GRESIUM PULX
NLGI NO. 2 | 3
Product Overview
STARKOL GRESIUM PULX is a premium non-soap grease thickened with polyurea, engineered for extended service life in hi-gh-speed and sealed-for-life bearing app-lications. Its unique formulation provides outstanding oxidation stability, minimal oil separation, and excellent performance at elevated temperatures, making it ideal for applications where relubrication is dif-ficult or undesirable.
The grease offers reliable protection against wear, rust, and corrosion, while maintaining stabi-lity even under high-speed operation. Its long service life and clean behavior make it particular-ly suitable for electric motors, alternators, HVAC systems, and other precision machinery.
• Excellent long-life lubrication properties
• Wide operating temperature range (−30 to +180 °C, up to 200 °C for short periods)
• Very low oil separation and evaporation loss
• Strong resistance to oxidation and corrosion
• Stable performance in high-speed bearings
• Ideal for sealed-for-life and electric motor applications
• NLGI 3 version available for higher consistency needs
