Product Description
KATMOTO HYDRO HM 100 is a premium anti-wear hydraulic oil meeting DIN 51524-2 HLP / ISO HM for construction, mining and industrial hydraulic systems. Its zinc-based anti-wear additive system provides excellent pump and valve protection, with strong oxidation and thermal stability, rapid water separation, good air release and reliable rust and corrosion protection for dependable, long-life hydraulic performance.
Key Performance Features
| Excellent anti-wear protection
protects vane, gear and piston pumps under high pressure and load. |
Oxidation & thermal stability
resists oil thickening, sludge and varnish for long oil life. |
| Rapid water separation
fast demulsibility keeps the hydraulic system dry and protected. |
Rust & corrosion protection
protects hydraulic components against rust and corrosion. |
| Good air release & low foam
minimises foaming and entrained air for stable hydraulic response. |
Wide equipment suitability
suitable for excavators, loaders, cranes and industrial hydraulics. |
Applications & Performance Level
| Applications | Hydraulic systems of excavators, wheel loaders, cranes and industrial equipment, and general anti-wear hydraulic applications where an ISO VG 100 DIN 51524-2 HLP / ISO HM oil is specified. |
