Yamada High Pressure Air Operated Diaphragm Pumps

Yamada® High Pressure Diaphragm Pumps offers 2:1 ratio pumps designed for applications where 100 PSI maximum pump operating pressure is insufficient to Yamada High Pressure Air Operated Diaphragm Pumpsovercome system requirements.

Yamada Brochure

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.

Key Advantages

  • No elaborate bypass required
  • No relief valves required
  • No complicated controls required
  • Great pressure retention (ability to hold pressure)
