Marine fire pumps provide water to extinguish any fire on board.
These pumps deliver seawater or foam to quickly extinguish fires before they get out of control.
Most ships need to be equipped with several of these devices. It is essential to have a fire protection system on board.
Fire pumps are part of the fire sprinkler system water supply and are powered by electricity, diesel or steam. The pump inlet is either connected to a fresh supply line or to a static water source (on a boat this will be sea water). The pump provides water flow at higher pressure to the sprinkler system riser and hose riser.

Double-suction Pumps VS Single-suction Pumps
Difference 1:
The flow rate is different. The single-suction pump has a small flow rate, while the double-suction pump has a large flow rate.
Difference 2:
The structure is different. A single-suction pump means that there is only one impeller in the pump, and single-suction means that water is sucked from one side of the impeller. A double-suction pump consists of two impellers placed back to back, with water flowing from the impellers into a volute.
Difference 3:
Different application scenarios. Single suction pumps are the most common type of water pump used in agriculture. Double-suction pumps are mostly used for water supply and drainage in mines, cities, power stations, and various water conservancy projects.
Routine maintenance of Fire Water Pump
Regular maintenance of fire pumps is essential to ensure they function optimally in providing adequate water pressure for the sprinkler system.
Weekly checks can be performed by on-site staff, while professionals specializing in fire safety should conduct monthly, annual, and long-term inspections and maintenance.
Following NFPA 25 guidelines, fire pumps undergo both monthly 'churn' tests and annual performance testing to verify their proper functioning.
