As far as I am aware they have a good reputation for taking care of all travellers whether needing medical assistance or not ? Here are a couple of extracts from their fact sheets which show at least two valid reasons for their concerns and interest.
Generally, medical conditions should not inhibit you from flying. However, due to a cabin pressure equivalent to an atmospheric pressure at 5,000 to 7,000 feet altitude, special precautions are sometimes required. For more information, please also read the details below.......(see full info)
Medical Equipment
For flight safety reasons, Singapore Airlines will only accept electrical/electronics medical equipment for carriage upon approval. This is to ensure that the equipment does not interfere with the aircraft’s navigation and communication systems. Crew may direct that it be turned off if it is suspected to cause interference to the aircraft's systems.
Please inform us at the time of booking if you are travelling with medical equipment and obtain the necessary medical clearance unless indicated otherwise.
All self-powered medical devices are not accepted with exception of the following:
Portable Hearing aids
Heart pacemakers
Nebulizers
Continuous Positive Air Pressure (CPAP) machine (please see below for more details)
Portable Oxygen Concentrator (please see below for more details)
So I think that they are just making sure that the pump does not interfere with the planes systems and neither will it be damaged by the cabin pressure - seems fair enough to me ??
