Default Spraying Systems nozzles

Not sure if these have been used before but:

from Autospeed:

The Spraying Systems Company of the US make amongst the world’s best water spray nozzles. They’ve got a huge range of nozzles, including those designed to atomise water.

The nozzles used in this application are in the Unijet small capacity range. These assemblies consist of a ¼ inch TT male body spray nozzle holder, a screen strainer incorporating a check valve, a spray tip and a tip retainer. All the components are top quality brass, with the nozzle tips using a stainless steel insert. The check valve stops the valve from dribbling when the pump is off (even if the nozzle is located below the level of the pump) and the strainer stops the tip being blocked by foreign material that might be contained in the water (however, see below for more on water filtration).
See table of nozzle sizes and flow, attached

Note: the factory nomenclature used for these tips can be confusing. Please check carefully before ordering.

See 3rd pic for suggested hose fittings.

If you need a larger flow, we suggest you use multiple nozzles.

The nozzle assembly (including strainer and cap) costs AUD$12 and the precision nozzles are $21 each.

It’s possible to get barbed hose fittings for both the nozzle and the pump and connect them together with high pressure hose held on with hose-clamps. However, we found in bench testing that time after time, the hose would blow-off either the pump or nozzle – we’re talking high pressure here!

You may be able to get away with running two hose-clamps at each end but to ensure reliability, we chose instead to use ‘push-in’ fittings for hard plastic hose. Good hydraulics and pneumatics hose suppliers have these fittings (and the hose).

The feed hose to the pump handles effectively no pressure and so pretty well any hose can be used.
The tips can be easily opened up with a screwdriver, making unclogging easy.
