Product Detail

Best Marine CIS Series Horizontal Centrifugal Pump for Sale

The CIS Series Marine Horizontal Centrifugal Pump is a single-stage, single-suction horizontal pump specifically engineered for marine and offshore applications. With outstanding structural compactness, corrosion resistance, and system adaptability, it is widely used in cooling systems, ballast water transfer, domestic water supply, and wastewater discharge on various types of vessels.

  • Key Design Features: The pump adopts a space-saving horizontal layout, with the pump body arranged horizontally to maximize space efficiency in the engine room. Its clockwise rotation at the drive end is fully compatible with conventional ship power transmission systems, ensuring seamless integration and smooth operation.
  • Materials & Corrosion Resistance: The standard configuration includes a bronze impeller, stainless steel shaft, and high-performance mechanical seal, providing excellent corrosion resistance. It is suitable for continuous handling of seawater, freshwater (temperature ≤75°C), and lightly contaminated domestic wastewater, ensuring stable operation and long service life in marine environments.
  • Sealing System & Flange Standards:The pump features an advanced mechanical sealing system designed to effectively prevent leakage, improving operational safety and equipment reliability. Flange connections conform to marine standards, including GB, DIN, and ANSI, and custom flange sizes and pressure ratings are available to meet various pipeline standards and operating conditions worldwide.
  • Performance Range & Motor Configuration:The CIS pump offers a wide performance range, with flow rates from 3.7 to 460 m³/h and head from 4 to 125 meters, making it suitable for both small-scale and large-scale marine applications. It is equipped with a high-efficiency IE3 motor as standard, with power ratings from 0.55 to 75 kW, ensuring both energy savings and high performance.
  • Pressure Rating & Structural Strength: The pump casing is made from high-strength cast iron with a maximum pressure rating of 1.6 MPa. For more demanding conditions, an optional cast steel version is available, capable of handling pressures up to 2.5 MPa, making it ideal for high-pressure systems and harsh marine environments.

Customized Horizontal Centrifugal Pump

  • Impeller Trimming & Grading: Model suffixes “A/B/C” indicate different levels of impeller trimming, allowing for precise customization of flow rate and head to meet specific operating conditions. Impellers are precision-machined using CNC equipment, followed by dynamic balancing tests to ensure smooth operation. The residual unbalance is controlled within ≤2.5 g·mm/kg, effectively extending the service life of bearings and seals.

  • Flange Compatibility: The pump supports a wide range of marine-standard flanges, including GB, DIN, and ANSI, and allows for reducing flange connections with a maximum allowable reduction ratio of 1.5:1 to suit various piping configurations. Flange materials are available in carbon steel (standard), 316L stainless steel, and duplex stainless steel. Anti-corrosion coating options such as epoxy resin or PTFE can be applied to enhance durability and reliability in seawater or corrosive environments.
