Gas Fuel Pumps

Pump Operation

Safety & Reliability

Fuel pump control is directly related to the engine load. As the pump should deliver the right pressure/flow over the entire engine load range it will periodically operate at duty points where pump and motor have a low efficiency. If the electric motor is installed inside the fuel tank in some situations a low efficiency duty point induces up to 70% of electric energy losses, heating-up the LNG and increasing Boil Off Gas and the tank pressure. The Wärtsilä Svanehøj EFP has the electric motor located outside the fuel tank which eliminates that source of excess heat and pressure.

5 year service interval

The Wärtsilä Svanehøj EFP is based on well proven technology used on gas carriers for decades. We have designed a hermetically sealed pump without any sophisticated bearings or exotic materials, using standard ball bearings that ensure a long service lifetime.Service intervals are 25,000 operating hours, or every 5 years.
