Dual head dispensing and metering pumps offer dispensing as low as 2ul and dual channel dispensing ratios from 1 to 1000:1
The Ratiomatic series of dual head dispensers and metering pumps from Fluid Metering are said to provide precise dual channel fluid control for a broad range of process, production, laboratory, and OEM equipment.
Applications include instrumentation in food, medical diagnostics, electronics, analytical chemistry, and environmental monitoring.
Ratiomatic 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.
Ratiomatic pumps are said to be 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 four4 litres/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 design of FMI's CeramPump utilises one moving part, a rotating and reciprocating ceramic piston to accomplish both pumping and valving 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 Ratiomatic 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.
