Newton NP Clean Water Pumps
A range of clean water pumps.
Application
Primarily designed to be used with Newton sump systems for the removal of ground water collected by Newton System 500 basement waterproofing system. Newton NP pumps can also be used for the removal of water from:
- Flooded basements and cellars;
- Light-wells;
- Surface drainage collection vessels;
- Reservoirs and water holding vessels.
Description
A range of high-quality clean water pumps, suitable for the removal of ground water from basements and cellars. The unique vertical operation float switch ensures that the pumps operate within their footprint, removing the possibility of the float snagging during operation and allowing the pumps 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, while the Newton NP750 can be used with the Newton Victron Power Inverter 12/3000/125.
Supplied in both manual and automatic versions and can be purchased as pumps only, or as a key component in Newton packaged pumping systems.
Features and benefits:
- Suitable for use with 50 mm or 63 mm pressure rated pipe and fittings.
- Thermal overload protection against motor burnout.
- Non-clogging vortex impeller.
- Double mechanical seals ensure increased durability against particle abrasion and wear.
- Anti-airlock impellor housing ensures that the pump is able to remove trapped air even when the sump was previously dry.
- High performance and efficiency even with a low current.
- Unique vertical float allows complete adjustment of the start and stop heights.
- Provides continued pumping even during power cuts when used with Newton Power Converters.
- Supplied with pipe fittings. Also supplied with one-way-valves, which are designed to screw directly into the pump body.
