Milligram-Grade Integrated Ceramic Valveless Metering Pump

Milligram-Grade Integrated Ceramic Valveless Metering Pump — Product Specification & Description

1. Product Overview

The Milligram-Grade Integrated Ceramic Valveless Metering Pump is a compact, all-in-one liquid dispensing unit designed for high-precision micro-dosing applications. By embedding the drive motor, motion controller, and valveless ceramic pump head into a single integrated housing, this pump simplifies system architecture and saves critical space in automated equipment. Utilizing a valveless rotating and reciprocating plunger design, it delivers accurate, pulse-free, milligram-level dosing without internal check valves, dynamic seals, or risk of backflow.

2. Key Features & Advantages

• Compact All-In-One Integration: Combines the ceramic pump head, drive motor, and control electronics into a single plug-and-play module, minimizing wiring and footprint.

• Valveless Positive Displacement: Combines 360° rotation with axial displacement of the piston to direct fluid, eliminating valve clogging, jamming, and mechanical wear.

• Milligram-Level Accuracy: Capable of dispensing precise volumes down to 0.1 mg with volumetric accuracy of $le pm0.4%$ and high repeatability ($le 0.2%$).

• Wear-Resistant Ceramic Fluid Path: Sapphire-grade zirconia ($ZrO_2$) or alumina ($Al_2O_3$) plungers and sleeves provide tight clearance fits ($le 2mutext{m}$), self-lubrication, and zero particulate contamination.

• Chemical Immunity: Wetted components resist aggressive acids, alkalis, organic solvents, and sterile bio-fluids without corrosion or metal ion leaching.
