The manufacturing of the mechanical parts
like pistons and pins would be possible
with ABS polymer. For the pneumatic
elements a thermoplastic elastomer as
EPDM would be ideal according to its
characteristics. The only metal piece
is the spiral spring.
Allmost all inner elements are
produced by injection.
The exterior ring can be made in
stainless steel or thermoformed
polycarbonate.The pump elements could be
produced by blow molding.
