2:1 High Pressure Pumps
The Yamada 2:1 high pressure pumps are designed for applications when a maximum 7 Bar 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 13 Bar can be achieved with only 7 Bar 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.
Available wet materials: Aluminum, Cast Iron and 316 Stainless Steel and the available diaphragms are: CR, NBR, EPDM and FPM. Capacity from 1 – 380 liter per minute. Discharge pressure till max 13Bar and the pumps can handle solids up til 10 mm.
- 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
Note: 2:1 high pressure pupmps are considered simplex pumps which will increase pulsation during operation. Consult Yamada Europe for proper pulsation dampener selection.
