High Performance DEPA.HY46 Hydraulic Oil - China Suppliers and Factory for Extreme Conditions
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 extreme conditions such as high speed, high pressure, and elevated temperatures. This significantly reduces surface wear and extends the service life of hydraulic components.
Q
Why is good demulsibility important in a hydraulic oil?
Good demulsibility means the oil can quickly separate from water contamination rather than forming a stable emulsion. This keeps the oil's lubricating properties intact even when water enters the system, protecting components from corrosion and maintaining consistent hydraulic performance.
Q
How often should I change the hydraulic oil and filter?
Always replace the filter element at the same time as each oil change. The oil change interval depends on your equipment's operating conditions and the manufacturer's guidelines. Regular oil analysis is a good practice to determine the optimal change interval and catch contamination issues early.
Q
Can I mix this hydraulic oil with other oils or water-based fluids?
No. Mixing this oil with other lubricants or water-based coolants — especially through shared oil pumps — is strongly discouraged. Cross-contamination can cause rust on metal parts, increase wear, and allow bacteria to grow in the fluid, all of which shorten service life and damage equipment. Always use dedicated oil pumps for each fluid type.
Q
What precautions should I take when storing hydraulic oil?
Keep the fuel tank and storage containers tightly sealed at all times to prevent dust, moisture, and airborne contaminants from entering. Store in a cool, dry location away from direct sunlight and heat sources. Contamination during storage is one of the most common causes of premature oil degradation and equipment wear.
