Caterpillar 325F Compact Radius Excavator Sees Boosts in Fuel Efficiency

The Caterpillar 325F is a compact radius excavator built with a Tier 4-Final Cat C4.4 ACERT engine paired with a responsive hydraulic system.

Compared with its Cat 321D Tier 3 predecessor, the 325F can run on biodiesel up to B20. Based on engineering validation, it will consume up to 22 percent less diesel fuel than its predecessor, with no loss of swing torque and bucket and stick forces, Cat says. With a maximum lifting capacity of 27,000 pounds at 15 feet over the front at ground level, the 325F exceeds its predecessor model’s capacity by 8 percent.

The 325F features electronic, fuel, air and aftertreatment components such as a maintenance-free DPF, and it has isochronous control that automatically manages pump and engine speed for improved fuel efficiency. Boom and stick recirculation valves reduce fuel consumption and speed up cycle times, and a choice of three power modes—high power, standard, and eco—help operators manage fuel consumption. A variable-speed fan for less energy consumption and noise, high-ambient cooling capability to work in extreme heat, and altitude capability up to 9,840 feet with no engine de-rating round out the machine’s high-performance attributes.
