Gear pump for thermal fluid (350ºC)

Description

Design awarded by the European INNOWWIDE project, that provides funding to SMEs for their innovative solutions.

Description

• Gear pump for thermal fluid/heat transfer fluid installations, up to 350ºC.
• The helical gears allow a smoother and quieter operation of the pump.
• It is a self-priming pump. That is to say, with the installation empty, the pump is able to aspirate the liquid causing a vacuum pressure in the suction pipe.
• The design integrates a built-in safety valve in the gear casing that is capable of relieving the pressure in case the working limits are exceeded.
• It is suitable for any heat transfer fluid application in the industry up to temperatures of 350ºC. It facilitates the assembly of subcircuits due to its flow rate adjustment, what represents a significant energy saving.
• It is a monoblock version with a standard IEC motor mounted by rigid coupling between the pump shaft and the motor shaft end, and fastened by means of a flange. This ensures optimum alignment of the equipment.
• In addition, the assembly is supported at up to four different points, consisting of three deep groove ball bearings and a front bearing that, apart from providing stability to the shaft, also acts as a fluid restrictive ring.
• Mechanical seal NV-2 Type, according to EN12756 standards, with independent direction of rotation.
• A finned heatsink casing has been designed to considerably reduce the working temperature of the pump in the area of the mechanical seal and bearings.
• Ideal for VFD operation, as it ensures that the assembly is not misaligned as it is a completely solid shaft.
• Possibility of installation in explosive atmosphere in accordance with ATEX directives.
