Newton NP400W

This pump has been specifically placed within the Newton pumping range for when dishwasher, washing machine or bath / shower waste is to be removed from the sump. The NP400W is an automatic pump with a specially designed adjustable float arrangement that cannot be fouled by hardened soaps etc.

The NP400W is a 2” discharge pump. If a non-return valve is required we recommend the V3 (a 2” free passage check valve). For increased duty in a twin pump system, separate discharge lines should be used. The pump is sold as pump only, or as a key component in our Newton Trojan packaged pump system.

The NP400W can be used with a Newton Victron Power Inverter 12/1200/50 to give continual pumping even when the power is out.
