Pumping Chamber / Tubing Section: Pressure Range 0-100 psi

Component Specifications

Definition

A critical component of fluid path assemblies consisting of a pumping chamber that creates pressure differentials and connected tubing sections that guide fluid flow. Engineered to maintain precise volumetric displacement, pressure consistency, and flow characteristics while minimizing turbulence, contamination, and pressure drops across the fluid path.

Working Principle

Utilizes positive displacement or dynamic pumping mechanisms where the chamber geometry creates pressure differentials through volume changes (diaphragm, piston, or peristaltic action), while tubing sections provide laminar flow paths with controlled cross-sectional areas to maintain flow rates and minimize energy losses.

Materials

Stainless steel (316L/304), PTFE, silicone, polyurethane, or engineered polymers with chemical resistance; medical-grade materials for sanitary applications; corrosion-resistant alloys for aggressive fluids.
