High Pressure

Yamada® High Pressure Pumps

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.


Key Advantages

  • 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
  • EPDM, Neoprene, Buna N, Viton®, Santoprene®, and Hytrel® elastomers
  • Capacities from 1 to 100 GPM
  • Discharge pressure to 180PSI
  • Can handle solids as large as <13/32” (10mm)


  • Charging filter press
  • High head requirements
  • High viscosity fluids
  • Solids laden slurries
