Fluid Metering Inc. Duplex Pumps Are Valveless
- Published: April 29, 2013
SOMERSET, NJ | Fluid Metering Inc. (FMI) offers OEM Duplex Metering Pumps that consist of two company’s valveless pump heads directly coupled to a single variable 
stepper motor drive. The displacement of 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 500:1.
STH and STQ Duplex metering pumps, recommended for diluting and proportional fluid control with ±1% precision for medical and analytical Instrumentation, feature company’s patented CeramPump valveless piston pumping technology and are the valveless-syringe alternative to conventional syringe pumps. The CeramPump has only one moving part in the fluid path—a sapphire-hard ceramic piston—which is said to accomplish both pumping and valving functions, without valves.
