The GRACO 560157 is a feed adjusting nut, typically constructed from durable metal, designed to regulate the pumping rate in GRACO lubrication equipment. Its primary function is to allow manual adjustment of the fluid delivery rate during the pump suction stroke, ensuring precise lubrication control. Key Features: Hex Nut Overall Height: 1.5 in (38.1 mm) Compatible with GRACO lubrication systems, including models such as HP50 and HP60 High Pressure Lubricators Manual adjustment for precise flow control Durable construction for reliable operation Easy to install and maintain Applications:Used in GRACO lubrication systems to regulate the delivery of lubricant to machinery, suitable for industrial, mining, and agricultural applications. Installation Notes: Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of lubrication equipment. Adjust the feed adjusting nut by hand during the pump suction stroke for accurate flow rate setting Turn clockwise to increase pumping rate, counter-clockwise to decrease Allow sufficient time for the system to stabilize after rate changes for accurate indication Regularly inspect for wear or damage Ensure proper seating and adjustment for consistent performance
