Product Overview
Marine Horizontal Self-Priming Centrifugal Pump
The CWZ series horizontal self-priming centrifugal pump is engineered specifically for marine environments, including cabin bilge cooling and firefighting operations. Designed for reliability, this pump efficiently handles seawater (up to 80°C), fresh water, and other non-eroding liquids. Its horizontal configuration ensures simplified installation and maintenance, while the self-priming capability allows for effective fluid transfer from below the pump level.
