Centrifugal multistage pump

This is a multi-stage pump designed to pressurize fluids such as water, waste, or food products. It uses a motor and a hydraulic assembly, controlled by onboard electronics and software, to move fluid from an inlet to an outlet. A notable feature is its mounting system, allowing the pump body to rotate around its central axis, and it is specifically designed for 10-60 volt DC power, potentially for use on a floating vessel.

Why it matters: Filed before modern embedded systems and power electronics made sophisticated DC motor control and monitoring much more efficient and cost-effective. This enables more advanced software features for protection and control.
