The Ama-Drainer N 301 SE/NE is a single phase submersible drainage pump with a 0.18kW motor. Capable of operating at an immersion depth of 2m, the KSB Ama-Drainer N is a submersible pump for draining wastewater. All models can handle solids up to 10mm in diameter. The Ama-Drainer 358 model is capable of handling long fibres and stringy material and solids up to 35mm in diameter. The pumps are all fitted with a magnetic float switch allowing automatic operation where the pump is installed - when it detects liquid to be pumped it will automatically switch on and automatically switch off when the liquid has been pumped. The plastic casing means these pumps are lightweight and easy to install.
