Nice construction kit of a wooden Oil pump. With this construction kit children learn how to read a contruction manual, how to handle tools and connect wires.
This pumpjack is 227 mm tall and has been designed as a wooden tool, which results in an archaic looking design.
Energized by a battery, this kit behaves like a crank which transforms the motor’s rotation into an up- and down pumping movement.
The mechanics of this pump is documented in a detailed manual.
