Nowadays, the marine or shipbuilding industry is largely concentrated in Asia, namely South Korea, China, and Japan. Besides general cargo ships and container ships, freighters and tankers for chemicals, crude oil and other materials, cruise liners as well as yachts and other smaller ships & boats are also being built in increasing numbers.

Although the production of ships is dominated by these countries, the decisions on building and equipping the ships is often made in other countries by the owners, shipyards, operating companies or even investors.

Since the travel routes of the ships encompass the entire globe, the ships and their equipment must meet different legal requirements. In addition, the owner determines to which certification the ship should be certified. This requires a high degree of flexibility on part of the suppliers. After commissioning the ships, a high level of flexibility in service and worldwide availability of spare parts is expected of the suppliers of marine pumps in order to utilize the narrow service windows in harbors and to move the spare parts on board.

Application areas for marine pumps

Pumps can be found in all types of applications throughout the entire ship. The most important locations are in the engine room, where the fuel and oil is pumped to the motors and numerous lubricating and hydraulic pumps for all types of different sets of machines are used. Furthermore, water for operating and cooling the machines and units is also delivered.
 

Pumps for the water supply on ships

The next highly important areas are water supply and water treatment. In these areas, the generated and delivered quantities on cruise liners are considerably higher due to much higher number of passengers compared to freighters, which are under way with a small crew. But these, too, have areas where pumps are required, such as the treatment of seawater and bilge water, wastewater or ballast water treatment.
Tankers in particular have pumps for loading and unloading as well as pumps for fire protection. There are many additional tasks for pumps on all types of different ships.
