Yamada® High Pressure Diaphragm Pumps are designed for applications that require higher pump operating pressures than what is typically available from standard pumps. These pumps have a 2:1 ratio, meaning that for every unit of air pressure supplied to the pump, it will produce twice the output pressure.
For instance, if the air inlet pressure supplied to the pump is 100 PSI, it will generate a maximum discharge pressure of 200 PSI, allowing it to overcome the system requirements of many applications. This capability makes these pumps ideal for applications that involve pumping high-viscosity fluids or transferring materials over long distances.
The 2:1 discharge ratio of Yamada® High Pressure Diaphragm Pumps is achieved by applying air pressure to the surface area of both diaphragms, while only utilizing one working liquid chamber, thus doubling the pressure on the liquid. When air pressure is applied to one side of the diaphragm, it moves in one direction, displacing the fluid in the pump chamber. When air pressure is then applied to the other side of the diaphragm, it moves in the opposite direction, re-filling the liquid chamber that was just discharged. This process effectively doubles the output pressure of the pump, allowing it to handle a broader range of applications.
One important thing to note about Yamada® High Pressure Diaphragm Pumps is that while they can produce higher discharge pressures, the flow rate is roughly half of what an equivalent size pump would deliver. This is because the pump chamber volume is reduced by half due to the 2:1 ratio, resulting in a lower flow rate. However, the ability to achieve higher discharge pressures with a lower air inlet pressure can make these pumps a cost-effective option for some applications.
In summary, Yamada® High Pressure Diaphragm Pumps are designed to handle demanding applications that require higher pump operating pressures. Their 2:1 discharge ratio, achieved by applying air pressure to both diaphragms, doubles the output pressure and volume of the pump. While the flow rate may be lower than an equivalent size pump, the ability to achieve higher discharge pressures with lower air inlet pressures makes these pumps a reliable and cost-effective option for many industrial applications.
