CP Pumps

Ideally suited for the removal of ground water from basements and cellars. Sold in manual and automatic versions and can be purchased as pumps only, or as a key component in our packaged pumping systems. 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 highly adjustable, allowing the pump switching height to be adjusted between the ‘on’ and ‘off’ positions, as well as the height relative to the pump. The Newton CP Pumps are suitable for use with Newton Victron Power Inverters to give continual pumping even during power outage.

The Newton CP series pumps are sold in both manual and automatic versions and can be purchased as pumps only, or as a key component in our packaged pumping systems.

  • 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 impeller 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
  • Continued pumping even during power cuts when used with Newton Power Inverters

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

Newton CP Pumps are supplied with a 1-year manufacturers warranty or a 3-year back-to-base warranty if the pumps are serviced by a Newton approved service engineer.
