Maintenance – hydrocyclone filters

Maintenance for hydrocylone filters is quite straightforward as there are no moving parts. In fact, the maintenance is more the actual manual cleaning of the filter since there is no back-flush mechanism.

  • Open the drain valve periodically and remove sand collected in the sand collection chamber. Do not allow the sand to build to more than 1/3 of the tank.

  • Make periodic checks for leaks and to ensure overall good condition.

  • Remember that hydrocyclones require a specific flow range to operate. Ensure this flow rate and head loss is still being achieved. If you don’t have the minimum head loss specified, the filter is not providing filtration.
