About Our Hydraulic Oil Filtration Service in Kolkata

Hydraulic systems are particularly sensitive to contamination — even particles as small as 5 microns can cause valve stiction, cylinder drift, and pump failure. Ram Engineering's hydraulic oil filtration service achieves ISO 4406 cleanliness levels 16/14/11 and below, protecting servo valves and precision hydraulic components.

The Kolkata-Haldia corridor is a major industrial belt with steel plants, Haldia Petrochemicals, jute mills, and a busy commercial port. With Dankuni Industrial Complex, Kalyani Industrial Area, Haldia Petrochemical Zone, Falta SEZ, and Bantala Leather Complex driving demand for industrial services, our hydraulic oil filtration teams are deployed regularly across Kolkata's key manufacturing zones.

Frequently Asked Questions

What cleanliness level should hydraulic oil be at?
For servo and proportional valve systems: ISO 16/14/11 or better. For standard hydraulic systems: ISO 18/16/13 or better.
How do you filter hydraulic oil without contaminating the system?
We use dedicated clean hoses and flushed connections to prevent introduction of new contamination during the service.
Can water in hydraulic oil damage pumps?
Yes. Even 0.1% water in hydraulic oil causes micro-pitting on pump and motor components, reducing bearing life by up to 75%.
