Nauti Range Submersible Pumps

From £2,120.00 (GBP)

Our Nauti Range Submersible Pumps with self-cleaning filters have a maximum output of 220 litres per minute (14 m3 per hour) and can pump up to 10 bar. They are powerful high-head pumps with built-in self-cleaning intake filters.

Pumping and filtration are combined and the filter's self-cleaning mechanism protects the pump and other equipment from blockage. It is ideal for high pressure pumping of water contaminated with suspended solids. The Nauti Range pumps are a favourite of the water industry and are used for pumping and filtering final effluent for wash water.

These self-cleaning filterpumps are also excellent for keeping fountain and irrigation nozzles clear from blocking.

*single phase only

 

Nauti Range submersible pumps are available in single phase with or without a float switch and three phase.

NB: It is very important that three phase motor filterpumps are connected to their power source correctly, to ensure that the pump motor runs in the right direction. When pumps run backwards they are inefficient and the motor may be damaged.  To see how to test that the pump is wired correctly watch this video.

Please note that we strongly recommend the use of Control Panels and / or a Din Rail mounted Cos Phi Load Monitor with all 3 phase models to prevent damage to pumps.

Installing adequate load monitoring is a condition of our guarantee for these products.
