Sea water pumps are indispensable to waterfront development projects and aquaculture facilities. Sanchang 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 seawater-resistant pumps. Sanchang also considers economic efficiency important and, therefore, designs pumps with "as many standardized materials as possible."
Our Horizontal Ring Section Multistage Centrifugal Stainless Steel Sea Water Pump is a utility-grade, high-pressure, ring section pump with heavy duty, segmental ring, diffuser design. Axial thrust balance device with stacked rotor construction. All wet parts could be customized according to different kinds of chemical property. Galvanic Metal, Stainless Steel, Duplex Stainless Steel, Bronze all could be customized according to clients' requirement.
In seawater applications, the materials of the shaft and impeller must be carefully matched to avoid shaft corrosion and expensive repairs. After long years of research, Sanchang developed an exclusive "seawater-resistant configuration" suited to protect the shaft against corrosion by seawater.
