KACIO B30-1 Mini Brass Centrifugal Water Pump Model for Steam & IC Engines
Hero Section: Give Your Engine a Real Job
A model engine running on a stand is a marvel of mechanics, but an engine performing actual work is a masterpiece of engineering. The KACIO B30-1 Mini Centrifugal Pump is the perfect accessory to transform your static display into a functional pumping station. Crafted from solid brass with an exquisite industrial aesthetic, this pump is designed to be belt-driven by your Steam (perfect for the Whippet), Stirling, or Internal Combustion engine. Watch as your engine’s power is transferred to the impeller, moving a stream of water and demonstrating the fascinating physics of fluid dynamics right on your desktop.
Why Choose the KACIO B30-1?
This pump is built for the serious hobbyist who values both aesthetics and utility.
- Industrial Art: Made entirely of brass, the B30-1 features a stunning golden finish that naturally complements the vintage look of classic steam engines and the KACIO Whippet. It looks like a piece of history.
- Functional Realism: This isn't a toy prop; it is a fully operational centrifugal pump. It features a scientifically designed internal impeller (29.4mm) that uses centrifugal force to displace fluid, just like full-sized industrial pumps.
- Versatile Upgrade: Whether you are building a cooling circulation system for your IC engine or creating a water transfer display for your steam plant, this pump provides the necessary hydraulic function with style.
- Educational Value: It offers a hands-on demonstration of how rotational energy creates pressure differentials to move liquids—a perfect physics lesson for students and enthusiasts.
Technical Highlights: The Expert’s View
- Impeller Dynamics: The core of the pump is a 29.4mm impeller with a combined blade structure (4mm+4mm). As it spins, it throws water outwards, creating a vacuum at the center that pulls more water in from the inlet.
- Flow Architecture: Designed with a 9.0mm internal inlet and a 7.5mm internal outlet, the pump is optimized for the flow rates typically generated by model engine speeds.
- Drive Flexibility: The 4.0mm spindle (with M3 threading) allows for easy attachment of various pulleys, making it compatible with a wide range of drive belts and engine types.

Usage Scenario: The Pumping Station
You mount the B30-1 onto a wooden baseplate next to your Whippet steam engine. You connect the two with a spring belt. You submerge the intake hose in a small water reservoir and—crucially—prime the pump by filling it with water. You open the steam valve. As the engine chugs to life, the pump spins up. Suddenly, a steady stream of water arcs from the outlet hose back into the tank. You have successfully built a closed-loop hydraulic system powered by steam.
Important Tips
- Must Be Primed: Centrifugal pumps are not self-priming. You must fill the pump casing and suction pipe with water before starting the motor. If you run it dry, it will not pump and may overheat.
- DIY Installation: This is a component for custom builds. It does not come with hoses, belts, or a base. You will need to fabricate mounts and plumbing suitable for your specific project.
- Drive Direction: Ensure your engine spins the pump in the correct direction to utilize the impeller's shape for moving water.
