A grease pump is a mechanical device used to dispense lubricating grease in various machinery and equipment. It helps ensure smooth operation by reducing friction between moving parts, which can prevent wear and tear. Grease pumps are commonly used in automotive, industrial, and agricultural applications. These pumps can be manual or powered, with some models designed for specific tasks, such as grease guns for handheld use. They often feature adjustable flow rates to control the amount of grease dispensed, making them versatile tools for maintenance and repair. Proper use of grease pumps can extend the lifespan of machinery and improve efficiency.
