CHEMICAL PUMPING SYSTEM
The chemical is drawn from the chemical container
through a strainer into the flow meter. The flow
meter indicates the rate of chemical flow.
The chemical then flows through a check valve into
a pulse-powered chemical pump.
Next, the chemical pump injects the chemical
through a check valve to the 3-way selector valve on
the control panel. This valve may turn the chemical
flow ON, OFF, or PRIME.
The chemical then flows through a metering valve to
the solution outlet. This valve controls the rate of
flow of chemical injection into the solution, which is
indicated on the flow meter.
