t feel that is a long enough service life for any pump.
Why Tsurumi TM-Series Pumps are the Industry Standard for Seawater
Tsurumi submersible sea water pumps feature a combination of titanium and resin. This allows Tsurumi pumps to transport seawater with no corrosion or degradation of any part of the pump.
Tsurumi’s resin components are specially designed so that each individual part is made of the resin that is most likely to prevent the pump from corroding.The end result is a pump that has a much longer service life than those made of stainless steel or standard resin materials.
Tsurumi submersible seawater pumps can be used for intake, draining and circulation purposes. The lubricating oil is made out of food grade paraffin. This makes it fish friendly and 100% safe for operations involving fish, such as water tanks, fish preserves and fish farms.
Tsurumi submersible sea water pumps offer discharge bore diameters from 40 to 80mm. Motor capacities start at 0.25 kilowatts and go up to 3.7 kilowatts. Single phase pumps are available up to 0.75 kilowatts. There are also models available that operate automatically.
