NUODEAN High Pressure Diaphragm Pump Manufacturer offers 2:1 ratio pumps designed for applications where 120 PSI maximum pump operating pressure is insufficient to overcome system requirements.
The flow rate is almost the same of the equivalent size pump output, though a maximum discharge pressure of 200 PSI can be achieved with only 100 PSI air inlet pressure supplied.
The 2:1 discharge ratio is achieved by applying air pressure to the surface area of both diaphragms, doubling the discharge output.
