Description
Product
Seawater is typically supplied via an engine-driven pump to keep a marine engine cool. A device used to move or circulate seawater is a seawater pump. It is frequently used on a marine vessel for various general service functions like water circulation systems and dewatering activities where the working area is constrained and needs to move quickly. These marine seawater pumps are used for various purposes, including ballast pumps, oceanic cooling, and bilge pumps. Key Features:
- Transports water from the engine’s heat exchanger to the intake strainer.
- It is also possible to use desalination, the procedure for extracting minerals and salt from seawater.
- For high-pressure deck cleaning and bilge dewatering.
- More significant water flows are delivered, superior at moving low-viscosity liquids like seawater.
- It fits Alpha One, Alpha Gen II, Brao, SSM, and Dry Six drive water pumps for MerCruiser V8 engines with 200-575 HP.
