Low Pressure Seal with Internal Diaphragm OPTIMUS

Product catalog summary

Introduction
The OPTIMUS series is designed for measuring low pressures with a smaller flange connection. It features an internal diaphragm that increases the diaphragm diameter without enlarging the flange size, enhancing accuracy at low pressures. The series is compatible with various ANSI B16.5 and EN 1092-1 standard flanges and is available with a threaded connection. The upper part can be removed for cleaning.

Low Pressure Seal with Internal Diaphragm OPTIMUS-1

LOW PRESSURE SEAL WITH INTERNAL DIAPHRAGM OPTIMUS “Quality Matters” Introduction The OPTIMUS series offers a solution to measuring low pressures on a smaller flange connection. By welding an internal diaphragm, a substantial increase in diaphragm diameter can be achieved without a parallel increase in flange size. Displacement is increased accordingly which in turn improves accuracy at low pressures. The OPTIMUS / OPTIMUS XL can be fitted with a number of ANSI B16.5 and EN 1092-1 standard flanges, making it a versatile seal for use in a wide variety of situations. It is also available with a threaded connection. The upper part can be dismounted for washing the internal part of the chemical seal.
