Rotor in place:
the secondary
CIP o-ring is not engaged
against the secondary CIP
front sleeve. The rotor
compresses the wave spring
to push the sleeve back.
Rotor removed:
the
secondary CIP o-ring
is
engaged against the
secondary CIP front sleeve –
no leaking will occur during
Rotor-out CIP. The wave
spring pushes the sleeve’s
larger diameter forward to
seal the pump body.
