Heavy, medium, and light plunger grease for hydraulic pumps

Abstract

A lubrication product used in the packings and plungers of hydraulic pumps used in fracking and other oilfield applications. The composition including: 1) diluent oil, comprising of naphthenic, paraffinic, or synthetic origin ranging from 60 SUS to 3000 SUS at 100° F.; 2) olefin co-polymers, either high propylene or high ethylene, or combinations thereof; 3) polybutene, ranging in molecular weights from 100-6000 4) high molecular weight poly-ISO-Butylene, ranging from 500,000 to 3,000,000; 5) PIBSA dispersant; 6) performance additives, containing anti-wear and extreme pressure properties. Most preferable is a sulfur/phosphorus gear oil package.
