Maritime engineers and crew members rely on reliable and efficient pumping solutions to maintain vessel operations, ensuring smooth water circulation and management. DESMI's Modular S Serie is designed to meet these demands with a robust centrifugal pump platform that offers versatile performance. This series can handle flows ranging from 100 to 3000 m³/h and can operate with both sea water and fresh water, making it suitable for a wide range of marine applications. The modular design allows for easy customization with various DN sizes from 100 to 300 mm and supports a range of materials, ensuring durability and flexibility. With over 140 variants available, the Modular S Serie has been a trusted choice since 2010. Common issues such as mechanical seal leakage and bearing wear can be mitigated through regular maintenance, with service intervals recommended at 8000 hours for seals and 20000 hours for bearings. The series’ interchangeable parts further streamline maintenance and reduce spare parts inventory, enhancing operational efficiency.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
