Oilgear PFBA-2/2 Fixed Displacement Piston Pump is built to tackle hydraulic systems that handle extremely high pressure and deliver fluid with real precision, so you can be sure of reliable performance over the long haul. With a dead-set displacement of 4.5 cc/rev, this pump is all about consistency - providing a constant flow that's perfect for applications where accuracy and dependable hydraulic performance are a must.
It's part of Oilgears top-notch PFBA high-pressure pump family, and the PFBA-2/2 has got serious credentials - it can deliver up to 1000 bar of pressure on the continuous rating. That means this pump can handle its stuff in some really tough industrial environments. And it's perfect for applications that need to handle a lot of force - think forging presses, intensifier systems, heavy machinery and all sorts of high-pressure equipment.
The PFBA-2/2 has a stationary piston body design, which is a real plus because it eliminates all the centrifugal pressure that can wear out a pump's components - so you can expect to get a lot more life out of this pump. Plus, the hardened surfaces and robust design mean it can handle contaminants in the fluid a lot better than some of the older pump designs out there. And its compatible with low-viscosity and even water-based hydraulic fluids too, so it can handle any special hydraulic fluids your system might need.
Performance-wise, the PFBA-2/2 has got it where it counts - it delivers a steady flow at a range of operating speeds, and at 1800 RPM under rated pressure its churning out around 1.96 gpm (that's 7.4 l/min if you're using metric). That's what you need in a system where precision, pressure consistency and fast response times are key.
The PFBA-2/2 pump is also super compact - easy to install in tight spaces without taking up too much room. Plus, with its fixed displacement design, you get a system that's super easy to control and much more reliable, especially when you need the flow to stay constant no matter how fast or slow the speed or load is changing.
