Lubrication systems for well service pump packing inject grease or liquid lubricants into stuffing boxes, reducing friction and cooling packing elements. Proper lubrication extends packing life significantly by reducing heat generation and providing boundary lubrication preventing direct material contact between plungers and packing surfaces during reciprocation. https://globalsealstech.com/product-category/oil-gas-seals/oil-free-lubricated-pump-seals/
