one smooth, downward sloping solid base for complete passive drainage.
Simple, but effective.
For maximum cleanability without manual intervention,
Pharmenta's new radial tank bottom valve features a patented diaphragm
perimeter seal that is folded under and anchored on top of a pedestal.
This design eliminates the difficult-
to-drain, difficult-to-flush and difficult-to-clean sump that is found in
all other diaphragm tank bottom valves as a result of mounting the
diaphragm in the valve’s bottom wall.
To minimize worries over batch-to-batch
cross-contamination, the bottom half of the SumpFree™
valve is manufactured of a single piece of stainless steel, free of seams
and seal joints. This eliminates bottom wall crevices and seal seams where
material tends to build up.
In addition, the entire bottom wall is machined into a
continuously declining seamless surface, providing a built-in positive
drain slope that promotes complete, unassisted tank and bottom valve
drainage. The positive drain slope also extends to CIP/SIP inlets mounted
to Pharmenta valves, insuring that complete passive drainability extends
to the entire system.
