Keep your high-pressure misting pump running at peak performance with the only crankcase oil engineered specifically for Cat Pump misting systems. This premium-grade, petroleum-based ISO 68 hydraulic oil is a custom blend formulated exclusively for Cat Pump applications — not a generic hydraulic oil repurposed for misting use. The advanced additive package is designed to protect against the four primary causes of pump crankcase failure: wear, oxidation, rust, and corrosion — all of which accelerate rapidly when the wrong oil is used in a high-pressure, high-cycle misting environment.

Annual oil changes are one of the most important maintenance steps for any Cat Pump-based misting system. Fresh oil maintains the protective film between moving crankcase components, neutralizes acids that accumulate during normal operation, and prevents moisture from corroding internal surfaces during seasonal downtime. Using the manufacturer's own custom blend removes any guesswork about viscosity matching and additive compatibility. One 21 oz. bottle — model 57025 — is the standard annual oil change quantity for most Cat Pump misting pump models. MSDS sheet available from Cat Pumps directly.
