Automatic water filter extends seal effectiveness
November 1st 2006 John Crane says that it has extended the effectiveness of its Safematic range of seal water control systems with the launch of SafeJet - an automatic mechanical seal water filter that provides filtration by removing all soil contaminant particles larger than 50 pm. The SafeJet unit features a special technology that uses several laminar filter elements to create a reliable and self-cleaning micro filter process. The flow direction during filtering is from inside to the exterior, with the impurities filtered out on the inner surface of the filter elements. The pressure loss during normal operation is just 0.1bar. There are no moving or wearing parts which ensures long life, costeffective operation and maximum reliability. Construction materials to AISI 304 are provided as standard, with AISI 316 stainless steel as an option. The flush cycle automatically removes impurities to drain and is activated by opening the SafeJet's integral flush valves. This flush impurities, which requires only a very small volume of water compared to the output, can be controlled by the adjustable timer unit that is supplied as standard, or by an optional pressure difference control.
