End cover

The end cover improves operator safety and
provides an additional barrier to the ingress
of process material and cleaning agents

Positive retention to the housing is provided Product introduction
by four circumferential interlocking areas,
which require a locked cover to be rotated
before it can be removed

In the locked position, each of the four
“teeth” on the end cover are secured in posi- A
tion by two adjacent housing teeth This
helps protect against the end cover being
dislodged accidentally or during cleaning

The resistance to rotation provided by the
inter-locking teeth must be overcome before
the cover can be rotated
The end cover locking mechanism and sealing features are patented.
The end cover is designed to be routinely
opened for inspection and then re-locked
Both the housing and the end cover feature
laser marked lock and unlock symbols, so
that the end cover lock status can be easily The housing marker aligns with the end
confirmed cover symbol:

Twist to lock or to unlock (1/8 turn), with no ○ a circle – end cover unlocked, ready
tools required to pull away or to relock
● a filled circle – end cover now correctly
locked in position

of the end cover on completion of the tests, confirmed no soiling
