The Ratio:Matic Series of dual head dispensers and metering pumps provide precise dual channel fluid control for a broad range of process, production, laboratory and OEM applications.
The Ratio:Matic Series of dual head dispensers and metering pumps from Fluid Metering provide precise dual channel fluid control for a broad range of process, production, laboratory and OEM applications, including instrumentation in food, medical diagnostics, electronics, analytical chemistry and environmental monitoring.
Ratio:Matic pumps consist of two FMI pump heads direct coupled to a single variable speed drive.
Each pump head is independently adjustable, and a variety of pump head sizes can be used in combinations to achieve dispensing ratios from 1:1 up to 1000:1.
Ratio:Matic pumps are ideal for dual channel dispensing as low as 2ul per dispense, as well as proportional metering of two fluids into a single fluid stream up to 4 litre/min continuous flow.
Controlling two pump heads with a single drive motor and controller provides simplicity of control, as well as, significant cost savings.
The unique design of FMI's CeramPump uses one moving part, a rotating and reciprocating ceramic piston to accomplish both pumping and valve functions without valves.
The piston and mated liner are made of dimensionally stable, sapphire-hard ceramics which ensure long term, drift-free accuracy of 1% or better for millions of maintenance-free cycles.
The Ratio:Matic Series of pumps are available in AC, DC and stepper motor drive configurations.
Controllers are available ranging from simple process and quick start stepper control to programmable intelligent stepper drivers.
