The Prelubrication Pump Relay is an electrical component that manages the operation of the pre-lubrication pump in engines. It energizes the pump to circulate lubricants through engine parts before the engine is started. The relay receives signals from the engine control unit or operator input, enabling controlled and timely operation of the pump. By ensuring proper lubrication at startup, the relay helps extend engine life and improve reliability.Attributes:• Controls electrical flow to initiate prelube function ahead of main startup.• Reduces surface contact wear by powering lubrication early in the cycle.• Enables timed operations using integrated or externally timed control signals.Applications: The Prelubrication Pump Relay is mounted within the electrical control panel or relay box, connecting the electrical system to the pre-lubrication pump, receiving control signals, and switching power to the pump motor accordingly.
