FAQ
Q: What is the maximum seawater temperature the pump can handle?
A: The marine dredging pump is designed for seawater temperatures ranging from -2℃ to 35℃, covering most marine dredging environments.
Q: How often should the anti-corrosion coating be inspected?
A: The coating should be inspected every 6 months of operation or after any impact damage, with touch-up painting recommended when more than 5% of the surface area shows coating degradation.
Q: Can the pump be used for dredging in shallow coastal waters?
A: Yes, the pump can be configured with a shallow-water suction head for operation in water depths as low as 2 meters, making it suitable for coastal dredging projects.
