Fuel Metering Pumps

Simple systems are run at fixed speed with electric motor drive and in these systems the pump delivery is directly proportional to swash plate angle irrespective of discharge pressure. It is possible to drive the pump mechanically from the auxiliary gearbox of a gas turbine whereby a more sophisticated controller can be used to compensate the delivery for pump speed changes. This type of system is very cost effective for black start applications. Because the metering pump only delivers the fuel demanded by the turbine to meet the load, no recycling of fuel is required so that the pump consumes a minimum amount of power and thus imparts no heat energy to the fuel supply. The pump therefore runs cool so maintaining the lubricity of the fuel which extends the wear life of the pump and fuel system.

HEINZMANN actuators used in metering pump systems are independently certified for application in hazardous areas to ATEX and CSA standards permitting their use in almost all turbine applications
