OEM Liquid Handling Pumps for Immunochemistry Analyzers
Immunochemistry analyzer developers need pumping systems that handle tiny analytical samples and much larger volumes for reagent movement, washing and rinsing. OEM integration succeeds when accuracy, flow, serviceability and electronic interfaces are assessed as one system.

Why dynamic range matters
A pump optimized only for small-volume sampling may struggle to prime or rinse efficiently. Conversely, a large-displacement unit may provide poor resolution at the low end. Differential Displacement™ is intended to achieve fine net displacement without giving up a high-flow operating mode.
The DRD Plexi approach
DRD describes its Plexi family as a long-service immunochemistry workhorse with integrated-valve configurations. Published DRD product materials describe variants up to 3.6 mL single-stroke volume and high flow for cleaning. These are model-specific statements and should be verified against current documentation before design freeze.
CV1dur and modular choices
The CV1dur 48S and 48T modules target different ranges and package constraints. Selection should consider the smallest and largest commanded volumes, acceptable bias and precision, duty cycle, footprint, motor driver integration and ease of service.
Questions to ask an OEM supplier
Request operating curves for relevant fluids, lifecycle data, seal and valve maintenance guidance, control-interface specifications, and a realistic validation plan. Confirm what comes with the module—motor, valve, board or software—and what the integrator is responsible for.
For a system-level decision, compare these principles against the performance data and technical documentation supplied for the particular DRD product. See the related DRD product and discuss the intended application with the engineering team.

Frequently asked questions
Why use dual-resolution pumping?
It can combine small-volume metering control with higher-flow operations needed elsewhere in an analyzer.
Is a catalog pump ready for any assay?
No. Chemical compatibility, accuracy, lifetime and the complete fluid path require application-specific qualification.
What integration information does DRD need?
Target volumes, fluid properties, flow rates, space, control requirements and anticipated duty cycle.
