How strong must the evidence be… for us engineers to change current practices???
THE ULTIMATE…HYDRAULIC & LUBRICATION SYSTEM RELIABILITY & PROTECTION
Monthly Archives: May 2020
HYDRAULIC PUMP PROTECTION
A Major Off Highway Machine & Equipment OEM, deciced to try a new concept in filtration, to protect the hydraulic pump & system Pre-Pump.
The vehicle selected for a second phase of testing of the Magnom 2” suction unit “PumpMate” was a ‘Brand New’ production vehicle straight from the factory production line.
This and other test vehicles where assessed and analysed in a combined and concurrent test program that was to replicate normal running conditions for a period of 1250 hrs
Following successful testing of a 2” PumpMate on a prototype machine, the second phase test was initiated to demonstrate what benefits Magnom technology could achieve on a new, optimally cleaned Company production product.
Following the 1250 hr test the machine was returned to the work shops for removal of the test unit and further investigation work.
The Magnon unit was removed by Company technicians and prepared for product disassembly by Magnom staff.
The internal magnetic core was sent for independent testing by the UK Government contractor Qunetiq
The test summary can be seen in full here:– QUNETIQ MAGNOM TEST ANALYSIS DATA
Sample of contamination removed from the PumpMate, the majority being sub 10 micron in size
Even preliminary inspection of the test unit indicated, that the test Magnom had indeed performed extreamly well.
On closer inspection, a significantly higher volume of harmful contaminant than was expected by all, was observed trapped within the cores of the Magnom 2” Pump Mate suction unit.
One surprising aspect of these findings is that, so much harmful contamination had been removed pre-pump from a Brand New & “Clean” production machine.
Clearly the collected contamination consisted mainly of “Built in” Manufacturing debris & contamination generated during the “Break-in” process.

Question!
Would any hydraulic equipment manufacturer or operator allow material such as this to be consumed by the systems pump, causing major damage to the Pump its self and then distributing this contamination plus the pump wear material throughout the entire system…
“IF IT’S PREVENTION WERE POSSIBLE”?
Never before has it been possible To arrest this chain reaction of wear Pre-pump, thus protecting the entire system and bringing about benefits never previously thought possible, and uniquely such is the capacity of the PumpMate, it is designed to be a “FIT & FORGET” installation for most systems.

FUTURE PROOFING OF HYDRAULIC AND LUBRICATION SYSTEMS
Hydraulic & Lubrication System Failure Analysis,
Stop! Premature Pump, Motor, Valve, & Actuator Failure.
What do we know to be ‘The Greatest Threat‘ to reliability of a Fluid Power or Lubrication System :- i.e.?
———————————————————–
Question!
What causes failure of an otherwise
healthy fluid system (apart from excessive heat)?
Answer!
Microfine Contaminants, super sharp and as hard as any component/material in the system, circulating and re-circulating around that system, Flowing between the working surfaces of critical components! Causing wear and degradation of critical components. Threatening the system from within!
Ferrous!…. Steel & Iron… From…Manufacturing, Brake in, and General Wear & Tear
Effectively bits of the system itself… killing the system,
The proposition is a simple one!
1, Remove the worst threat to a system ‘ABSOLUTELY!!!’
2, In ‘Strategic locations’ in the system that deliver the most benefit
3, Where it can have a massive impact on the ‘health’, ‘life’ and the ‘reliability’ of the system.
4, And thus positively effect Customer Experience, Brand Confidence and ultimately Warranty!
Simply “Stop the Chain Reaction of Wear” From the outset !
And prevent the damage to and the generation of wear metals, from critical system components, such as the softer sacrificial metals… Such as… Aluminium, Bronze, Copper, Brass, & White metal.
WHY NOW?
Our fluid industry has become obsessed with conventional Sieve filtration as being the only solution, & this has…
Not changed for 80 + years!
Only now! do we have the technology available to address this remaining problem!
As our industry moves to :-
1, Higher working pressures (5000 & 6000 psi >)
2, & Higher fluid velocities
3, & Closer working tolerances
4, Optimised system designs, rather than over engineered systems.
The need to resolve these historic issues becomes even greater…
REMEMBER!
The particle contaminant size is not important…
What its made of… and the threat it poses to our systems is!
