Part no: 15564

The Environmentally Acceptable Gear Lubricant delivering superior anti-wear, EP and oxidation protection even under severe conditions

  • Exceeds the requirements of DIN 51517 part 3
  • Excellent equipment protection
  • Superior thermal stability
  • ISO 68, 100, 150, 220, 320 and 460

For thrusters, some CPP designs and deck equipment

BIOGEAR XP is a range of biodegradable, high performance, extreme pressure (EP) gear lubricants with excellent anti-wear and micropitting performance, available in ISO 68, 100, 150, 220, 320 and 460 viscosities. These lubricants are based on fully saturated synthetic esters with a high degree of renewability and use state-of-the art technology.

VGP Compliance Statement
ISO 9001
ISO 14001

BIOGEAR XP is designed for use in sensitive environments where there is a potential for fluid loss to occur, for example from thrusters, some CPP designs and deck equipment.

BIOGEAR XP is miscible with common mineral based gear oils, but in line with good practice, old lubricants should be drained completely to avoid any risk of additive incompatibility and ensure that the full benefits and performance are achieved. Water content should not exceed 0.1% and any free water must be separated off on a regular basis. Unlike the HYDROX range, these lubricants do not emulsify in water.

BIOGEAR XP achieves a biodegradability of greater than 60% in the 28 day OECD 301B test. These products are considered non-toxic in the marine environment based on the following results:

LC50 exceeds 100 mg/lEC50 exceeds 100 mg/lEC50 excedes 100 mg/l

BIOGEAR XP meets the detailed ecological definitions and requirements laid down in the 2013 Vessel General Permit (VGP) published by the US EPA in March 2013.

Extended fluid lifeFewer fluid changes, less equipment downtime and lower overall cost of ownership
Excellent resistance to micropittingProtects the gear teeth against fatigue wear resulting in less down time
High EP protectionAbility to withstand shock and high loads
Excellent water separationEnables easy removal of free water
Good hydrolytic stabilityResists breakdown of the lubricant by water in high temperature situations
Wider operating temperaturesProtects equipment from -25ºC to over +100ºC
Superior oxidative stabilityLess sludge and system failures, longer fluid life and less fluid thickening
Good elastomer compatibilityCompatible with most sealing materials including Nitrile and Viton
Biodegradable and minimally toxicLower environmental risk
