CL1 Pump Assembly Upgrade Kit [2-600-037]

One-time field upgrade conversion kit to replace discontinued pumps (DOD #870328) in existing CL1 systems. See the Technical Note for full details.

Do NOT order for pump replacement on units previously upgraded/converted or manufactured after January 2025. 

The CL1 Pump Assembly Upgrade Kit (2025 Version) provides the necessary components to convert existing CL1 units to accept the newer replacement pumps. The kit assembly includes two new pumps (left and right), supporting hardware and a MicroSD card. Once upgraded/converted, the newer pump assembly (#2-600-038-A) should be ordered as the ongoing replacement. 

** NOTE: HMI firmware updates can only be performed by the DOD Technical Service Center. Software upgrades in the field are possible once firmware requirements are met. 

CL1 units can also be sent to the DOD Technical Service Center for conversion. Click here to receive an estimate and return authorization number after completing the form. Separate kits are available for systems that include the self-cleaning/black flush feature and CL2 systems. Contact our Technical Services department for details and assistance.
