Horizontal Ring Section Multistage Centrifugal Stainless Steel Sea Water Pump DF25-50X3
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.
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 submersible seawater-resistant pumps. Tsurumi also considers economic efficiency important and, therefore, designs pumps with "as many standardized materials as possible."
Sacnhang'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.
Structure Design
* By adopting precision casting and unique throttling and pressure reducing devices for auxiliary support pump vibration and noise are greatly reduced and service life is prolonged.
* Excellent hydraulic model and design, unique first stage double suction impeller, forging casting, reliable anti-abrasive materials make sure the pump with excellent NPSH, pump work steady, no noise and users do not need to add preposition pump or inrease the height of the inlet chest.
