Two vacuum trucks with identical pumps can perform very differently. The difference is rarely the pump — it's the geometry of the air path between the suction nozzle and the tank.
A vacuum truck is, fundamentally, an air-moving machine. The pump creates the suction, but every bend, junction, and diameter change in the air path costs energy. Get the geometry wrong and you waste pump power fighting your own plumbing.
What CFD Lets Us See
Computational Fluid Dynamics simulation lets us visualise airflow, pressure drop, and turbulence inside the system before we cut any steel. We can spot a sharp bend that's creating a pressure bottleneck, or a tank inlet geometry that's causing turbulent recirculation.
What We Optimise
- Pressure drop across the full suction path
- Bend radii and junction angles to minimise turbulence
- Tank inlet geometry for clean separation
- Filter placement and airflow distribution
Small Changes, Real Gains
On our latest vacuum-truck design, iterating the airflow path through CFD before fabrication let us reduce pressure losses meaningfully — which translates directly into stronger suction at the nozzle for the same pump power, or the same suction with lower fuel burn.
Every sharp bend in a suction line is a tax you pay on every litre you lift. CFD is how we find and remove those taxes.
Validate, Don't Guess
The old way of designing vacuum systems relied on experience and rules of thumb. Those still matter — but CFD turns "this should work" into "we've simulated this and we know it works." Every flow path in our trucks is validated digitally before it's built.
