Heat Transfer Pump

Heat Transfer PumpA Heat Transfer Pump is a type of centrifugal pump which conveys hot or cold fluids for heating or cooling purposes. It can vary from hot media up to 400°C or media as cold as -100°C. Different media can be used depending on the application in question i.e water for heating, glycol mixtures and heat transfer oils (HTF).

Hot Water Pumps are generally used up to 230°C. It is very rare to have a hot water pump higher than 150°C.

Heat Transfer Fluid (HTF) Pump circulates thermal oil and are generally used up to 300°C as vapour pressure are only a few bars.

A Heat Transfer Pump design/ specification?

Applications for a Heat Transfer Pump:

Many industrial processes require heating or cooling to control their process characteristics. Heat Transfer Pumps are normally used in the controlling of processes and reactions in vessels.

To circulate these thermal fluids, volute casing pumps are widely used. Depending on the temperature and heat transfer media, Flowserve SIHI have developed different type of pumps in order to circulate the fluids in the most efficient and economical way.

Why do End Users often have a preference for Mechanical Seal Magnetic Drive Pumps?

End users will frequently specify Mechanical Seal Magnetic Drive Pumps where large pressure flocculation’s takes place as some of the fluids are very ‘searching’ in their nature to find an exit/leak path. It is important to contain these fluids which possess a fire risk at elevated pressures.

The ingenious and well proven design over many decades implies a “heat barrier” system which isolates the mechanical seal from the mainstream of the pumpage. This means that the mechanical seal operates at a much lower temperature than the process thus ensuring reliability and additionally does not require any cooling from an external source.
