May be the camera angle but that nozzle looks blocked, a blocked nozzle is guaranteed to drip

In fact, if you have any kind of pressure in the pipe expect it to drip.

To reduce the pressure you can adjust the pump, bleed some of the pump output back into the tank, fit a bigger nozzle.

To avoid the nozzle getting blocked you need a filter, there are all sorts of pond filters available for koi-keepers, I use a filter bag to strain all the gunge out before it gets back in the tank, empty it twice a year, icky job.

Swarf will try to block your return system. I usually stick a blow gun in the hose entrance to clear it and have a selection of old paint brushes to rearrange it on the bed. You will soon find something that works for you.
