Yamada® High Pressure Diaphragm Pumps are 2:1 ratio pumps designed for applications where 100 PSI maximum pump operating pressure is insufficient to overcome system requirements.
The flow rate is roughly half 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.
