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.

Impact Group

The range of flow (typically measured in liters per minute) published in our catalog for a given nozzle. 
> _The catalog offers flow rates only for selected operating pressures so greater flow may be possible at pressures not shown in the catalog._

Liquid Flow Rate Range

Liquid Pressure

Many hydraulic spray nozzles include a numeric capacity size in the part number. Capacity size is often related to the flow rate of the nozzle at the rated spray pressure for that nozzle. For example, the capacity size for a 1/4HH10 FullJet® nozzle is “10”, which reflects a 3,78 lpm flow rate at 0,68 bar.

Capacity Size

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)_

Design Feature

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.

Model

We offer the _**“brand”**_ filter as a convenience because many Spraying Systems Co. nozzle brand names are recognized by customers around the world, such as VeeJet® flat spray nozzles and FullJet® full cone nozzles. Most of our nozzle brands are registered trademarks in the United States and in other countries around the world.
