Ensure consistent, air-free lubrication and minimize product waste with the Piusi Follower Grease Plate. Specifically engineered for medium-sized containers, this follower plate is an essential component for any professional pneumatic grease system. By exerting constant downward pressure on the lubricant, it prevents the common “tunneling” effect where the pump suction tube draws in air instead of grease, leading to pump cavitation and inconsistent flow.

The F20597000 features a 420 mm (16.5″) diameter, precision-sized for standard 120 lb (50–60 kg) grease kegs.

Key Features & Benefits

• Eliminates Air Pockets: As your pneumatic pump draws grease, the follower plate uses atmospheric pressure and the pump’s vacuum to stay seated firmly against the grease surface. This ensures a continuous “prime,” preventing the pump from sputtering or dry-running.
• Reduces Grease Waste: The outer edge is equipped with a high-durability, flexible rubber membrane that acts as a squeegee. As the plate descends, it wipes the inner walls of the keg clean, allowing you to extract nearly every ounce of high-value lubricant.
• Contamination Shield: By providing a physical barrier over the exposed grease, the plate protects your supply from shop dust, moisture, and metal shavings. This is critical for preventing abrasive particulates from reaching sensitive bearings or damaging high-pressure pump seals.
• Heavy-Duty Construction: Built with a reinforced steel core, providing the necessary weight to handle high-viscosity greases (up to NLGI #3) even in colder workshop temperatures.
• Precision Center Grommet: Features a 30 mm (approx. 1.2″) center opening with a tight-fitting rubber seal designed to slide smoothly over standard pump suction tubes while maintaining an airtight vacuum.
• Corrosion-Resistant Finish: Treated with an industrial-grade coating to resist the chemical properties of extreme-pressure (EP) greases and the humidity of a busy service bay.

Technical Specifications

Without a Piusi F20597000, high-viscosity grease cannot level itself out as the pump draws from the center. This creates a “cone” of wasted grease stuck to the sides of the keg and allows the pump to suck air, causing “hammering” and internal wear on the pump motor. Using this follower plate is a simple, cost-effective way to extend the life of your equipment and keep your shop floor clean.
