Application Details
The 2643B319 high-pressure rotary distributor pump is engineered specifically for electronically governed Perkins 1104D-E44T and 1104D-E44TA engines (4.4 L, 4-cylinder). These engines power Massey Ferguson 7720 and 7722 S Dyna-VT tractors, Landini Rex 5-110/120/130 T-V ROW models, JCB 437S wheeled loaders and 540-170 Hi-Viz telehandlers, as well as FG Wilson P44-6 and Pramac GSW150P sound-attenuated generator sets. These engines deliver 110-130 kW at 2,200 r/min while meeting EU Stage IIIA/EPA Tier 3 emission limits. The pump ensures precise fuel metering for rapid torque rise, smoke-free acceleration, and reliable cold-starting in heavy-duty agricultural, construction, and standby-power applications.
