Functional description
The pump includes:

When the piston (1) rises, the Upper (2) closes or Lower Ball check (3)
opens. The piston (1) expels the product from the upper chamber (V2)
to the outside and sucks the product to fill the lower chamber (V1).
When the piston (1) is lowered, the upper flap (2) opens and the lower
flap (3) closes. The piston (1) compresses the fluid in the lower chamber
(V1) and transfers it to the upper chamber (V2). Since the volume of
the upper chamber (V2) is half that of the lower chamber (V1), a
volume equivalent to the upper chamber (V2) is expelled from the
pump
