Product Detail

High Quality Marine CLZ Vertical Centrifugal Pumps

CLZ series of pumps is suitable for various marine systems and can be used as bilge pumps, ballast pumps, and fire pumps. They are also applicable in seawater or freshwater cooling systems as well as domestic water supply systems, meeting the operational needs of vessels under different sailing and working conditions. For large-size models, the CLZ pump can serve as a high-efficiency supply pump for anti-smuggling water cannons and fire monitors, offering powerful and stable water delivery—an ideal supporting unit for emergency response and specialized marine operations.

Our CLZ vertical centrifugal pump is capable of withstanding high-temperature liquids up to 80°C, demonstrating excellent stability and safety under demanding conditions. Certain models are further designed for petrochemical pipeline transport, meeting the requirements for continuous delivery of high-temperature and highly corrosive media, thereby offering users a broader range of application scenarios.

Specialized Design Features:

  • Upgraded Cyclone Separator Technology: A cyclone separation structure is integrated at the high-pressure end to effectively remove impurities and air bubbles from the medium. This significantly improves system cleanliness and extends the mechanical seal service life by more than 2 times, while greatly reducing maintenance frequency and replacement costs.
  • vice life by more than 2 times, while greatly reducing maintenance frequency and replacement costs.
  • Intelligent Impeller Cutting and Grading Technology: Models with suffixes A/B/C correspond to different levels of impeller cutting configurations. These allow for precise adjustment of flow rate and head based on actual operating conditions, enabling customized fluid control and enhanced delivery efficiency.
  • Multi-Standard Flange Interface Design: By default, the product is equipped with GB9113.3/GB2505 marine flange standards, while also supporting customization for ANSI, DIN, and other international flange standards. This ensures excellent system compatibility and engineering adaptability worldwide.
