Newton SP750 Cutter Sewage Pump
Application

Suitable for use on:

  • The removal of sewage and waste water from suitably manufactured sewage vessels;
  • Standard pumps supplied within Newton Trojan sewage lifting stations.

Can also be supplied as the pump option for Newton 1 m diameter sewage systems.

Description

A high quality sewage pump incorporating a tungsten carbide tipped cutting impeller that rotates against a serrated suction cover in order to cut solid waste before pumping, resulting in a much lower risk of blockage than similar sized vortex impeller pumps.

The SP750 Cutter has a cast iron base and stainless steel body, and is suitable for the removal of sewage and effluent waste within small to medium sized sewage chambers, and is especially suited for use within sewage lifting stations such as the Newton Trojan Pumping System - consult manufacturer for details.


Supplied in single phase (230 V 50 Hz) only, the product is available as both freestanding or for guide rail mounting when supplied with the optional auto-coupling set (1000 mm diameter chambers only). Switching options are also available with the SP750, which can be purchased with a fitted float switch for auto operation or without a float for control by a compatible Newton pump control panel. They are supplied with 10 metres of heavy duty rubber power cable.


Features and benefits:

  • Cutter impeller cuts through the waste, resulting in less blockages.
  • Provides protection against motor burnouts due to a locked impeller.
  • Double mechanical seals ensure increased durability against particle abrasion and wear.
  • High performance with low current and high efficiency.
  • Auto and manual versions are available.
  • Freestanding and guiderail mounted options.
  • Supplied with a one-year manufacturer’s warranty from the proven date of installation or the date of purchase. Three year warranty if serviced under a service contract.

System:

  • 63 mm pressure rated pipework and fittings.
  • Sewage panel single pump.
  • Sewage panel twin pump.


Power converter:

The Victron Inverter/ Charger units draw 12 V power from a single or a bank of 12 V batteries which is inverted into clean, pure sine wave, 230 V power to ensure that the Newton Pump continues to operate even during a power outage.


Control panel:

The panel features interface for use with Newton battery back-up and telemetry systems as well as connections to whole house alarm and monitoring systems. The control panel PCB is split with two separate circuits, ensuring that pumping will continue even if one of the control circuits should fail.
