Choosing the Dynamic Fluid Components GP-F20-12-P-C Hydraulic Gear Pump: Key Specs and Trade-Offs

Need a clockwise hydraulic gear pump with 0.73 displacement and 3650 psi max pressure? The GP-F20-12-P-C pairs a compact SAE A mount with SAE-12 inlet and SAE-10 outlet ports.

Last updated Aug 17, 2026

Choosing a hydraulic gear pump isn't a one-size-fits-all decision. It comes down to matching rotation, mounting flange, shaft size, and port fittings. The Dynamic Fluid Components GP-F20-12-P-C is a gear pump with specific answers to those requirements: clockwise rotation, a 2-bolt SAE A mount with a 3.25-inch pilot, a 5/8-inch straight shaft, SAE-12 inlet and SAE-10 outlet ports, and a 0.73 displacement.

Quick Verdict

If your hydraulic circuit calls for clockwise rotation, a 2-bolt SAE A mounting flange, and SAE-12 in / SAE-10 out connections, this pump is a direct match. Its 3650 psi maximum pressure and 2000 rpm rated speed fit moderate-duty hydraulic systems. The listed price is $191.62.

Who It Suits

This pump is suited for a system that needs a compact, 11-pound gear pump in a 6×6×6-inch package. Because it is designed for clockwise rotation, it fits applications that were built around that direction. The side ported and rear ported measurements-4.25 inches and 4.70 inches-help show where the port connections sit when you're positioning the pump.

One strong reason to choose this pump is that it's a new unit with a clearly defined spec set: 0.73 displacement, 3650 psi max pressure, and 2000 rpm rated speed. It's also made in the United States. The main limitation is the clockwise rotation; if your application needs counterclockwise operation, this pump won't work.

What Stands Out

The GP-F20-12-P-C uses a gear pump design with a 5/8-inch straight drive shaft and a 2-bolt SAE A mounting flange with a 3.25-inch pilot. The SAE-12 inlet and SAE-10 outlet port sizes match many mid-size hydraulic lines, and the 3650 psi maximum pressure gives a defined operating ceiling. Weighing 11 pounds and measuring 6×6×6 inches, it's compact enough for tight spaces.

Meaningful Trade-Offs

The biggest trade-off is rotation direction: this pump is clockwise. If your existing system was built for counterclockwise, this isn't the pump for that setup. The pressure rating is specific-3650 psi max-so it shouldn't be pushed beyond that. Speed-wise, the rated speed is 2000 rpm, and the maximum is 3600 rpm; the rated speed is the number to design around.

Bottom Line

The Dynamic Fluid Components GP-F20-12-P-C is a no-nonsense hydraulic gear pump for a specific clockwise, SAE A-mount, SAE-12-in/SAE-10-out setup. At $191.62, you're paying for clearly listed specs and a part number that's easy to match. If the rotation direction and port sizes align with your system, this pump is a straightforward choice.
