Pumps and Plate Heat Exchangers for the Marine and Offshore Industry

Whether you are on board a cruise ship, a container ship or an oil rig, reliability is crucial on the open sea. We supply high-quality, reliable marine pumps and plate heat exchangers.
In recent years, the maritime industry has become more focused on environmental impact and makes high demands on product’s energy efficiency and CO2 emissions. That is why we customize our pumps and plate heat exchangers. When we calculate a product, we consider all factors to ensure ideal pressure loss and flow rate, ensuring the solution remains energy efficient and environmentally friendly.

- Heat exchanger for central heating
Plate heat exchangers for seawater
Plate heat exchangers for the marine industry are primarily used for cooling diesel engines, lubricating oil and gear oil, as well as for central heating systems.
To ensure optimal performance when the seawater flows through the plate heat exchanger, it is crucial to provide the best working conditions. Therefore, we recommend using plates made from titanium to extend their lifespan and minimize corrosion when processing saltwater.
Titanium is typically the preferred material for seawater-cooled heat exchangers due to its exceptional corrosion resistance, even in hot, aerated seawater. Additionally, it offers good strength and low density, making it an ideal choice for marine applications.


Pumps for the Marine Industry
For more than 20 years, we have supplied high-quality marine pumps to the marine and offshore industries. Over the years, we have delivered pumps to both large container ships and smaller fishing vessels worldwide. DanPump’s centrifugal pumps are available for various applications, including ballast, bilge, boiler, and fire pump systems.
To withstand the harsh conditions encountered in the marine and offshore environments, our marine pumps can be supplied with bronze pump housing and impeller. Bronze is a highly durable material, that allows the pump to handle demanding liquids such as salt water while reducing corrosion.
Our DanPumps product range is modular, featuring many common components, which ensures a quick and efficient supply of spare parts.
