Hydraulic, gear, turbine, compressor and marine oils, greases and metalworking fluids for plants and heavy equipment.
Light-viscosity grade for precision machine tools and cold-start conditions.
The most widely used hydraulic grade in Iranian industry and plant equipment.
Heavier grade for hot climates, worn pumps and heavy presses.
Stays in grade from frosty mornings to scorching afternoons on outdoor equipment.
Hydraulic systems turn oil into force. Diaco hydraulic oils keep pumps, valves and cylinders responsive, clean and protected — shift after shift.
Zinc-based anti-wear chemistry protects vane, piston and gear pumps, while excellent air release and demulsibility keep systems free of foam and water.
Our high viscosity-index HV grades stay stable across wide temperature swings, ideal for mobile equipment working outdoors in Iran's varied climates.
Long oxidation life for steam and gas turbines in power and petrochemical plants.
Resists carbon deposits on valves of reciprocating air compressors.
For enclosed industrial gearboxes in cement, steel and conveyor drives.
Heavier gear oil for slow, heavily loaded mill and crusher gearboxes.
For paper machine and rolling mill circulating systems with high water exposure.
High dielectric strength insulating oil for power and distribution transformers.
Uptime is everything in industry. Our turbine, compressor, gear and transformer oils are formulated to run longer between changes and protect critical assets.
Industrial gear oils with sulphur-phosphorus EP chemistry protect enclosed gearboxes in cement mills, conveyors and steel rolling. Turbine and circulating oils offer long oxidation life and excellent water separation.
Compressor oils resist carbon formation at high discharge temperatures, and our inhibited transformer oil provides high dielectric strength for power distribution equipment.
Multipurpose grease for wheel bearings, chassis points and electric motors.
High-temperature grease for disc-brake hubs, kilns and steel mill bearings.
Excellent water resistance for agricultural, marine and washdown equipment.
Moly-fortified grease for shock-loaded pins, bushings and CV joints.
Where oil would run off, grease stays put. Diaco greases seal out dirt and water and keep bearings, pins and bushings turning under heavy loads.
Our range covers multipurpose lithium EP greases for everyday bearings, high-temperature lithium-complex greases for wheel hubs and steel mills, water-resistant calcium greases and molybdenum-fortified greases for shock-loaded pins.
All greases are tested for mechanical stability, water washout and corrosion protection to keep re-greasing intervals predictable.
For auxiliary engines and main engines burning distillate or low-sulphur fuel.
For medium-speed engines running on heavy fuel oil.
Cylinder oil for two-stroke crosshead engines on high-sulphur fuel.
Forms a stable emulsion with ingressed seawater to keep stern bearings protected.
From Persian Gulf ferries to ocean-going tankers, Diaco marine lubricants are matched to the fuel, engine and duty of each vessel.
Trunk-piston engine oils (TPEO) with the right base number neutralise acids from high-sulphur fuels, while our cylinder oils protect liners in two-stroke crosshead engines.
Deliveries in drums and IBCs to southern and northern ports are arranged in advance.
Stable, low-foam emulsion for CNC turning, milling and drilling.
Maximum lubricity for threading, broaching and gear hobbing.
Prevents stick-slip and keeps slideways accurate on machine tools.
Temporary protection for finished parts in storage and export.
Better finishes, longer tool life and cleaner workshops. Diaco metalworking fluids cool, lubricate and protect in machining and forming.
Our soluble cutting oil forms a stable milky emulsion for turning, milling and drilling, with biostability that resists bad odours. Neat cutting oils deliver maximum lubricity for threading, broaching and gear cutting.
Slideway oils prevent stick-slip on machine tool guides, and our rust preventives protect finished parts in storage and transport.
