IMPA: 617511

Air Operated Grease Lubricator – IMPA 617511

This air operated grease lubricator (IMPA 617511) is a reliable and efficient solution for shipboard lubrication tasks. Designed for the demanding marine environment, it delivers continuous, high-pressure grease to bearings, winches, cranes, rudder shafts, and other deck equipment. By harnessing compressed air, the lubricator eliminates the need for manual pumping, saving crew time and reducing fatigue during maintenance routines.

The unit features a robust, corrosion-resistant body that withstands salt spray and harsh weather conditions. Its adjustable output allows precise control over grease volume, ensuring accurate lubrication and minimizing waste. With a large capacity reservoir and intuitive refill process, the lubricator is built for prolonged operation with minimal downtime, making it an essential tool for any ship chandler inventory or marine maintenance kit.

Engineered for compatibility with common NLGI 0-3 greases, this air operated grease lubricator meets the rigorous demands of commercial shipping, fishing vessels, and offshore installations. Whether used in the engine room or on deck, it provides consistent performance and long service life, backed by a safety relief valve for secure operation.

Frequently Asked Questions

What air pressure is required to operate this grease lubricator?

A compressed air supply of 4 to 8 bar (60–120 psi) is required. Lower pressure may reduce output, while higher pressure can be adjusted with an external regulator.

Can this lubricator handle all types of grease?

It is designed for NLGI grades 0 to 3, which covers most marine greases. Always use clean grease that meets the specifications of your equipment to ensure optimal performance.

Is it safe for use on ships with explosive atmospheres?

As an air-operated unit, it is inherently safer than electric equivalents. However, in explosive atmospheres, follow safety regulations, use conductive hoses, and maintain proper grounding to prevent static discharge.

How often should the reservoir be refilled?

Refill frequency depends on usage. The 5-liter reservoir typically lasts an entire shift for normal greasing tasks. Refill when the grease level appears low, and keep the lubricator clean to avoid contamination.
