What are the two types of hydraulic pumps?

Hydraulic pumps can be categorized into two primary types based on their design and operation. Gear pumps and piston pumps are both widely used in hydraulic systems.

Gear pumps utilize interlocking gears to move the hydraulic fluid. As the gears rotate, the fluid is trapped in the spaces between the teeth and is carried from the inlet to the outlet, creating a continuous flow. This type of pump is known for its simplicity, reliability, and ability to deliver a consistent flow rate, making it suitable for many hydraulic applications.

Piston pumps, on the other hand, rely on the back-and-forth motion of pistons within cylinders to create hydraulic pressure. This type of pump can produce higher pressures than gear pumps and is often used in applications requiring precise control over flow and pressure. Piston pumps are more complex but offer versatility and efficiency in a wider range of hydraulic systems.

The combination of these two types, gear pumps and piston pumps, covers a variety of hydraulic applications and needs, such as different flow rates and pressure requirements, making them the two main categories of hydraulic pumps.
