Blasting guns are the switching point between the high pressure pump unit and the array of nozzles and blasting tools available: Various switching and control mechanisms are available:

The new handgrip generation
This new handgrip design enables operation of blasting guns with considerably less force than normal which is much safer and extends blasting times. A lever mechanism literally allows the trigger to be held by your little finger.

With electrical control signal
A proximity switch sends an electric signal via a cable to the pump bypass control.

Mechanical bypass (dump) gun
Releasing the trigger causes the gun bypass valve to open emitting the water via a hose without pressure.

With mechanical dry shut off valve
Operating the trigger opens the valve allowing high pressure water to flow. Releasing the trigger closes the valve shutting off the flow. Maximum 1000 bar.

The gun is operated by a transponder with the signal to the pump bypass control transmitted via 4 wire technology.
