he Fluid Powered Proportioning Pump FPP
series, developed by Fluid-o-Tech, is designed
to mix two different fluids with a high degree
of accuracy. The pump operates thanks to the
energy stored in any pressurized fluid, which
gives power to the unit. The mixing ratio,
determined by the dimensions of the two
chambers, is constant regardless of the flow rate
ａnd pressure requested by the application.
The food grade materials used in the pump,
have a high degree of compatibility.
