Vertical Marine Seawater pump

Product Introduction The Series is a high-performance vertical inline pump, specifically engineered for the rigorous demands of marine and offshore applications. It combines the exceptional space-saving benefits of an inline design with the robust, corrosion-resistant materials required for reliably handling seawater. This makes the pump the ideal choice for critical duties like engine cooling, ballast transfer, and fire-fighting systems aboard ships and on offshore platforms, where both performance and durability are paramount.


Design Philosophy & Construction The pump is designed from the ground up to withstand the harsh, corrosive environment of the sea.

  • Seawater-Resistant Materials: Unlike standard pumps made of cast iron, all wetted components of the series—the casing, impeller, and shaft—are constructed from materials with excellent resistance to saltwater corrosion. Standard materials include Marine Bronze, Ni-Al Bronze, and Duplex Stainless Steel, ensuring a long, reliable service life without succumbing to rust or pitting.
  • Space-Saving Inline Configuration: The pump’s vertical inline design is a major advantage in the crowded engine rooms of a vessel. By fitting directly into the pipeline, it occupies a minimal footprint, freeing up valuable floor space for other equipment and providing easier access for crew.
  • Marine-Duty Motor and Seal: The pump is equipped with a high-quality marine-duty motor, which is specially designed to handle the humidity, vibration, and specific power requirements found on a ship. A robust, hard-faced mechanical seal is used to prevent leaks and withstand the slightly abrasive nature of raw seawater.

Key Features & Benefits

  • Maximum Seawater Corrosion Resistance: The specialized bronze or duplex stainless steel construction provides superior protection against saltwater, ensuring maximum durability and pump life.
  • Saves Critical Onboard Space: The vertical inline design offers an extremely compact footprint, making it perfect for installation in tight ship engine and machinery rooms.
  • Simplified Piping & Installation: Reduces the complexity of pipe runs, saving on materials and labor costs during shipbuilding or retrofitting.
  • Built for Marine Reliability: The heavy-duty construction, robust motor, and durable seal are designed to withstand the constant vibration and motion of a vessel at sea.
  • Easy to Service: The back pull-out design allows the motor and rotating assembly to be removed for maintenance without disconnecting the pump casing from the pipeline, a critical feature for onboard repairs.

Common Applications The pump is the workhorse pump for a wide range of essential shipboard and offshore services:

Offshore Platforms: Used for a variety of seawater supply and circulation duties on oil and gas rigs.

Marine Engine Cooling: The main pump for circulating seawater through central coolers for the main engine, generators, and other auxiliary machinery.

Ballast and Deballast Systems: Rapidly pumping seawater into or out of ballast tanks to trim the vessel and maintain stability.

Marine Fire-Fighting Systems: Serving as the main pump to supply high-pressure seawater to the fire main, hydrants, and sprinkler systems.

General Service & Deck Wash: Providing a ready supply of seawater for cleaning, deck washing, and other utility purposes.
