NonFlow Supply System

Features

With the new NonFlow seal supply system it is possible to supply barrier fluid to double and tandem mechanical seals for a broad range of applications. NonFlow systems are equipped as standard with all the necessary system connections and brackets. The system allows for multiple additional components for remote monitoring such as seal temperature monitoring with PT-100 sensors, pressure measurement and leakage detection by flow monitoring.

Advantages

  • Eliminates barrier fluid costs and maintains a steady buffer water pressure
  • Pressure fluctuations in the seal water line are compensated by the pressure accumulator
  • The accumulator can keep the seal pressurized for days even if the supply water line is lost (e.g.in case of power blackout)
  • One system, all the needed functionality
  • Not as demanding about barrier fluid quality since the system has no small orifices that can be clogged
  • No water flow to introduce harmful solids into the system or mechanical seal
  • With an NonFlow-system no other auxiliary equipment is required. (No need for flow meters, valves etc.to adjust pressure/flow)
  • Better running conditions for the seal, with additional cost benefits!

Functional description

The NonFlow system performs all the basic functions of a barrier system for the operation of non-flow capable double and tandem seals:
  • Pressurization of the seal barrier chamber via the barrier water supply line
  • Leakage compensation
  • Compensates pressure variations in the barrier water supply line
  • Cools the seal (cooling loop version)
  • Prevents dry running by ensuring sufficient barrier pressure, possibility of accidental pressure drop minimized
