Precise, Positive Displacement with Double-Acting Cylinders

The 8900 Proportioner uses fluid inlet pressure to continuously reciprocate two connected cylinders. This fluid pressure is usually provided by two pumps which supply consistent pressure to the proportioner cylinders. As the major volume cylinder (base) and minor volume cylinder (catalyst) reciprocate, they positively displace the two material components on ratio to the outlet ports. Specially-sized hoses connect the proportioner to a choice of mixers to ensure ratio accuracy. Static mixers are incorporated into the system to deliver a homogeneous mix of base and catalyst.
