(Radolfzell/Germany) Allweiler AG, a member of Colfax Corporation, is already delivering fuel pumps that are adapted for use with new low-sulfur diesel oil. The company employs an analytical program that shows conversion options or suitable replacements for pumps that are already in service. National and international regulations now require low-sulfur fuels, especially in coastal areas and while ships are in port. However, not all existing pumps can handle the lower viscosity of these fuels without modification.

In order to comply with the regulations, pump users in the Marine segment must use diesel fuels with much lower viscosity than before. These new specifications have the potential to exceed the operational limits of existing fuel pumps. As a result, the safety and reliability of ship borne fuel systems may be fundamentally altered.

Fortunately, Allweiler AG offers special pumps designed for use with these new fuels. In addition, many previously installed Allweiler pumps can be retrofitted for use with the new viscosities. Allweiler technicians use 'Allweiler Fuel Oil Check' for each ship to determine whether the current pump is operating within its limitations. If the pump is no longer capable of handling the operating conditions, Allweiler can recommend a conversion kit or replacement pump. “Allweiler Fuel Oil Check” makes it easy to quickly and reliably determine whether fuel pumps are suitable for operation with low-viscosity, low-sulfur fuels and which alternative fuel pumps are available for each specific ship.

According to Arne Forslund, an Allweiler board member and Senior Vice President for Europe, Middle East, Africa, and Asia, 'The new or modified Marine pumps from Allweiler enable shipowners and shipyards to comply with all current and previously announced environmental regulations.'

The regulations are defined in the International Convention for the Prevention of Pollution From Ships (MARPOL 73/78), which defines global limits for nitrogen oxides and sulfur oxides, and in EU directive 2005/33/EC (effective January 2010), which restricts fuels to a sulfur content of no more than 0.1 percent by weight during lay days in European ports.
