Frequently Asked Questions
What does HM mean in hydraulic oil classification?
HM stands for Hydraulic oil with anti-wear additives (Metal passivators). It is an ISO classification for standard anti-wear hydraulic fluids containing zinc-based ZDDP additives for pump and component protection.
Is HM 46 suitable for vane pumps?
Yes, HM 46 is suitable for vane pumps, gear pumps, and piston pumps. The zinc-based anti-wear additives provide excellent protection for the demanding contact conditions in vane pumps. It meets Vickers, Denison, and Parker pump test requirements.
When should I use HM 46 instead of HV 46?
HM 46 is preferred for indoor industrial applications with stable operating temperatures, where the higher viscosity index of HV oils is unnecessary. HM oils are typically more cost-effective for factory hydraulic systems.
