Seawater pumps are indispensable to waterfront development projects and aquaculture facilities. Japan is a maritime nation with the sixth longest coastline in the world. Tsurumi has performed field tests in various marine construction projects under severe conditions over many years, in collaboration with general contractors, and applied the obtained know-how to developing submersible seawater-resistant pumps. Tsurumi also considers economic efficiency important and, therefore, designs pumps with "as many standardized materials as possible."
Tsurumi's standard pumps can be combined with a seawater-resistant kit (optional) that adds a "galvanic anode" and "seawater-resistant special cast iron impeller," to solve both problems of long service life and cost efficiency.
