High Flow DC Circulation
The Johnson CO90 provides a stated flow of 100L/min at 0.1 bar, making it suitable for applications requiring substantial fluid circulation from a compact DC-powered pump.
Actual flow will vary depending on system pressure, pipework, fittings, fluid properties, electrical supply and installation conditions.
Continuous-Duty Operation
Designed for continuous-duty operation, the CO90 is suited to circulation applications where the pump may be required to operate for extended periods.
Correct installation, adequate electrical supply and unrestricted fluid flow are important for reliable pump operation.
Fresh Water, Salt Water & Glycol Compatibility
The CO90 can be used with fresh water, salt water and water/ethylene glycol mixtures containing up to 60% glycol, providing flexibility across marine, cooling and circulation applications.
Fluid compatibility should always be confirmed where additives or chemicals other than water and ethylene glycol are present.

CO90 Pump Performance
The performance information below can be used when assessing the CO90 for your installation.
Installation & Operation
Select the correct 12V or 24V model to match the electrical system and ensure wiring, circuit protection and connections are appropriately sized for the installation.
As a centrifugal circulation pump, the CO90 should be installed so that it receives an adequate fluid supply. Do not operate the pump dry. Running without fluid can damage the mechanical seal and other pump components.
Ensure hoses and fittings are correctly sized and securely installed, and avoid unnecessary restrictions in the suction and discharge plumbing that may reduce pump performance.
