Fuel pump filter: protect the pump and burner

The fuel pump filter is placed on the power line, upstream of the burner. It retains particles and deposits present in the fuel (usually with filtration thresholds from 50 to 100 μm), stabilizes the pressure and avoids premature fouling of the pump and the nozzle. Essential to preserve the performance of the boiler, it completes the action of the Internal fuel pump sieve.

When to replace the filter?

Difficult starts, a pressure drop, recurring defusing or a dirty bowl indicate a saturated filter. Replacing the cartridge is recommended during annual heating maintenance, and more frequently in case of unclean oil or prolonged inactivity. A clean filter limits overconsumption and promotes stable combustion.

Which filter choose?

Depending on your installation, opt for a door-filter With transparent bowl (fast visual control), a cartridge Felt or synthetic adapted to the desired filtration finesse, and, if necessary, useful functions (purge, check valve). Make sure the hydraulic compatibility (flow, viscosity) and connections (3/8 '', 1/2 ''). Our line filters are suitable for facilities equipped with pumps Suntec and Danfoss, and integrate with most domestic burners.
