Cobalt Range 400AR Submersible Pumps
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.

Cobalt Range submersible pumps have three phase motors and are fitted with self-cleaning suction intake screens.
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.
