marine vertical fire pump which is multistage centrifugal pump

The marine vertical fire pump is engineered for installation in shipboard firefighting piping systems, delivering water to fire sources via nozzles or sprinklers. Its compact vertical design optimizes space usage, making it ideal for marine environments with limited installation area.

Technical Parameters

1. Flow range: 16 to 24 m³/h
2. Head range: 32 to 254.8 meters (see technical chart for details)
3. Number of stages: 2 to 14 (see technical chart for details)
4. Rated speed: 2,840 to 3,560 rpm (see technical chart for specifics)

Main Features

1. Vertical design: Space-saving structure for simplified shipboard installation
2. Multi-stage pump body: Delivers higher head and larger flow in compact space for long-distance water spraying
3. High pressure output: Ensures water reaches higher floors and remote areas from the pump room
4. Corrosion resistance: Manufactured from stainless steel or cast iron to withstand seawater corrosion
5. High reliability: Quick start and stable operation in emergencies, often equipped with automatic start systems and standby power

Applications

1. Marine fire protection: Provides water supply for ship fire prevention and extinguishing systems
2. Preventing fire at sea: Delivers sufficient pressure and volume for fire control on ships and offshore platforms

Structure and Material

1. Pump casing: Made from cast iron or stainless steel for enhanced corrosion resistance
2. Impeller: Stainless steel, precision stamped for high performance and durability
3. Mechanical Seal: Wear-resistant design for leak-free operation

Maintenance and Care

1. Regularly inspect pump body and mechanical seal for wear or leakage
2. Keep pump interior clean to prevent performance-impacting impurities
3. Test starting performance and working pressure regularly to ensure system readiness
