Sanitary Tank Connections
Application
The Benney Silo Seal (Tank Spud Seal) was developed to provide a sanitary
connection in storage vessels. After installation the diaphragm is flush
with the inner vessel wall. A seal at the process face eliminates dead
space or pockets where bacteria can grow or CIP liquids can accumulate.
This seal is designed to integrate with spray ball cleaning and automated
clean in place systems (CIP).
The Silo seal is particularly suitable for installation in the bottom of a
vessel where other process connections would leave a cavity or dead space.
Configuration
Differential or Gauge pressure. In all cases a Low Volume cover flange
must be fitted to all D.P type transmitters to reduce fill quantities and
therefore reduce errors induced by ambient temperature change. Gauge
pressure transmitters require a G-1/2" process connection. The silo seal
consists of two basic components, the outer spud or weldment and the inner
removable silo diaphragm seal. Installation is achieved by cutting a hole
in the vessel wall and welding the spud in the desired location. The
diaphragm seal is slid into the spud and fastened using either a clamp or
nut. A sanitary o-ring seal is made at the inner wall surface. |
