cleaning spray-147

The principle of a trigger pump is a small engine with a piston in a cylinder which pumps liquid through a dip tube in the cylinder and, using the pressure created by squeezing the handle, the liquid is forced through the nozzle base into the nozzle itself. The nozzle can emit a fine mist, a spray or a jet and, with a special insert, it can also emit foam.The trigger pump contains several injection moulded parts assembled on a special fully automatic assembly machine.
The latest polymer materials which the triggers are made of are highly compatible with a wide range of liquids.There are 2 functions of the trigger pump: direct compression and pre-compression.

1. Direct compression: The liquid goes directly from the dip tube inside the cylinder and, by squeezing the handle travels via the nozzle base through the nozzle itself. This function is common for most simple liquids like surface cleaners, de-icers, and many more.
   
2. Pre-compression: The benefit of this type of function is that it gives the trigger a full spray without liquid fall off, or any large droplets of the liquid forming, because of a special valve inserted in the chamber of the trigger.  
   

The consumer triggers sprayers are available in standard neck sizes such as 28-400, 28-410 and RD28 and lock cap
