The Drive Gear transmits rotary motion from the power source to the pump's internal components. As the drive gear rotates, it engages with the pump's other gears, causing them to rotate well. This rotational motion creates a fluid-moving action within the pump.Attributes:• Ensure smooth engagement and accurate power transmission.• Withstand high mechanical stresses and pressures.• Transmits power to the pump's driven gear.• External involute spline 14-Teeth.• Internal involute spline 17-Teeth.Applications: The Drive Gear helps to engage with the pump's impeller gear, converting rotational energy into fluid displacement within the gear pump.
