Injection pumps for liquid green fuels
Marine propulsion systems are mainly driven by fossil fuels. This leads to the global marine industry contributing to climate change and global warming with large amounts of CO2. In 2018, the International Maritime Organization (IMO) decreed that international shipping should become CO2 neutral by 2100. The currently best proven and immediately available technology is the replacement of fossil fuels with CO2 neutral green fuels such as methanol. New combustion engines can be equipped with this technology, existing ones can be converted.

Substitution of fossil fuels by green fuels
Green fuels include the following fuels, which can be pumped with Hammelmann injection pumps:
- Methanol (MeOH, CH3OH, CH4O)
- Ethanol (C2H6O)
- Ammonia (NH3)
Built on proven technology
The materials used and the design of the system are optimized for continuous operation. The upright design minimizes the mechanical stress on the components in combination with the pump head made of stainless steel with no alternating pressure loads to ensure low wear and extremely smooth running. The plungers move the conveyed medium with almost no pulsation and an efficiency of up to 95%.
Technical features
The valve block is not subjected to alternating stress and therefore not sensitive to cracking by low cycle fatigue. A minimum clearance volume (dead area) results in low pulsation and high volumetric efficiency.
- Invalve housing
- High-pressure labyrinth seal
- PTFE Bellows
- Zero Emission® design
- All high-pressure parts are encapsulated within the suction chamber
Reference project: passenger and car ferry
- The ferry is equipped with 4 powerful HAMPRO® 72 methanol injection pumps, which have an operating pressure of 600 bar and a flow rate of 50 l/min. The pumps have been in operation since 2015.
- The „Zero Emission®“ design completely separates the medium from the environment, so that the pumped medium cannot escape to the outside in any operating state.
- CO2 pumps for CO2 transfer and injection
- Liquid ammonia and carbonate pumps for fertilizer production
(Haber-Bosch-process)
- Boiler feed water pumps and wash water pumps
- Fuel injection pumps for liquid ammonia and methanol (ship engines)
