Industrial Oil HFC 4631 Water-Glycol Fire Resistant Hydraulic Fluid

Product Description

HFC 4631 water-glycol ire resistant hydraulic luid is highly reined ire resistant hydraulic luid taking water and glycol as base luid with high level multi-functional additives such as antiwear agent, anti-oxidizer, rust inhibitor, defoamer and so on. According to international standard classification, it belongs to water-glycol ire resistant hydraulic luid of ISO-L-HFC type.

Advantages
􀅒 Excellent ire resistance, ensuring application safety in case of high temperature and contact with open lame
􀅒 Extremely low freezing point, ensuring easy startup in condition of low temperature
􀅒 Perfect high temperature stability (stable real solvent), no deterioration in long storage period of 2 years
􀅒 Good gas/liquid phase anti-rust ability, and anti-corrosion performance for copper, meeting anti-rust requirement for gas and liquid phases
􀅒 Outstanding lubricity, ensuring lubrication and service life of hydraulic oil pump
􀅒 A long service life not less than 10,000h under normal operating mode and work conditions

Performance
The product meets the following specifications:
􀅒 Q/SH PRD122-2008

Applications
􀅒 Important ire resistant hydraulic media comprehensively used in hydraulic system in conditions of open lame and high temperature
􀅒 Suitable for hydraulic system requiring ire resistance in such industries as steel, coal mine, light industry, chemical engineering, machining, plastic processing and so on
􀅒 Applied temperature range: -50'C~60'C; applied pressure: 20MPa

Typical properties


Precautions
􀅒 The product can’t be used together with mineral type hydraulic oil
􀅒 Checking water content of the product periodically in order to reduce its ire resistance
􀅒 Normally, not exceeding 55'C for open type oil tank and 65'C for close type oil. In case of high temperature, hydraulic viscosity to be increased by excessive evaporation of wavter, application effect to be affected
