Horizontal Ring Section Multistage Centrifugal Stainless Steel Sea Water Pump DF46-50X4
Description
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 seawater-resistant pumps. Sanchang 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.
While the pump is running, the galvanic anode does not protect rotating parts. 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 special cast iron impeller" suited to protect the shaft against corrosion by seawater.
This material is made by specially treating chromium cast iron.
Because its electric potential is slightly lower than that of the
shaft, the impeller corrodes gradually, which helps to prevent the
shaft from corroding. The impeller needs to be replaced every few
years to 10 years, depending on operating conditions. However, the
impeller costs far less than the shaft to replace.
