Greasing Machine Manual

Greasing Machine Manual

1. High-Pressure Pumping Mechanisms

• Pressure Capacity: Heavy-duty manual lever systems typically generate 5,000 to 10,000 PSI . This immense pressure is vital for clearing out clogged, dried, or blocked Zerk fittings.
• Discharge Volume Control:

oLever-Type: Offers maximum mechanical leverage, dispensing approximately 1.28 grams of grease per stroke.

oPistol-Grip Type: Designed for one-handed operation in tighter spaces, providing about 0.86 grams per stroke.

oVariable Stroke Feature: Advanced models offer a variable stroke, allowing for short, tight strokes in confined areas or long, powerful strokes in wide-open settings.

2. Reservoir & Body Construction

• Robust Barrels/Tanks: The main body is constructed of heavy-gauge steel, aluminum, or—in stationary multi-point workshop pumps— transparent acrylic reservoirs to allow immediate visual checking of the grease level.
• Follower Plate Assembly: An internal spring-loaded follower plate ensures continuous positive suction by neatly wiping the barrel walls and pressing the grease toward the pump head as the reservoir empties.
• Tell-Tale Indicator Rod: A rod attached to the follower plate protrudes through the bottom of the tool, giving the operator a physical reference of how much grease is left.
• Versatile Loading Options: Standard manual units support three filling methods: 3-ounce/14-ounce cartridges, suction loading directly from a tub, or bulk filling via a dedicated grease filler pump port.

3. Discharge Controls & Fitting Components

• One-Way Check Valve (Non-Return Valve): Located inside the pump head, this spring-and-ball mechanism prevents grease from suffering backflow when high-resistance joints are pumped.
• Air Bleeder/Purge Valve: A button or screw on the head cap used to vent trapped air pockets after reloading, ensuring quick priming and a consistent flow of grease.
• Dual Line/Progressive Distribution Compatibility: Bench or wall-mounted manual pumps can be linked directly to progressive distributor blocks , allowing a single pump to accurately feed grease across up to 20 to 50 individual lubrication points simultaneously.
• Flexible and Rigid Extensions: Equipped with high-pressure reinforced hoses for hard-to-reach, angled locations, or rigid steel tubes for open, straight-access fittings.
