Horizontal, single-stage single-suction centrifugal pump engineered to ISO 2858 for marine use. Designed for handling fresh water and seawater as cooling, circulation, booster and general-service pumps aboard vessels. The CIS range supports routine shipboard duties including bilge and ballast transfer, deck wash, firefighting support and general service duties where a rugged, ISO-compliant centrifugal pump is required.
Key features
- Construction: horizontal, single-stage, single-suction centrifugal design (CIS type) built for marine environments.
- Materials: pump case available in cast iron or stainless steel; impeller options in cast iron or bronze; shaft in stainless steel. Special material combinations available for higher-temperature or more corrosive service.
- Sealing: mechanical seal or gland (packing) seal options to suit application and maintenance preferences.
- Temperature range: standard rated for liquids up to 80°C. With special materials and seals, service up to 120°C is possible.
- Pressures: maximum suction pressure 0.3 MPa; maximum working pressure 1.6 MPa.
- Drive / motor options: compatible with standard marine electrical supplies – 380 V / 440 V at 50 Hz / 60 Hz; typical nominal speeds offered include 1,450 / 1,750 and higher-speed variants (approx. 2,900 / 3,350 rpm) depending on motor selection.
- Standards: Designed to ISO 2858 for interchangeability and system integration.
Typical applications
- Engine-room cooling and circulation pumps
- Freshwater service and pressure boosting
- Bilge and ballast handling
- Fire-fighting and emergency service pumps (as part of a matched system)
- Deck wash and general service duties
Notes for specification and ordering
Provide required model (e.g., CIS100-80-125), required flow and head (TDH), operating fluid and temperature, preferred materials (case/impeller/shaft), seal type (mechanical vs. packing), motor voltage/frequency and rotation direction. Performance curves, dimensional drawings and spare parts lists are recommended to confirm selection for shipboard installation and system compatibility.
