VGP-Compliant Stern Tube Lubricant

Posted by Michelle Howard

Water in oil lubricated systems is undesirable. In a perfect installation, there would be no seal damage or water ingress, but vessel owners encounter this all the time. Panolin's Stella Maris stern tube lubricant is based on 100% saturated synthetic ester technology with the most effective performance enhancing additives. This fully synthetic ISO VG 68, 100, 150 and 220 Stella Maris stern tube lubricant provides biodegradability and superior lubricity to protect metal surfaces, while meeting new 2013 VGP requirements.

Stella Maris is not an emulsifying lubricant. It readily separates from water. The few emulsifying properties, approximately 800-1,500 ppm, allow Stella Maris to entrap the water and still adhere on the metal surface for lubricity advantages; the water will be released and can be separated in the storage tank.

In a stern tube, if water cannot be separated from the lubricant and the lubricating oil emulsifies, owners are forced to deal with system sludge. The heat of a stern tube will also speed up this process. Emulsifying lubricating oil in an application where water and heat are major factors is a recipe for system failure. That's why Stella Maris offers a variety of benefits.

One of the main products in Panolin's Green Marine line, Stella Maris stern tube lubricant is environmentally considerate, biodegradable and negligibly toxic to marine life. It presents no bio-accumulation and leaves no sheen. In addition, it reduces CO2 emissions by increasing equipment efficiency and conserving resources through longer oil change intervals.

Available in 68, 100, 150 and 220 grades, Stella Maris stern tube lubricant offers protection against lacquer formation, due to its outstanding thermal oxidation stability. It delivers a clear advantage over mineral-based oils thanks to its very high viscosity index. The viscosity will change less than the one of a mineral oil when the system temperature fluctuates. The perfect shear stability will not change the viscosity either, even under very high load and shear stress. A low pour point makes it good for cold start-ups.

Like all Green Marine products, Stella Maris stern tube lubricant offers long-term cost saving, potentially for the life of the equipment. Vessels require less downtime for maintenance. Additionally, owners and operators can reduce costs of used oil disposal.

Besides stern tube lubricants, Panolin offers hydraulic fluids and heavy-duty gear oil, as well as lubricants for stabilizers, deck machinery, compressors and a variety of other applications. With a heritage of over 60 years of Swiss oil technology, Green Marine product efficacy has been confirmed by numerous field tests and eco-labels worldwide.
