The Standard Industrial Grade

ISO VG 46 is the most commonly specified grade for general industrial hydraulic power units, mobile construction equipment and manufacturing plant hydraulics operating at normal South African ambient temperatures — one product covering the widest range of equipment.

Anti-Wear Pump Protection

Anti-wear (HM) additive system protects gear, vane and piston pumps from wear under the high contact loads and pressures typical of industrial hydraulic systems — reducing pump wear rates and extending component service life versus non-anti-wear HH grade hydraulic oils.

Good Oxidation Stability

Good resistance to oxidative degradation helps prevent sludge and deposit formation in the hydraulic reservoir and system — maintaining system cleanliness and consistent hydraulic performance throughout the oil's service life.

Rust & Corrosion Protection

Good rust and corrosion protection for hydraulic system components — protecting cylinder bores, pump internals, valve surfaces and reservoir walls from corrosion in the presence of water contamination in marine, offshore and mining environments.

Foam Control & Air Release

Good foam control and air release properties maintain consistent fluid compressibility — ensuring reliable hydraulic system response and preventing the spongy, erratic operation caused by air entrainment in high-cycle industrial hydraulic systems.

Demulsibility

Good water separation (demulsibility) — the oil separates rapidly from water contamination rather than forming emulsions. Emulsion time to 3ml at 54°C: 15 minutes. Maintains oil quality and reduces the accelerated wear and corrosion caused by water-in-oil emulsions in hydraulic systems.

General Industrial Hydraulic Power Units

The standard specification for the majority of industrial hydraulic power units in South Africa — manufacturing plant, processing equipment, presses, machine tools and any industrial hydraulic system where the OEM nameplate specifies ISO VG 46 HM hydraulic oil.

Mobile Construction & Mining Equipment

Excavators, loaders, ADTs and general construction and mining machinery specifying ISO VG 46 anti-wear hydraulic oil — the most widely specified grade for mobile hydraulic equipment operating at typical South African ambient temperatures.

Marine & Offshore Hydraulics

Marine hydraulic systems specifying ISO VG 46 — deck machinery, steering gear, hatch cover hydraulics and offshore platform equipment where Denison HF-0/1/2 approval is required.

Precision Manufacturing Hydraulics

Fives Cincinnati P-70 approved — precision manufacturing machinery, CNC equipment and machine tool hydraulics specifying Fives Cincinnati P-70 at ISO VG 46.

Agricultural Equipment

Tractor hydraulic systems, implement lift circuits and agricultural machinery hydraulics specifying ISO VG 46 anti-wear hydraulic oil — the most widely specified grade for agricultural equipment in the Western Cape and Northern Cape.

Gear, Vane & Piston Pump Systems

All common hydraulic pump types — gear pumps, vane pumps and piston pumps — in industrial and mobile hydraulic systems specifying ISO VG 46 anti-wear (HM) hydraulic oil.
