4639 high pressure ashless anti-wear hydraulic oil
Introduction:
4639 high pressure ashless anti-wear hydraulic oil is refined by deep refining high-quality base oil and high-quality ashless additives.
This product is refined by deep refining high quality base oil and high quality ashless additive.
[performance features]
The special zinc free anti-wear formula can effectively protect the silver containing parts and extend the pump made of silver and silver plated parts
Life span of;
Compared with ordinary HM anti-wear hydraulic oil, the oil has better hydrolytic stability when the system is
A small amount of water pollution can also provide good protection; a good filtration, reduce the probability of hydraulic system blockage and pollution; a good environmental performance, reduce environmental pollution.
[executive standard]
This product conforms to zd.215-2006 standard.
