How misalignment, imbalance and deferred maintenance quietly drain your plant, and what you can do about it.
By the Flecor Team · Published May 2026
If you work in mining, processing, manufacturing or utilities in Western Australia, you already know that unplanned downtime is one of the most expensive things that can happen to an operation. A single unexpected shutdown on a processing line or pump system can cost tens of thousands of dollars in lost production, before you even count labour, emergency call-outs and the stress of getting a repair crew on site fast.
What surprises many plant managers and maintenance teams is how often that downtime was preventable. Not through massive capital investment or a complete equipment overhaul, but through the kind of routine, precision-focused maintenance that gets deprioritised during busy periods and forgotten until something fails.
That’s the gap Flecor was built to close.

The Hidden Cost of ‘She’ll Be Right’ Maintenance
There’s a particular culture in the WA industry, we’re proud of it, where people get things done, improvise when needed, and keep things moving even when conditions aren’t ideal. But that same pragmatism can quietly work against you when it comes to rotating equipment.
Here’s what typically happens: A pump or fan or conveyor drive starts running slightly rough. Vibration increases a little. There’s a new noise, but it’s not that bad. The team is busy, a shutdown isn’t scheduled, so the decision is made to keep going and monitor it.
Six weeks later, the bearing fails. Or the coupling disintegrates. Or the shaft develops a crack. Now you have an emergency, a safety incident waiting to happen, and a repair that costs four times what a scheduled fix would have.
This isn’t a criticism; it’s just how it goes when maintenance teams are stretched, and equipment keeps running. But the data consistently shows that the cost of reactive maintenance is significantly higher than preventive maintenance, and the gap only grows the longer a fault is left unaddressed.
The Two Faults Behind Most Rotating Equipment Failures
Across our work with mining, processing and industrial clients throughout Perth and regional WA, two underlying issues come up again and again as the root cause of premature equipment failure:
1. Misalignment
When a motor and its driven equipment, pump, fan, gearbox, compressor, are not correctly aligned, every revolution creates lateral and axial forces that the bearings, seals and coupling were never designed to handle. The equipment still runs. It might run for months. But the wear is accelerating the whole time.
Signs of misalignment include increased vibration, unusual noise, premature bearing failures, excessive seal wear and couplings that need replacing more often than they should. If any of these sound familiar, misalignment is a likely contributor.
The fix, precision laser alignment to OEM tolerances, typically takes a matter of hours, and the difference in vibration readings is immediate and measurable.
2. Imbalance
Rotating components, fans, impellers, rotors, pulleys, drum shells, are manufactured to be balanced, but over time they change. Material builds up or wears unevenly. A blade gets damaged. A weld is added. The result is a component that is no longer balanced, creating cyclic forces that transmit through the entire drivetrain.
Imbalance is one of the most common sources of vibration in industrial equipment, and one of the most straightforward to correct. Dynamic balancing, either onsite with our portable equipment or in our Perth workshop for components up to 5,000kg, restores the component to specification and eliminates the excess load on bearings and structure.

What Vibration Analysis Tells You Before the Failure Does
One of the most powerful tools in modern maintenance is vibration analysis, and it’s still underused across a significant portion of WA’s industrial base.
Using advanced diagnostic technology, Flecor can detect early-stage faults in rotating equipment including pumps, motors, gearboxes and compressors. Faults that haven’t yet caused a failure, but will. This includes:
- Developing bearing defects weeks or months before failure
- Early-stage imbalance and misalignment
- Resonance issues that amplify structural loads
- Looseness in mechanical fastening
- Gear mesh problems in gearboxes
The value of this isn’t just knowing something is wrong, it’s being able to plan the repair on your schedule, not the equipment’s. A bearing replacement during a planned maintenance window is a routine job. The same replacement after an unplanned seizure can mean days of downtime, sourcing emergency parts, and significant secondary damage.
Why Multi-Trade Capability Changes the Equation
One of the structural problems with industrial maintenance in WA is the number of contractors involved on a typical job. You might have a mechanical fitter from one company, an electrician from another, and a welder from a third, each working from a different work order, communicating through different channels, and accountable to different supervisors.
The inefficiency of this model is well understood by anyone who has managed a shutdown or a complex repair. Scope gaps emerge. Trades wait on each other. Something that should have taken a day takes three.
Flecor was deliberately built as a multi-trade operation to address exactly this problem. Our team covers:
- Mechanical maintenance and fitting
- Laser alignment and Dynamic balancing
- Structural and precision welding
- Licensed electrical work including switchboard upgrades and VSD installations
- Shutdown support and crew mobilisation
Every trade is in-house. We don’t sub-contract your work to others. That means one point of contact, one set of safety inductions, one invoice, and a team that actually communicates with itself. For our clients, the difference in how a job runs is immediately noticeable.
Perth-Based, Built for WA
We’re a Western Australian company. Our people have worked across WA’s mining regions, processing facilities and industrial sites for years. We understand what it means to work in the Pilbara heat, to mobilise quickly for a regional call-out, or to meet the specific safety requirements of a tier-one mine site.
We are also proud to share roots with Sacor, a recognised leader in centrifugal separation technology with a long history serving the Australian industrial sector. That connection gives our team a deep familiarity with precision rotating equipment that goes beyond the generalist maintenance provider.
Our clients range from large mining and processing operations to mid-size manufacturers and utilities providers. What they have in common is that they need maintenance work done properly, on time, and by people who understand the equipment they’re working on.
| If your equipment is running but you’re not sure it’s running well, that’s worth a conversation. Flecor offers initial assessments, vibration analysis and a free consultation to help you understand where your maintenance risk sits.
