John Crane Safematic has launched an enhanced version of its Safeunit seal water control system for increasing the reliability of pumps and process machinery while reducing water consumption levels by up to 80%. The new Safeunit Ultima is designed for use in harsh operating environments where high temperature, high pressure and chemically aggressive elements are present. This makes it suitable for extreme applications found in pulp, paper and chemical industry processes, plus a wide variety of mining and general industrial uses. The new Safeunit Ultima not only controls and monitors seal water flow and pressure, but also reduces seal water consumption. It simplifies the initial set up of the seal water system and can be adopted as a standard component of the seal water system, thus eliminating the usual need to accommodate a variety of piping components, valves and couplings. It can also accommodate greater operating temperatures (up to 100C) and provides an optional 50bar pressure capability. The new design also incorporates an integrated check valve and a glass-fronted display. Moreover, the new flow meter design reduces internal pressure loss during operation.
