Can I Use Just One Type of Hydraulic Oil?

Yes what you are saying correct

We are phasing many problems while we are working,

We got some hydraulic oil leak,

Actually, Our Maine problem as a line maintenance that, we have different manufacturers types of pump and head,

This case forces our crew to use some times different machine in order to use dies for crimping conductor depending on sleeves size required.

MF - Massey Ferguson (other tractor manufacturers are available)?

As Sparky stated above, check the manufacturer. I've seen hydraulic systems need to be torn down, evacuated, and replaced because someone put the wrong type oil in (ie. correct viscosity, but different manufacturer). The seals in the pump melted and contaminated the valves. hoses, and just about every component in the system.

Hello lineman380

What type of oil recommended the vendors for each equipment?

The recommended oils are compatible?

Sometime the manufacturer indicating ISO viscozity grade and some brands of oil to be used and in this way you could select same brand of hydraulic oil for both sumps.

Regards

Most hydraulic oils are viscosity 32 or 46 depending on the ambient temperature, and mineral base. In that regard, you could choose a 46 viscosity and use the same for both systems.
In the case you know the viscosity of the most sensitive or most important of them 46 or 32, you may choose that viscosity as standard for both systems.

The other difference in hydraulic oil characteristics is the level of wear resistance additives. The basic hydraulic oil are called R&O for rust and oxidation inhibitors. Then, there are several stages of antiwear (AW) additivation determined as Zinc. for example a high AW hydraulic may have 500 ppm of Zn compound . Last but not least, there are Zn-free hydraulic oils, that means the antiwear is based in other substances that are not affected by moisture like Zn compounds do.

I am sure you don't have any case of special hydraulics required such as fire resistant, biodegradable, dispersant, MEHF, synthetic, etc.

A Zn-free hydraulic with 46 viscosity may resume the requirement of most hydraulic oils for your equipment.

Post the specifications here for those oils and we can tell you if you can use one for both systems.

Thanks...Thanks for your nice reply

Just give me please some time to collect specifications for them

Thanks and best regard

My 50 ton enerpak wants to use its special oil so thats what I use. If you can find some with the same specks go for it. However some hydro oils are anti foam so you had best check real hard in your manual or email the company and ask them for sure.

The "special" oil is a normal oil packed in yellow containers and sold at a lot higher price.

Dear sir,

Please refer the pump manufacturer`s catalog for recomended hydraulic oil. Also, following points are important to consider:

1. The ambient temperature around pumps location. If the temperature is 20 to 45 Deg. Celsius, use the oil of 45 viscosity grade. If the temperature is more, use the oil of higher viscosity. Temperature makes the oil less viscos. At temperature less than 20 Deg Celsius, oil of less viscosity grade should be used as grades are given for temperatures ranging between 35 to 45 deg. celsius.

2. Pumps with seals of natural rubber should be used with organic oils as the synthetic oils damage these seals.

3. Pumps running with more pressure generate more heat and the viscosity is reduced after some time. Less viscosity of oil causes bad lubrication and this may damage the pump.

4. Running hours and cooling system are other important factors. Regular cooling by heat exchangers increases the life of pump and the oil as well.

Excellent Points to be considered.

Thanks for your help

Thank you to the GUEST comments above. just to build up on your fears:

There is no need to follow the pump manufacturer`s catalog for recomended hydraulic oils. Just follow the specifications for the oil required by the manufacturer.

1. The ambient temperature around pumps location: If the pumps are subject to wide temperature changes, outdoor equipment, all year round usage, then it is better to apply a Maximum Efficiency Hydraulic Fluid, MEHF www.mehf.com that keeps a more uniform viscosity at different temperatures due to a high viscosity index (over 150)

2. Pumps with seals of natural rubber should be used with organic oils as the synthetic oils damage these seals. Yes, avoid PAGs and phosphate ester based hidraulic fluids. synthetic PAOs and mineral base are acceptable. There are different mineral oil bases that are considered better for hydraulic fluids, called Group II ane Group III oils, some manufactureser call them erroneously 'synthetic' and are much resistant for oxidation and long term application.

3. Pumps running with more pressure generate more heat and the viscosity is reduced after some time. Less viscosity of oil causes bad lubrication and this may damage the pump. Refer back to point 2: use MEHF, use synthetic PAOs or group III oils in this case

Hope this helps

Dear sir,

Thanks for elaboration on the four `Important factors` given by me
