A pump gearbox is a specialized mechanical drive system used to connect a motor to a pump, adjusting speeds and torque for optimal fluid transfer. These systems are essential in high-pressure, viscous fluid, or industrial applications like oil, gas, and water treatment, often using external or internal interlocking gears. Common configurations include 2:1 or 1.5:1 ratios to reduce high-speed motor RPM to match pump requirements, protecting against overloading.
