An Auxiliary Water Pump fits into the keyway of the water pump shaft and the impeller, creating a positive connection that transmits torque from the shaft to the impeller. This synchronized rotation allows the impeller to effectively draw in and propel water, facilitating the pump's operation.Attributes:• Maintains precise alignment between the shaft and impeller for smooth operation• Manufactured to precise specifications and is built for durability and reliabilityApplications:An Auxiliary Water Pump efficiently transmits torque from the water pump shaft to the impeller, enabling the pump to effectively move water. It provides a precise and secure fit within the keyway, minimizing the risk of slippage or misalignment.
