- How Gear Pumps Work:
- A gear pump operates by using two interlocking gears that rotate to create a cavity. As the gears turn, fluid is drawn into the cavity and pushed out to the system, creating pressure. This continuous cycle of fluid movement is vital for maintaining hydraulic pressure and ensuring the machine’s proper operation.
