Form 

 Balanced pressure proportioning device is mainly composed of foam tank, foam pump, power source, balancing valve, proportioner, with the pressure relief valve, composed of 
 The foam pump gear pump, rotor pump, foam pump, turbine, electric motor or diesel engine three drive mode. 
 Foam tank capacity can be set according to the practical application of engineering.
