If a pump's gears are partially frozen, it could lead to which effect?

When gears in a pump are partially frozen, it creates additional friction and resistance within the system. This resistance requires more energy from the motor driving the pump, leading to an increase in amperage. As the gears struggle to turn, the motor must work harder to overcome the added load, which is reflected by a rise in current drawn by the motor.

Increased amperage is a critical indicator of motor performance. It signals that the system is not operating efficiently and could potentially lead to overheating or further mechanical issues if not addressed. Understanding this relationship between the mechanical aspects of the pump and electrical consumption is vital for troubleshooting and maintaining optimal performance in heating systems.
