Choosing a hydraulic gear pump means balancing flow, pressure, shaft specs, and port sizes against what your existing system can accept. Get those details right and installation is straightforward; get them wrong and you'll be modifying mounts or lines before the pump ever turns.
Dynamic Fluid Components GP-F20-08-P1-A Hydraulic Gear Pump
The Dynamic Fluid Components GP-F20-08-P1-A is a new gear pump from the GP-F20 series, priced at USD 191.62. It's a compact unit with a displacement of 0.48 in3/rev and a maximum pressure rating of 3,650 psi.
#### Quick verdict
If your system needs a compact gear pump that handles up to 3,650 psi, runs counter-clockwise, and accepts a 3/4-inch straight shaft, the GP-F20-08-P1-A deserves a close look. The specs are clearly spelled out, so you can match them against your application before committing.
#### Who it suits
This pump suits hydraulic systems that call for a SAE-12 inlet and SAE-10 outlet. The SAE A 2-bolt mounting flange is a standard configuration, and the pump provides a displacement of 0.48 in3/rev. It operates at a rated speed of 2,000 rpm and can handle up to 3,600 rpm.
#### What stands out
The GP-F20 series uses an aluminium center section with cast iron end plates, a construction often used in high-pressure gear pumps. The 3,650 psi maximum pressure is a key spec for a pump of this size. Side port measurements are 3.95 inches and rear port measurements are 4.40 inches, giving you port-routing flexibility. Weight is 11.0 lbs, and the overall dimensions are 4 × 4 × 4 inches, which helps when planning space.
#### Meaningful trade-offs
The main trade-off is the counter-clockwise rotation. If your application runs clockwise, this pump won't work without changing the drive arrangement. The 3/4-inch straight shaft also means your coupling must match exactly. While the pump is rated for 3,650 psi, the rated speed is 2,000 rpm, so confirm your continuous speed is within that range.
#### Bottom line
The Dynamic Fluid Components GP-F20-08-P1-A is a targeted choice for a specific set of parameters: SAE-12 inlet, SAE-10 outlet, 0.48 in3/rev displacement, 3/4-inch straight shaft, counter-clockwise rotation, and up to 3,650 psi. At $191.62, it's priced for a drop-in replacement or a new build with these exact specs. Verify rotation direction and shaft coupling before you order.
