The BBA BA150 is a robust 6-inch vacuum-assisted centrifugal pump, engineered for high-demand dewatering and flood response applications. With the ability to handle flows up to 475 m³/h and solids up to 80 mm, it’s ideal for stop bank over-pumping, wastewater bypass, and emergency drainage. Its diesel-driven configuration ensures mobility and rapid deployment, while the sound-attenuated canopy allows quiet operation in urban or sensitive environments. Automatic level control and efficient priming make it reliable in fluctuating conditions. Built for durability and ease of use, the
BA150 is trusted by civil defense and regional crews across New Zealand. Also available in an electric version, it offers a sustainable alternative for fixed installations or low-emission zones.

Based on the data, the BBA BA150 stands out as the most efficient option across all key performance areas. It uses the least fuel per hour (5.7 L/h), produces the lowest CO₂ emissions (15.1 kg/h), and requires less frequent servicing with a 500-hour interval, double that of the other pumps. With lower running costs, reduced environmental impact, and longer time between maintenance, it’s the most cost-effective and reliable choice in its class.
To carry out this comparison, we sourced technical data from each manufacturer’s publicly available specification sheets and performance curves. These documents provided the baseline information for fuel consumption, power draw, service intervals, and engine speed.
We selected a fixed duty point, 360 m³/hr flow at 15 meters of head, to create a consistent basis for comparison. This approach allowed us to evaluate each pump under the same operating conditions, rather than relying on variable or ideal-case figures.
Fuel usage values were taken directly from the specification data at the selected operating point. These figures were then used to calculate estimated CO₂ emissions for each pump. We applied the same formula across all models: L/hour x 2640 grams / 1000 = CO2 kg/hour . This gave us a simple, consistent measure of environmental impact based on real-world fuel use.
The same method was applied to service intervals and power draw, allowing a clear comparison of maintenance requirements and energy efficiency. No adjustments were made to manufacturer-stated figures, the comparison reflects the data as published, applied to the same job.
In summary, the BBA BA150 leads the pack in efficiency, fuel economy, and lower emissions, making it an excellent choice for tough dewatering jobs. Its extended service intervals and quiet operation also reduce downtime and site disruption. For those looking to improve reliability and sustainability on their projects, the BBA BA150 offers proven performance you can count on.
