5.14 Pulp and Paper diaphragm seals (S26KN)
Models 266HDH, 266NDH, 266GDH and 266ADH integrate a direct mount seal on the positive side, having the negative side
reference at atmospheric or vacuum pressure, respectively for gauge or absolute measurements.
The integral seal is available in 1in and 1-1/2in diaphragm sizes specifically designed for pulp & paper industry applications,
providing a flush diaphragm to the process; this solution ensures the measure reliability avoiding all problems of crystallization/
polymerization, typical of pulps having viscosity as in the paper mill.
IMPORTANT.
Use of proper procedures and fixtures avoid the risks of personal injury or plant damage.
The recommended minimum radius of curvature of the tank is 0.91 m (3 feet).
Allowed fill fluids are Silicone Oil DC200
