Canned motor pumps for high temperature applications are used in many technical and industrial processes requiring the supply of process heat.

According to the European EDL directive (final energy efficiency and energy services), 9 % energy savings over a nine-year-period – in comparison to a reference period – should be possible through targeted measures. A current topic is energy savings in industrial refrigeration plants taking natural refrigerants such as NH3 and CO2 as a basis.

The use of multistage canned motor pumps
This article informs about the use of multistage pumps by taking into the account the life-cycle costs and the potential savings of energy.

A contribution to saving energy

In choosing pumps for the forced re-circulation of refrigerants in large-scale refrigeration systems, the data on the specific systems and pumps and the design criteria is of great importance.

According to the European IPPC Directive 96/61/EC and its BAT leaflets canned motor pumps are considered as the “best available technology” for the conveyance of dangerous and ecologically harmful media.

The HERMETIC canned motor submersible pump provides the optimum solution for difficult installations. Essentially there are two different installations in the tank and in the vessel.

The CN/CNF/CNK...B modular system from HERMETIC increases usefulness to the customer. Lower service life costs, shorter delivery times and flexible conversion options are the most exceptional features of this new innovation.
