Cartridge seal cuts costs and product leakage
The John Crane 4610 cartridge seal reduces maintenance and running costs, product leakage and equipment downtime.
Units predict seal and packing failures in advance through changes in pre-set flow and pressure values, with automatic control allowed by the use of alarm sensors.
Seal water leakage is also detected to avoid extra heating and evaporation costs or expensive product quality problems such as dilution.
Simplifying pump set-up and servicing, the system has a 'unique' non-clog valve and can be cleaned with the equipment running.
Options include electrical alarms and LCS-leakage control.
Experience in the USA showed a mill with 300 pumps achieving annual savings of $300,000 through a flow reduction of 4 litres/min per pump.
