TED are powered by Honda 4-stroke, recoil start, petrol engines. They have the Oil Alert engine protection system fitted to prevent damage from inadequate lubrication during use with low oil, or while at an angle. All models have easy-carry frames, rubber feet (for engine noise and vibration absorption) and wing nuts for easy chamber access. Capable of pumping large volumes of water that contains sand, silt and suspended large solids, they are good for site drainage, land drainage, liquid waste removal, sewage and flood defence.
