Need advice on FX hand pump lube

[slow_runner]

The FX hand pump is due a service. It was bought second hand some time back without instructions.
We have the schematic AND the digital photos
Courtesy of Airguns of Arizona, the manual speaks of Fuchs Renolit RHF-1 grease.
So, onto the the local FX agency; no joy there for spares or lube.
Next, I rang Fuchs Lubricants NZ; they will be able to help, right?
No joy there either, in fact they couldn't tell me anything about it at all.
I have rang around the place and no joy. What is this mysterious Fuchs Renolit RHF-1 that no one appears to be aware of, or have cross reference to?

We are not at our wits end yet but before that time arrives, has anyone got the name of a compatible grease that will function as the recommended grease from FX, or better?

Cheers.

Hills pumps are basically the same,

me, well i just use 3-in-one oil, been pumping for years !!

I had the same problem, could not find RENOLIT-RHF1 anywhere

The only thing that cropped up was this:

Although I would think it would be OK to use the same silicone-based grease that Hill does.

Pse don't use 3-in-1 in these high pressure pumps, it could be very dangerous!

Please explain why

A normal mineral oil would be dangerous if used with high pressure &/or pure Oxygen, but poses absolutely no risk what-so ever with compressed air.

? what is the difference between "high pressure" and "compressed air"? all these pumps produce highly compressed air, which in the presence of a fuel (such as mineral oil)
is quite capable of sustaining combustion. It does not need to be pure oxygen, no?

Yes, it does need to be Oxygen (or Oxygen rich) for there to be a serious risk of combustion, (unless you are atomising a specific combustible fuel like diesel in an engine) the only risk with 3 in 1 in a compressed air pump is possible contamination.

Compressed air is just that it is atmospheric air compressed, and the atmosphere is 78% Nitrogen & less than 21% Oxygen, so the inert N2 acts as a "damper" to the O2 content.

I clearly stated "high pressure &/or pure Oxygen" with the Oxygen underlined.

Oxygen and Compressed Air are two hugely different things and have markedly different characteristics under pressure, while pure Oxygen is volatile even at atmospheric pressure.

Thanks Angry and BB
I did come across that LIQUID8R, however nothing local, only from the USA for a few American dollars with a healthy freight rate.
It would appear that RHF1 is an industry classification for extreme pressure/temp range?
Will be making more enquiries on the dognbone today.
