gULP installed as a Pump fed system

gULP can be installed as a pump fed gravity return filtration system. In such instances again a low power pump can be used to simply lift water from a settlement chamber directly into the mechanical stage of your gULP installation. Water then simply overflows into the second stage of your gULP filter system.

Once the biologically treated water is ready to leave the filter it can simply discharge from the upper 110mm outlet moulded onto gULP. If you prefer to run gULP as full as possible a rubber flange can be easily installed on any of the four flat surfaces that gULP offers you.

Gravity return systems work well on Koi ponds and are suitable for installations where digging or installing a gravity fed system is not practical or possible.
