The NEW Yamada 2:1 high pressure pump was specifically designed for applications where 100 PSI maximum pump operating pressure is not enough to overcome system requirements. The flow rate is roughly half of the same size pump output, though a discharge pressure of 200 PSI can be achieved with only 100 PSI air inlet pressure supplied. The 2:1 discharge pressure ratio is achieved by utilizing twice the surface area (driving both diaphragms) to double the output.
No elaborate bypass required, No relief valves required, No complicated controls required, Great pressure retention (ability to hold pressure), 3/4” through 3” port sizes available. 316 Stainless Steel, Cast Iron, and Aluminum wetted materials.
