Description

A range of automatic effluent water pumps for the removal of dishwasher, washing machine, bath shower or other waste is to be removed from the sump.

The NP400W is a 2” discharge pump. If a non-return valve is required, Newton recommends the V3 (a 2” free passage check valve). For increased duty in a twin pump system, separate discharge lines should be used. The NP750W is supplied with a one-way check valve and is suitable for 50 mm or 63 mm (via an adapter) discharge pipes. For increased duty in a twin pump system, separate discharge lines should be used.

The NP400W can be used with Newton Victron Power Inverter 12/1200/50 to give continual pumping during power outage, while the NP750W is compatible with the Newton Victron Power Inverter 12/3000/125.

Features and benefits:

  • Adjustable float arrangement that cannot be fouled by hardened soaps, effluent and grease.
  • Fluid temperature range: 0–40°C.
  • Semi-vortex pump design.
  • Single phase power supply.

Product Options

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.
