Pumping Molten Sulphur

This application note provides an overview of the successful use of magnetically coupled gear pumps to meter and manufacture sulphur derivatives used in the manufacture of surfactants.

THE INDUSTRY

A global manufacturer of specialty and intermediate chemicals that are used in a number of consumer products and industrial applications uses surfactants as the primary ingredient responsible for the foaming and cleaning qualities of its cleaning compounds, detergents, shampoos, lotions, toothpaste and cosmetics.

THE APPLICATION

Molten sulphur is used to produce the sulphur derivatives used to make surfactants. A robust and reliable pump is needed to feed molten sulphur from storage tanks to provide a flooded suction. Molten sulphur solidifies below relatively high ambient temperatures and it increases in viscosity above the optimum pumping temperature.

THE PUMP SOLUTION

Liquiflo 35 series magnetically coupled gear pumps are long coupled to three-phase inverter rated motors for control of the metered molten sulphur.

FEATUREADVANTAGEBENEFIT
External Gear Pump Design Smooth, pulse-free flow Easy to monitor, easy to control
Simple to service and maintain Reduced downtime and less production lost
Accurate, pulse-less output Consistent application of molten sulfur to sulphur derivatives
Magnetic Coupling Containment of the pumped fluid Reduced chemical and environmental hazards - no leakage in the plant
No rotating seals to fail Extended pump operation between servicing means reduced downtime
Leak free pumping No cross contamination of the pumped fluid
Inverter Controlled Motors Motor output speed can be easily adjusted Chemical dose can be adjusted automatically
