Common Questions about GreaseMax® Single Point Lubricators




GREASEMAX®USA is the sole distributor within the United Sates of the German engineered automatic lubricating units which is rapidly becoming Internationally renowned for it’s proven reliability, cost-effectiveness, direct maintenance savings, improved production availability, reduced maintenance down time and elimination of some Occupational Health & Safety issues.

GreaseMax® is manufactured to the highest Quality Standards. As part of this commitment we will not introduce any element into the design of GreaseMax which can contribute to unreliability- such as electrical or mechanical components, plastic bodies, or by reducing components or using cheaper material including lubricants, to save on production costs. Grease Max® units are manufactured in Offenburg - Germany. Marketing Headquarters for GreaseMax® International is located in Australia, managed by Delta Distribution Pty Ltd.


How do I know GreaseMax® is working, when the position of the piston can't be seen?
Firstly, remember that GreaseMax® has only one moving part, (the piston), no mechanical parts, and no electrics. It uses an operating system proven to be absolutely reliable over 25 years. The manufacturer has stringent quality control to ISO9001 standard. It is very unlikely that non performance will be encountered.

The GreaseMax® design is fail safe; the starter cap cannot be screwed in without turning the activator screw down, which in turn can only break the seals and release the controlling element into the chemicals. The only possible result then is the production of gas which must push the piston forward and the lubricant out. The gas is retained in a gas tight neoprene bag and also as part of the fail safe design by the gas tight seals on the piston and the double O-rings on the starter cap.

However, to be assured, check the following:

Simply feel the bearing temperature if safe to do so, or use a thermometer.

A fresh discharge of grease around the seals will be visible when GreaseMax® is operating.

If I have a worn bearing will GreaseMax® discharge faster?
No, definitely not. GreaseMax® is self regulating and is a true automatic lubricator. It will maintain it's correct discharge rate regardless of the bearing type, tolerance or operating conditions.

Does the orifice size affect the discharge rate?
No. See page 3, Operation of GreaseMax®.

Is a 12 month GreaseMax® larger than a 1 month?
No, they are all the same size. The only difference is the discharge rates. (see the diagram and notes on page 3).

The plant is regularly stopped, for example at the week end. Will this create a problem with over greasing?
No. GreaseMax® discharges at a very slow controlled rate and the amount of grease it can push into a bearing while the bearing is stopped for a few days will not a cause a problem.
GreaseMax® is able to maintain a fine balance of pressure and if the plant is stopped for short periods, for instance at the week end, the resistance of the grease way is increased. This will temporarily stop GreaseMax®. When the plant starts again, the grease will be released into the moving bearing. (Eventually GreaseMax® would build enough pressure to move grease into the stopped bearing).

Will the 120 grams of grease in the GreaseMax® be enough?
When greasing is done with a grease gun, excess grease is used. Only a very small amount of grease is actually used by a bearing, the rest is wasted. Because GreaseMax® introduces grease into the bearing at a slow controlled rate while the bearing is moving only a small output quantity is required.
Providing the correct GreaseMax® is chosen to begin with, the output will be sufficient. An additional benefit is that the plant will remain much cleaner!

For our application, GreaseMax® output is not sufficient, even with a 1 month unit.
Several GreaseMax® can be grouped together into one line to provide a higher feed rate.

Can we use one GreaseMax® to feed two or more lines?
No, never. The discharge cannot be evenly split, as every bearing has a different grease resistance. Inevitably one bearing will be starved of grease.

We took the unit off and nothing came out!
This is the most common "complaint" or misunderstanding with this product.
GreaseMax® will only show a large and obvious discharge if it has been used on a bearing with a reasonable amount of grease way resistance.
If GreaseMax® is applied to a bearing with little or no grease way resistance (which is common) and GreaseMax® is unscrewed, nothing should come out, except at A VERY SLOW RATE. Remember, GreaseMax® operates in equilibrium with resistance.
This situation has confused many people so far, especially if they have removed the product from one bearing which has some resistance, seen the resulting discharge, and then removed another GreaseMax® from a similar neighboring bearing, which has no resistance and which therefore will not show an immediate discharge.

Why shouldn't GreaseMax® be removed from the bearing during operation?
If GreaseMax is operating under a lot of pressure, when removed this pressure will be lost. The unit may have been at say, half life, so the piston will be halfway down the cylinder. The chemical reaction which produces the pressure is very slow to re-pressurize up to the required pressure the second time may take a considerable period. Under-lubrication during this period may result.
(Note: when first installed there is no problem with the time taken to accumulate pressure as the internal volume in the expansion diaphragm is fully taken up with liquid so pressure develops quickly).

Why doesn't GreaseMax® have a transparent body?
GreaseMax has a steel body for a very good reason. Steel does not deform under the heat and pressure likely to be encountered when using GreaseMax® in some applications. Plastic does. If this were to occur, GreaseMax® would suffer failure.
The disadvantage of course is that the progress of the piston can’t be seen but the advantages in terms of the performance and reliability of the unit far outweigh the disadvantages.

We think it is better to manually inspect the bearings while greasing
As will be apparent, the time spent on manual greasing can be used more efficiently and the expense applied to a better maintenance outcome. If inspections are required they are better done by qualified personnel as part of a Condition Monitoring program. If the bearings are correctly lubricated and then correctly inspected, (which need only be at relatively extended intervals), bearing life will be considerably improved. Maintenance costs will be greatly reduced and the costs of unscheduled production stoppages in terms of lost production and unscheduled maintenance will be lowered.

Why isn’t GreaseMax® adjustable?
GreaseMax® is made to be completely reliable in all conditions. We prefer not to compromise with any design aspect but particularly this one. To make it adjustable would mean added complexity and the addition of electrical components. This would inevitably degrade the reliability factor.

How should GreaseMax® be disposed of?
In the industrial waste. DO NOT leave the expired units lying around for the curious to tamper with. Remember, GreaseMax® contains a small amount of potassium hydroxide and a small amount of pressure for some weeks after expiry. The amount of lubricant remaining in an expired GreaseMax® is very small and does not give rise to environmental concerns for disposal.
