The maritime industry is facing an environment full of uncertainty. With increasingly stringent emission regulations, fluctuating fuel prices, and the difficulty in predicting which technology will become mainstream, shipowners and vessel operators need more confidence in their investment decisions.
Sailing on alternative fuels such as LNG, ammonia, methanol, and LPG is one of the most effective ways to reduce a vessel’s environmental footprint and ensure long-term compliance. However, for the industry, finding a fuel pump solution that can handle the extreme properties of these liquids and adapt to different fuel types without pump modifications has been a major challenge.
Introducing the new DesFuel Deepwell Pump
DESMI’s DesFuel Deepwell Pump changes this. As the world’s first marine fuel pump designed from the ground up to be compatible with all alternative fuels, it is the optimal solution for gas system suppliers, shipowners, shipyards, and engineering companies seeking reliable performance and stability, on-time delivery, and global technical support.
The new pump’s design fully considers current market demands, drawing inspiration from DESMI’s cargo gas pumps, which have been widely proven in the global maritime industry since 1996 and are renowned for their excellent performance and reliability.
As a deepwell pump, the DesFuel Deepwell Pump demonstrates significant advantages over other solutions:
Key components located outside the fuel tank: Facilitates maintenance, reduces costs, eliminates the need for special parts or materials, enhances reliability, reduces reliance on specialized skills, and minimizes additional heat in the /cargo tank (reducing boil-off gas to a minimum). Components can be easily accessed without first emptying the fuel tank, greatly simplifying maintenance.
Maintenance without gas-freeing: The pump and drive shaft are installed within a caisson pipe that can be isolated from the fuel tank. The entire pump can be removed, serviced, and reinstalled without time-consuming and costly gas-freeing operations.
No filtration unit required: The motor is air-cooled, and the main bearings are lubricated by oil, not the fuel itself. This means the pump does not require a filtration unit to remove fuel impurities, thereby avoiding the high maintenance costs and downtime associated with filter clogging.
Optimized for low NPSHr: The pump’s design is optimized using advanced CFD tools to achieve high efficiency and extremely low NPSHr, thereby improving performance at low fuel tank levels.
Suitable for various vessels and fuels: The pump is available in five sizes, covering all ship types, with a wide operating range that adapts to different engine loads, reducing recirculation needs and minimizing boil-off gas emissions. This pump is compatible with all current and future fuels without requiring additional modifications.
Process optimization: This pump not only supports fuel flexibility but is also easy to install and compatible with fuel gas systems. DESMI provides global team support, including all necessary documentation, warranties, after-sales packages, and service agreements.
A Trusted Solution and Service
The DesFuel Deepwell Pump was designed and developed by DESMI engineering experts. Each pump is manufactured at the production base in China, close to shipyards, effectively reducing transportation time and emissions, thereby offering customers opportunities for shorter lead times and optimized cash flow. Furthermore, keeping production and delivery requirements within the region often simplifies and speeds up the contract approval process.
Like all DESMI products, the DesFuel Deepwell Pump is supported by a reliable global service network. With 190 years of industry experience, DESMI ensures that customers and partners across the value chain receive round-the-clock, local technical support and spare parts services.
In a maritime industry full of uncertainty, the future is unpredictable. However, with the DesFuel Deepwell Pump, shipowners and operators can be assured of having the most flexible, economical, and highly reliable alternative fuel pump solution on the market, preparing their vessels and businesses for any future challenges.
