Innovative facts to know about QUANTUM series


The construction of QUANTUM pumps also included free-fastening diaphragms. This allows easy maintenance, more safety when pumping aggressive liquids and reduced air consumption. 


It is possible to disassemble the valves for maintenance without disassembling the entire pump already installed on the plant. 


AODD pumps are usually suffering from ice formation in the distribution system. Our engineers propose an additional gasket located nearby the distribution system for moving the exhausted air, at low temperature, towards the discharge chamber. Thanks to this gasket, QUANTUM pumps are not sensible to humidity in the air so there is no influence on the efficiency. 


A new simple, compact, and highly efficient air distribution system was conceived. It is equipped with an air capacity regulator - without interfering with the pressure used in the control units. Thanks to the quick discharge valve, a considerable air consumption reduction is noted (up to -30%), which also permits avoiding ice formation inside the distribution system. QUANTUM pumps can, therefore, operate in any work condition. 


QUANTUM's DDQ 1" and DDQ 1 1/2" models are equipped with internal pipes to totally remove the liquid from the pump: an efficient and accurate solution for improving the operative and functional characteristics of the pump.
