Everyone’s talking about them, but what’s the hype?
Right now, Australia’s outdated HVAC industry is infamous for its drawn-out installation times, ever-increasing onsite labour costs & complicated tenders involving far too many suppliers.
Prefabricated pump skids seem to be the answer we’re looking for.
Here at Masterflow, we’ve spent over 20 years problem solving and triple testing our solutions to come up with our very own, house-made pump skids!
In this article, you’ll discover exactly what prefabrication is, which issues it solves, and, like any new development, what fresh problems it might bring to the table.
The package starts with a hot-dipped galvanised steel base frame, which supports a concrete-filled inertia bases that sit on engineered spring mounts.
Suction and discharge pipework is bolted to the pumps and supported by either welded steel frames or heavy-duty, fully adjustable galvanised 50mm-100mm slotted tube.
The pipework is hung from the welded steel or slotted tube frame (whichever is specified) using the specified springs and appropriate galvanised pump clamps.
The Design Process
Every step of construction follows our documented process ensuring every product is built to drawing specifications, welding is to the AS1554 code, and inertia bases are filled with the correct concrete MPA specification.
As the assembly line proceeds, attention to detail is critical and every step must be signed off. For instance, the building of the pumps to perfectly match the pump curve requirements often exceeds over 100 individual steps to complete.
Skid-mounted pump packages are delivered to site pre-piped and welded – the only thing you’ll require onsite labour for is to drop the skids into place, weld the building pipework to the skid pipework, and connect the electricity.
What could go wrong?
There are some potential issues here:
- Freight will cost more because of the increased size and weight of a prefab unit in comparison to a single pump or tank
- Because of this weight, a crane would likely be needed to lift the skid from the delivery vehicle into the building, which is another added cost
- Pump skids aren’t usually suitable for existing plantrooms (e.g. plantrooms that are being redone) due to the restricted installation space
But check out what’s in it for you! (and us…)
Because there’s a reason we’re promoting this.
If we supply you a pump skid, we’re actually supplying you far more than we would in the traditional manner of pumps and other equipment on its own.
And the removal of the need for so much pipework onsite means you don’t have to deal with 10 different companies just to install a couple of pumps.
The cost of labour is heavily reduced, due to less onsite work needing to be done. This means less plumbers, welders, electricians… the list goes on.
Instead of trying to coordinate both the arrival times and pay packets of 7 plumbers, 6 welders and 8 electricians, you can focus your attention on a single plumber, who’ll be simply linking the skid mounts to the building, a welder, who’ll ensure those connections are secure, and an electrician, who’ll hook up the skid control panels to the building’s power.
We’ll take care of everything else:
- Design and drawings produced in-house using industry leading software
- Fabricated steel work manufactured in our factory
- Every skid-mounted pumpset assembled in-house
- Performance testing of the system
- Documentation and test certificates provided for all aspects of the build
- Support with commissioning if ever requested
