High-efficiency submersible motor pumps meet ATEX standards
From June 2025 the KSB Group’s new high-efficiency AmaRex Pro submersible motor pumps will also be available as an explosion-proof version. These pumps fulfil the stringent European Directives ATEX 2014/34/EU and ATEX 1999/92/EC. They are suitable for being operated in hazardous zones classified as Zone 1.
To prevent ignition sources such as sparks or hot surfaces, the engineers designed AmaRex Pro in such a way that no flames or sparks can be caused outside the pump casing. In addition, the pump set is protected against the generation of internal sparks.
The areas of the high-efficiency IE5 motors and the electronic control units are fitted with overheating protection equipment. Excessive heating will trigger an alarm and interrupt the power supply to the pump set.
The manufacturing process of the hydraulically highly efficient pumps is checked several times a year by an ATEX inspector. This is how the manufacturer ensures that the pumps are of a high quality and produced in compliance with the ATEX requirements.
Given the possibility that hydrogen sulphide H2S and methane, both of which are highly flammable gases, may form in waste water, Germany and some other countries classify waste water pumping stations as a potentially explosive atmosphere. These gases may collect in the waste water pipes and collecting tanks. Contact of these gases with a source of ignition may result in an explosion.
