Cobalt Range 400AR Submersible Pumps

From £7,912.00

Rotorflush Cobalt 400AR filterpumps are industrial filterpumps, suitable for mining, quarrying and heavy industrial applications.

Their 400mm diameter stainless steel self-cleaning intake screen can be manufactured from 304 or 316 stainless steel.  The powerful three phase motors have a thermal cutout  and the intake screens are available in a range of mesh sizes.

These filter pumps offer fine or coarse filtration while pumping up to 1000 litres a minute and provide the same low maintenance and efficient intake screening of all our submersible filterpumps.

The Cobalt range of filterpumps use Rotorflush's unique self-cleaning intake filter technology. They deliver an uninterrupted supply of water while a continuous backwash keeps the intake, pump and other downstream equipment blockage free.

Models & Specification

Cobalt Range 400AR Submersible Pumps with Built-in Self-cleaning Intake Screens – 1000 litres minute

The Cobalt Range 400AR filterpumps are a range of industrial low to medium pressure submersible pumps with integral self-cleaning suction intake screens.  These filterpumps benefit from a cast iron upper cover, a strengthened AIS1304SS motor case and a 400mm stainless steel self-cleaning intake, capable of delivering up to 1000 litres minute of filtered water.  They combine pumping and screening and are ideal for use in difficult and dirty water.

Cobalt Range 400AR filterpumps have self-cleaning intakes to prevent debris entering the pump and keep debris off the filter screen. They can be fitted with a range of mesh sizes:

  • 115 or 300 micron nylon filter mesh
  • 100 or 315 micron stainless steel sintered filter mesh
  • 1mm or 2mm woven stainless steel mesh
  • 3mm perforated steel mesh.

 

Stainless steel mesh is ideal for more challenging environments. Cobalt 400AR filterpumps are suitable for heavy duty use and can also be fitted with 316 stainless steel self-cleaning intakes.

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.
