The High-Pressure Challenge: Why Your KEDA Hydraulic Press Needs the Right Industrial Hydraulic Oil
In the world of industrial ceramics and metal forming, the KEDA KDR400 hydraulic press is a powerhouse. Operating at pressures up to 30 MPa (300 bar), it demands incredible precision to transform dry powder into perfectly formed products.
But there is a silent partner in this process that often gets overlooked until it is too late: the hydraulic oil.
At Lukeron Lubricants, we’ve analysed the unique stress profiles of isostatic presses used in ceramic tile manufacturing across India — particularly in high-ambient-temperature states like Gujarat. Here is why selecting the correct industrial hydraulic fluid is the difference between a smooth-running factory and costly, unexpected downtime.
01Â The Battle Against Hydraulic Oil Shear Breakdown
The KDR400 operates under extreme force. When hydraulic fluid is forced through narrow servo valves at 300+ bar, the molecular chains in low-quality oils literally break apart — a process called viscosity shear degradation. This causes the oil to thin out and lose its protective film, leading to direct metal-on-metal contact inside your expensive KEDA hydraulic pumps and cylinders.
Standard mineral HLP oils fail this test quickly in high-cycle ceramic press applications.

Our formulations use shear-stable polymer additives that maintain viscosity under sustained 300 bar operating pressure — extending hydraulic pump life and reducing unplanned maintenance. |
02Â Managing Heat: High Viscosity Index Oil for Indian Shop Floors
Industrial plants in Gujarat, Rajasthan, and Maharashtra often operate in ambient temperatures exceeding 40°C. Hydraulic systems generate additional internal heat, and for every 10°C rise above the limit, the service life of a standard mineral oil is effectively halved.
This is why High Viscosity Index (HVI) hydraulic oil is essential for Indian industrial environments.
A low VI oil will become dangerously thin when hot — and too thick for efficient cold-start operation in winter mornings.
| THE LUKERON EDGE
Lukeron recommends HVI hydraulic fluids (VI 140+) for ceramic press applications in Indian climates. These oils protect seals and cylinders across all operating temperatures, reducing wear and extending change intervals. |
03Â Dust & Contamination Control in Ceramic Manufacturing
Ceramic tile production is a high-contamination environment. Even with best-in-class sealing, microscopic abrasive ceramic dust particles enter hydraulic reservoirs. Standard oils without adequate dispersant chemistry allow this contamination to form sludge that blocks sensitive servo valves — causing your press to become sluggish, inaccurate, or completely unresponsive.
A contaminated hydraulic system in a tile or sanitaryware plant can halt an entire production line — at a cost far exceeding the price of premium-quality oil.
| THE LUKERON EDGE
Lukeron’s premium hydraulic range includes advanced detergent-dispersant additive packages that keep particulate contamination suspended and filterable — protecting servo valves and maintaining press accuracy across thousands of production cycles. |
Mineral HLP vs. Synthetic PAO Hydraulic Oil: Which Is Right for Your Press?
While mineral-based HLP hydraulic oil (ISO VG 46 or ISO VG 68) remains the most widely used hydraulic fluid in Indian industry, high-cycle ceramic press operations are increasingly switching to synthetic PAO hydraulic fluid. Here’s a direct comparison for KEDA press operators:
| MINERAL HLP OIL | SYNTHETIC PAO HYDRAULIC FLUID |
| Established industry standard | Up to 3x longer service life (cost-efficient long-term) |
| Lower upfront cost | Lower friction = electricity savings |
| Shorter service life | Superior varnish & oxidation resistance |
| Adequate for moderate conditions | Ideal for high-heat Gujarat environments |
| Higher motor load over time | Better ROI for high-cycle ceramic presses |
