Radial Piston Hydraulic Pump - Battery Operated Submersible Water Pump - Manual Vs Electric Breast Pump.
Radial Piston Hydraulic Pump
a water pump that uses the kinetic energy of flowing water to force a small fraction of that water to a reservoir at a higher level
Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic.
a device that converts mechanical force and motion into fluid power.
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders point outward from a central crankshaft like the spokes on a wheel. This configuration was very commonly used in large aircraft engines before most large aircraft started using turbine engines.

Each piston head is connected to a standard LEGO connecting rod. Opposing connecting rods are connected together by a thin 1x7 liftarm. There are 8 thin liftarms in total. The liftarms just float, but the whole operation works very smoothly.
