Rotorflush Cobalt 600AR filterpumps are industrial filterpumps, suitable for mining, quarrying and heavy industrial and agricultural applications.
Their 600mm 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 1800 litres a minute and provide the same low maintenance and efficient intake screening of all our submersible filterpumps.
The Cobalt range 600AR 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 600AR Submersible Pumps with Built-in Self-cleaning Intake Screens
The Cobalt range is a range of industrial low to medium pressure self-cleaning submersible filterpumps offering up to 1800 litres per minute (108 m3 / hr). The Cobalt Range 600AR filterpumps are very robust, they have a cast iron upper cover, a strengthened AIS1304SS motor case and a chrome steel impeller. The stainless steel self-cleaning intake lets you combine pumping and screening from source without the screen or pump blocking. They are ideal for screening and moving large volumes of dirty water.
Cobalt Range 600AR filterpumps have self-cleaning intakes that prevent debris entering the pump and keep debris off the filter screen. They can be fitted with a range of mesh sizes:
315 micron stainless steel sintered filter mesh
1mm or 2mm woven stainless steel mesh
3mm perforated steel mesh.
The Cobalt range filterpumps are suitable for heavy duty use and can be manufactured with 316 stainless steel self-cleaning intakes made with 316 stainless steel. All our filter mesh is 316 stainless steel. Stainless steel mesh is ideal for more challenging environments.

Powerful Pumping and Screening Combined
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.

Rotorflush filterpumps work best with good clearance all around the self-cleaning intake filter.
We can fit stands to suit.
Please Note: Our filters are designed for use in dirty water or liquids with a viscosity close to that of water. Our filters and filterpumps are NOT suitable for use in raw sewage or any other dirty water which contains oils or fat.
