Federal-Mogul Corporation has developed an electrical brushless diesel fuel pump for on- and off-highway engines with significantly improved durability. The technology suits 12V and 24V applications and is available for diesel engines typically used in the medium- and heavy-duty on-highway sector and in the construction, stationary, marine and agricultural sectors.
The brushless motor design utilizes electronic controls for high current switching to increase the reliability of the motor. Federal-Mogul says that the higher efficiency motors offer enhanced torque-speed performance, with support for higher pressures and flow capabilities.

A typical electric pump is more fuel-efficient than those driven directly by the engine; however, the carbon commutator and brushes found in conventional pumps are subject to wear, which is accelerated by high engine vibration and variations in diesel fuel.
Federal-Mogul says that its electrical brushless fuel pump addresses the shortcomings of a conventional fuel pump. With electronic commutation to drive the DC motor, the non-contact technology is more durable than a conventional pump even when mounted directly on the engine.

Durability field tests of Federal-Mogul’s electrical brushless pump showed that the product can last approximately 20 times longer than a conventional pump. The electrical brushless pump has undergone lab testing with various fuels, including SME B100 and RME B100. The pump’s efficient electrically-driven design also reduces the load placed on the engine when compared to conventional belt or gear driven pumps, thereby improving fuel economy and reducing emissions.
Federal-Mogul’s electrical brushless motor’s universal design also provides ease of installation in existing fuel pump packages to replace current brush-style motors. The design enables the product to enhance the life of an engine in service and reduce maintenance expenses.
Federal-Mogul is currently supplying its electrical brushless fuel pump to leading global diesel engine and diesel fuel filtration manufacturers. The company also is offering its electrical brushless fuel pumps through its aftermarket channels for on-highway diesel truck applications.

This could be one of many future e-fuel pump. More highly efficient e-ancillaries could be on the market within 5 years or so.
