Precise, positive displacement metering
using 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.
