The Newton NP400 is a high quality clean water pump ideally suited for the removal of ground water from basements and cellars. The unique vertical operation float switch ensures that the pump operates within its own footprint, removing the possibility of the float snagging during operation and allowing the pump to be used within smaller sumps. The vertical float switch is also very flexible, allowing the pump switching height to be adjusted, both in terms of the height between the ‘on’ and ‘off’ positions, as well as the height relative to the pump. The Newton NP400 is suitable for use with Newton Victron Power Inverter 12/1200/50 to give continual pumping even during power outage. The NP400 is supplied with a one way check valve and is suitable for use with 50 mm or 63 mm (via an adapter) rising mains. For increased duty in a twin pump system, separate discharge lines should be used. Newton NP Pumps are supplied with a 3-year manufacturers warranty or a 5-year back-to-base warranty if the pumps are serviced by a Newton approved service engineer. The Newton NP400 is sold in both manual and automatic versions and can be purchased as pump only, or as a key component in our packaged pumping systems.
