Handling hot media liquids in all safety Many industrial processes require heating or cooling to control their process characteristics. Only when predefined parameters of the processes, like temperature are obtained, the process can be started. Maintaining a constant temperature level or changing temperature conditions can easily be done by the use of indirect heating by means of thermal fluids. To obtain the exchange between the user and the heater, thermal fluids are warmed up and circulated in closed loops. The operating temperatures of these thermal fluids loops varies mostly from 100...

FLOWSERVEHot water pumps for up to 150 °C (302 °F) ZLN - The standard hot water pump Up to a temperature of 140 °C (284 °F) and when properly selected, the ZLN, a standard water pump as per EN 733, can be used with uncooled, balanced mechanical seals. Product circulation ensures that the mechanical seal is permanently surrounded by the medium, thus preventing dry running. ZDt - The hot water inline pump The economical inline design is becoming increasingly popular in hot water applications, because it can be installed inline in any pipeline system and thus compensates for pipeline forces in...

Handling hot water requires very special pump designs as the operating pressure increases exponentially with the temperature increase. Special developments of the seal housing are integrated to achieve exceptional long MTBF times by guaranteeing the optimal seal faces lubrication under all circumstances. Many pump and mechanical seal manufactures offering standard pumps with uncooled mechanical seals up to 180 °C (356 °F). Praxis however has proven that the poor lubrication characteristics of water under these extreme pressure and temperature conditions lead to short MTBF times of the...

Hot water pumps for up to 350 °C (662 °F) In opposite to water, organic or synthetic heat transfer media offer the option of heating, cooling or controlling temperature without high system pressures. Operating at temperatures of up to 350 °C (662 °F) is possible in pressure less systems, and the upper temperature limit is currently 400 °C (752 °F). In connection with developments in the area of heat transfer installations and their liquids, the standard DIN 4754 has been compiled. Among other things, this standard specifies the safety requirements and the operation of pumps in thermal oil...

Thermal oil pump with magnetic coupling up to 400 °C (752 °F) Based on an increasing environmental consciousness, tighter regulations (such as TA-Luft, German Technical Instructions on Air Quality Control) and the justified demand for more safety, sealless pumps are increasingly being used. In particular, when pumping synthetic heat transfer media, which can be classified as hazardous to health, magnetically coupled pumps have become the technology of choice. A hermetically sealed magnetic coupling, however, is also the optimal solution when it must be ensured that the heat transfer medium...

Hot water and thermal oil pumps Hot water pumps up to 150 °C (302 °F) uncooled Thermal oil pumps up to 350 °C (662 °F) uncooled Because of its low environmental impact and high specificheat capacity, water is preferred in the temperature range for up to about 200 °C (392 °F). Due to the steam pressure, which increases greatly as the temperature rises, organic liquid heat transfer media are preferred in the temperature range from 200 °C (392 °F) to 400 °C (752 °F). Range of organic heat transfer media
