The volume of liquid passing through a nozzle (also called the nozzle’s capacity) is typically measured in liters per minute. Flow rate is affected by liquid pressure and other factors, including the specific gravity and viscosity of the liquid being sprayed.

GunJet spray guns are available for a wide range of operating pressures. The maximum operating pressure for any Low Pressure GunJet spray gun is 17 bar. The maximum operating pressure for any Medium Pressure GunJet spray gun is 69 bar. The maximum operating pressure for any High Pressure GunJet spray gun is 275 bar. Be sure to check the specifications for each GunJet spray gun carefully and follow all safety guidelines.

Liquid Pressure

Spray nozzles are manufactured from a wide variety of materials that have been determined to meet the usual requirements of the applications most commonly associated with that type of nozzle. Standard materials include brass, steel, various stainless steels, hardened stainless steels, many plastics and various carbides. Spray nozzles can also be supplied in other materials upon special request. Materials of construction affect nozzle wear life and resistance to corrosion and abrasion.

Materials

Our products are grouped into these primary product types:
- Nozzle - Body _(a nozzle body without a spray tip)_
- Tip _(a spray tip without a nozzle body)_
- Assembly _(a complete nozzle assembly including both a nozzle body and a spray tip)_

Product Type

Specific gravity is the ratio of the density of a fluid compared to the density of water. It must be considered to properly calculate flow rate. 

 **Alternatively**, if you don't know the specific gravity you may select the **Liquid Type** from a list of commonly-sprayed liquids and temperatures.

### Liquid Type

 The type of liquid sprayed and its temperature affects the specific gravity of the liquid and in turn affects the flow rate. The default liquid is water, with a specific gravity of 1.

Specific Gravity

The angle of the spray pattern as it emerges from the nozzle orifice, measured in degrees. Narrower spray angles provide less coverage of the sprayed surface. Wider spray angles provide greater coverage of the sprayed surface. Solid stream nozzles have a 0° spray angle.

Spray Angle

Most nozzles are available with NPT or BSPT connections. Other threaded connections are available on select nozzles and additional connection types, such as flange and quick-connect, are also common. Some nozzles are also available with sanitary connections.
