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 CP 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.

Please note that this product is for pumping clean water only.

Newton pumps should be serviced by trained and qualified pump engineers only. It is recommended that pumps are serviced within 6 months of installation and then at service engineer's discretion, but with at least one inspection or service every 12 months - consult manufacturer for further details.

Description

The Newton CP250, CP400 and CP750 are 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 pumps are suitable for use with Newton power converters of 1200 W (CP250 and CP400) or 3000 W (CP750) to give continual pumping even when the power is out.

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:

  • Thermal overload protection against motor burnout.
  • Non-clogging vortex impeller.
  • Protection against motor burnouts due to a locked 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 ready to receive pressure rated pipe. Also supplied with one-way-valves, which are designed to screw directly into the pump body.
  • One year manufacturer warranty. Three year warranty available if serviced at regular intervals by approved engineers.
