Wanner™ Hydra-Cell® Pro seal-less pumps enable more environmental marine fuels and the use of seawater in on-board applications.

Alternative Marine Fuels

Environmental concern, reduction of SOx and NOx emissions, is driving large changes in the types of liquids used as fuels for marine engines. This is leading to the search for liquid fuels which will dramatically reduce or eliminate polluting emissions. Alternative fuels under serious consideration and growing use include, LNGs (Liquid Natural Gases), Methanol and Ammonia.

There are challenges in ping these liquids:

• All have very low viscosities and are non-lubricating
• Involve higher system pressures
• Are more volatile resulting in explosive risk assessment
• Some are more toxic than the tradition heavy fuel oils.

The Hydra-Cell® Pro pumps seal-less design, hydraulically balanced diaphragms delivering high pressure performance addresses all the points above, meeting the challenges of the Marine industry. ATEX certification from an independent notified body ensures that the Hydra-Cell pump is safe to use in classified explosive zones.

Reliability, easy minimal servicing, adaptability and zero leakage are all important attributes a pump should have for marine service. Hydra-Cell Pro seal-less simple design ensures compliance to all these attributes.

Hydra-Cell Pro industrial marine pumps are able to handle the low-sulfur diesel fuels required by new environmental regulations, that are thin and non-lubricating. Moreover their viscosity further reduces as they get hotter. Hydra-Cell Pro’s seal-less design is the optimum technology for handling these new fuels in marine industry pumping applications, and keeping them safely contained. Energy and installation costs are also saved as other pump technologies in the marine industry may require expensive fuel cooling units to keep the viscosity of the fuel high enough not to cause problems.

All dynamic seals leak a small amount. Hydra-Cell Pro's seal-less design keeps the ultra low-sulfur fuel safely contained. With no leakage, there is no need for equipment to monitor fuel leaks.

Emission control regulations also apply directly to the exhaust gases of marine engines. Urea, seawater and lime slurries are among the control chemicals reliably delivered to the exhaust by Hydra-Cell Pro pumps.
