Fresenius do a syringe pump for paediatric enteral feeds. It takes reverse luer syringes (female luer on the syringe) as well as the normal spigot feed syringes. It has variable pressure alarms, I do not know what levels they are but there is a fact sheet on their site.
Have a look at the Pilot Enteral on the Fresenius site.
