Power to move your material with maximum speed, ease, and precision
A Logical Layout
All major hydraulic components are strategically located close together. This positioning leads to reduced friction loss and pressure drops, and the result is more hydraulic horsepower for the heavy-lifting, ground-breaking work you need to get done.A Forceful, Responsive Design
The 325F features a negative flow control hydraulic system. In layman’s terms, negative flow control decreases pump flow when oil pressure increases and vice versa. The net result is the pump and valve operate in harmony with less energy and less wear and tear. What’s really new with the 325F is the hydraulic valve’s electronic control. Integrated with the electronic engine, the hydraulic power with electronic control is smoother and more responsive than traditional hydraulic control. It also contributes to less energy consumption and less wear and tear, and both of those translate into lower owning and operating costs for you.Valves For Added Efficiency
The 325F is built with a back-to-back main control valve, and the benefit to you is reduced pressure loss and fuel consumption due to the shorter distance oil has to travel. The machine also features special boom and stick valves that recirculate oil flow in the cylinders during work instead of going all the way back to the tank. The valves contribute to energy savings, but their primary benefit is allowing more oil to flow to other functions so you can experience faster cycle times and more production.Tool Control For Enhanced Performance
Tool control is a distinct Cat excavator advantage that adds incredible convenience and enhanced performance to your everyday work. The electronic system stores flows and pressures for up to 20 work tools right in the cab monitor, eliminating the need to calibrate tools every time you make a change out front. It works with both one- and two-way-flow tools, and it can be outfitted with a third pump and medium-pressure circuit so you can use tools like shears, grapples, and tilt buckets. Standard high-pressure circuits make the tools open and close; medium-pressure circuits enable them to rotate. Adding an optional quick coupler circuit makes tool changes even faster for maximum productivity.Other Cat Exclusive Hydraulics Advantages
Main Pump – The purpose of the main pump is to convert the engine’s mechanical energy into hydraulic energy, and the 325F’s pump does that job very well. Its displacement (amount of fluid pumped per revolution) is high so the machine can deliver ground-breaking performance at lower engine speeds. That translates into less wear and tear on the hydraulic system and more fuel savings for you.
Capsule Filter – The capsule filter is designed to take out impurities and help you avoid system contamination and accidental spilling. The self-contained, maintenance-friendly filter is easy to remove with a simple wrench. It can take out impurities as small as beta 10 – particles so tiny you cannot see them with the eye. A sensor lets you know if there is a clog or if pressure exceeds a certain level so you can take action.
Drain Filter – A drain filter is one extra level of contamination prevention. Located in the pump compartment behind the pilot filter, the drain filter purifies the case drain from the main pumps, swing motor, and travel motors – all to enhance the life of the pumps and motors and uptime for you.
Powerful and fuel efficient to meet your expectations
Every Tier 4 Final ACERT™ engine is equipped with a combination of proven electronic, fuel, air, and aftertreatment components. Applying these time-tested technologies lets us meet your high expectations for productivity, fuel efficiency, reliability, and service life.
Less Fuel, More Power
Following are the results you can expect:
- Improved fuel efficiency over the Tier 3 321D

While the 325F consumes up to 22% less fuel than the Tier 3 321D, the engine actually delivers more horsepower. How’s that possible? Simple. Advanced engine technology and system control. Isochronous control, for example, permits the engine to run at a constant lower speed but at an optimum point in the power curve for maximum efficiency. Automatic engine speed control also contributes by lowering rpm when the machine isn’t calling for it. Automatic engine idle shutdown turns the engine off when it’s been idling for more than a specified amount of time, which you can easily set through the monitor. Plus you have a choice of three power modes – high power, standard power, and eco mode. Simply change between modes through the switch panel to meet the work needs in front of you. Collectively, all of these benefits add up to reduced fuel consumption, reduced repair and maintenance costs, and increased engine life for you.Biodiesel Not A Problem
The C4.4 ACERT engine can run on up to B20 biodiesel that meets ASTM 6751 standards – all to give you more potential fuel-saving flexibility.
Sized right for tight quarters work
Work With Confidence
The 325F L’s compact radius design makes it ideal for working confidently in space-restricted areas like road jobs with lane closures and next to buildings or other structures you’d like to keep out of harm’s way. With a front swing radius of 2.34 m (7'8") and a tail swing radius of 1.72 m (5'8"), the machine can dig, swing, and dump within a working space of 4.06 m (13'4"). When rotated 90 degrees and working over the side, just 135 mm (5") of counterweight extends beyond the track width, which allows trucks and jersey barriers to be positioned closer to the machine.Work With Power
Unlike a standard radius machine, the 325F’s boom is positioned toward the center of the machine. Not only does this help reduce the front swing radius, but it also supports more lift capacity over the front due to greater stability.Work With Comfort
The machine features a full-size roll-over protective structure (ROPS) cab. With low sound levels, high visibility, convenient access to switches and controls, and a fully adjustable seat, you will find it comfortable to work in all day long.
