ERMA FIRST FIT flow loss during backwashing: order targeted service
Updated
Sea Clean can investigate FIT flow loss during filter backwashing and supply the identified filter, actuator or instrument parts. Include pressure and flow records from the cleaning event so the repair targets the actual restriction.
Key takeaways
- Filter and actuator labels
- Pressure/flow trends through backwash
- Discharge route
- Available operating window

Capture the full cleaning event
ERMA FIRST describes FIT as filtration followed by electrolysis. Record flow and inlet/outlet pressure before, during and after backwashing, together with valve commands and alarm timing. A high differential pressure and an incomplete cleaning cycle point to different work than a low available inlet pressure.
Check the installed filter and discharge path
Use the actual filter nameplate, element and actuator identities rather than a generic FIT spare list. Include the backwash discharge arrangement and relevant isolation valves. A service package can then cover the cleaning mechanism, pressure measurement and discharge restrictions as well as the screen condition.
Agree the operating evidence
Request a complete cleaning cycle, leakage inspection and pressure/flow observations after the work. Sea Clean can quote parts and attendance together, with a report identifying the conditions under which the filter was tested. Record remaining water-quality constraints separately from repaired equipment defects.
Illustrative procurement scenario
The filter recovers after manual cleaning but loses flow again during automatic backwashing. The order includes actuator sequence and discharge-path checks rather than repeated screen cleaning alone.
