Cobalt 600 Filterpumps

Cobalt submersible filterpumps are low to medium head industrial use centrifugal pumps. These robust filterpumps benefit from a cast iron upper cover, a strengthened AIS1304SS motor case, chrome steel impeller and a built-in stainless steel self-cleaning intake which protects against blocking.

Cobalt filterpumps combine pumping and screening up to a maximum of 108 m3/hr, the smallest CKC31.5-400 model has a maximum head of 15 m, and the largest CKC45.5-600 model 30 m.

These filterpumps are built for heavy-duty industrial. Typical uses for Cobalt filterpumps are:

• Mining industry drainage
• Irrigation from lakes, ponds or rivers for irrigation
• Pumping stormwater and floodwater
• De-Watering Slurry Lagoons and Dirty Water Irrigation
• Screening industrial process water for re-use or disposal

These filterpumps are ideal for screening and pumping raw water, clean or dirty water irrigation, pumping in harsh environments, and general heavy industrial uses. 

The Cobalt filterpumps weigh up to 150 kg, lifting gear is required to move them. These filterpumps can be suspended in tanks, sumps or ponds or from buoys, or raised and lowered on a guide-rail system.

For best performance, make sure that there is good clearance around the filterpump mesh so that back-washed debris can disperse, and that the filterpump is above any silt or sludge that may accumulate.

Rotorflush Filters Ltd is happy to advise and comment on siting and installation.

There is no such thing as an entirely maintenance free filter, but Cobalt filterpumps, in keeping with all Rotorflush filtration products, are designed for low maintenance hassle-free use.  

The stainless mesh can be cleaned with a pressure washer. There is a trade-off between mesh size and maintenance - how often depends on your mesh size and what you are filtering.

As a minimum we recommend the following:

• 315 micron mesh should be cleaned every 5000 hours of use
• Coarse mesh that is 1 mm or bigger should be inspected and cleaned every 6 - 12 months

Full maintenance guidelines can be found in the instruction manual available from the download link above.

All our products are guaranteed for a year. However, as a condition of our guarantee, and to protect against dry-running, we recommend the use of a starter panel or control panel capable of cos phi load monitoring when running three-phase filterpumps.
