High Viscosity Anti-Wear Hydraulic Oil DEPA.HY46 from China Suppliers & Factory - Ideal for High-Speed Hydraulic Systems
Advantages
- ✓ Very long service life.
- ✓ Excellent anti-scuffing property gives special protection even when high speed, high pressure and high temperature conditions are encountered.
- ✓ Excellent corrosion and rust prevention.
- ✓ Good demulsibility promotes quicker water separation. If water is an unavoidable contaminant, this advantage effectively retains lubrication.
- ✓ Anti-foam additive allows any entrained air to be released and burst quickly, ensuring enough lubrication between machine parts at any time.

Take Care
- 1 Small details to prevent you from spending money in vain.
- 2 Consult a lubrication expert, use lubricants of the appropriate specification, and try to minimize the types of oil used.
- 3 Replace the filter element at the same time as each oil change.
- 4 Keep the fuel tank sealed to prevent the entry of flying dust and moisture.
⚠️
For all kinds of different types, it is essential to use dedicated oil pumps. In particular, pure oil and water-based coolant must not be mixed with oil pumps. This may cause rust on metal parts in the equipment's lubrication system and increase wear. Moreover, the cutting fluid mixed with impurities may breed bacteria, thereby shortening its service life.
Frequently Asked Questions
Q
What grades are available for this hydraulic oil, and how do I choose the right one?
This hydraulic oil is available in three viscosity grades: hY32, hY46, and hY68. The right grade depends on your equipment's operating temperature range and the manufacturer's specification. hY32 suits lighter-duty or lower-temperature applications, while hY68 is better for high-load or high-temperature environments. Consulting a lubrication expert is recommended to match the correct grade to your system.
Q
How does the anti-scuffing property protect my equipment?
The anti-scuffing additive forms a protective film on metal surfaces, preventing direct metal-to-metal contact under high speed, high pressure, and high temperature conditions. This significantly reduces surface wear and extends the service life of hydraulic components such as pumps, valves, and cylinders.
Q
What should I do if water enters the hydraulic system?
This oil's good demulsibility allows water to separate quickly from the oil. While water contamination should be minimized by keeping the tank sealed, the demulsification property ensures that any unavoidable water is separated efficiently, preserving lubrication performance. Always check and drain water from the reservoir during routine maintenance.
Q
How often should I change the hydraulic oil and filter?
Oil change intervals depend on operating conditions and equipment manufacturer guidelines. As a best practice, always replace the filter element at the same time as each oil change. This prevents contaminated filter media from degrading the fresh oil and maintains system cleanliness.
Q
Can I mix this hydraulic oil with other oils or fluids?
No. Mixing this oil with other lubricants, water-based coolants, or cutting fluids is not recommended. Cross-contamination can cause rust on metal parts, increase wear, and allow bacteria to breed in the fluid — all of which shorten service life and damage equipment. Always use dedicated oil pumps for each fluid type.
Q
What is the flash point of this hydraulic oil, and why does it matter?
The flash point ranges from 215°C (hY32) to 250°C (hY68), indicating the minimum temperature at which the oil vapor can ignite. A higher flash point means greater fire safety in high-temperature operating environments. This makes the oil suitable for demanding industrial hydraulic systems where heat buildup is a concern.
