Frequently Asked Questions
❓
What viscosity grade should I choose — hY32, hY46, or hY68?
The choice depends on your operating conditions. hY32 is suitable for lighter loads and lower operating temperatures, hY46 is the most widely used general-purpose grade, and hY68 is recommended for heavy-duty applications with higher operating temperatures. Consult your equipment manufacturer's specifications for the recommended viscosity grade.
❓
How does the anti-scuffing property protect equipment under extreme conditions?
The anti-scuffing additive package forms a protective boundary film on metal surfaces, preventing direct metal-to-metal contact under high speed, high pressure, and high temperature conditions. This significantly reduces wear, extends component life, and maintains reliable performance even in demanding industrial environments.
❓
What does the demulsibility advantage mean for my hydraulic system?
Good demulsibility means the oil quickly and cleanly separates from water contamination. In hydraulic systems where water ingress is unavoidable, rapid water separation prevents emulsion formation, protecting components from corrosion and ensuring consistent lubrication performance throughout the system's service life.
❓
Why is the flash point important, and how does it compare across grades?
The flash point indicates the minimum temperature at which the oil vapor can ignite, making it a key safety parameter. hY32 has a flash point of 215°C, hY46 at 240°C, and hY68 at 250°C. Higher viscosity grades offer higher flash points, providing a greater safety margin in high-temperature operating environments.
❓
Can Depa provide customized hydraulic oil solutions for specific industries?
Yes. Depa specializes in providing customized lubrication solutions for a wide range of industries including military, aviation, medical, semiconductor, automotive, electronics, papermaking, and general machinery. Their R&D team works closely with customers to develop products that meet specific performance, environmental, and regulatory requirements.
❓
How does the anti-foam additive benefit hydraulic system performance?
Foam in hydraulic oil can cause cavitation, erratic system response, and insufficient lubrication at critical contact points. The anti-foam additive destabilizes air bubbles quickly, allowing entrained air to escape rapidly. This ensures consistent oil film thickness, stable system pressure, and reliable lubrication between all moving machine parts at all times.
