Frequently asked questions
What do you build in this puzzle?
Six parts of a small fluid loop: the suction pipe, pump casing, impeller, pump shaft, discharge pipe and a spring-loaded check valve. Drag each one onto its own dashed outline.
In which order should the parts go together?
Any order works. The game only checks whether each part lands on its own outline, and the flow still runs from the suction pipe through the pump and up through the check valve to the outlet.
What does the check valve do in the loop?
It lets fluid leave the pump but blocks it from flowing back. Its spring holds the disc closed whenever the pump stops.
Is this a real pump model?
No. It is a heavily simplified teaching diagram made to show how the parts fit together, not a buildable engineering drawing.
