Ultramicro Ceramic Valve-Free Metering Pump

Ultramicro Ceramic Valve-Free Metering Pump — Product Specification & Description

1. Product Overview

The Ultramicro Ceramic Valve-Free Metering Pump is a high-precision, pulse-free fluid dispensing system designed for sub-microliter to low-milliliter microfluidic applications. Featuring a valveless, single-plunger rotary design, this pump eliminates the clogging, wear, and backflow issues typical of traditional check valves. Engineered with ultra-hard, wear-resistant technical ceramics, it delivers exceptional repeatability, maintenance-free longevity, and high chemical inertness for ultra-precise liquid dosing.

2. Key Features & Advantages

• Valveless Precision Design: Combines synchronous rotation and axial reciprocating motion of a single ceramic plunger to direct fluid flow, eliminating internal check valves, sealing rings, and clogging risks.

• Ultramicro Volume Accuracy: Capable of dispensing microliter ($mutext{L}$) and nanoliter ($text{nL}$) volumes with dispensing accuracy within $pm0.5%$ and repeatability of $le0.3%$.

• Extreme Chemical & Corrosion Resistance: Fluid contact parts are crafted from sapphire-grade ceramic materials (high-purity zirconia or alumina) that resist strong acids, alkalis, organic solvents, and abrasive slurries.

• Pulse-Free & Constant Flow: High-precision motor integration ensures smooth, continuous, and pulse-free fluid transfer, ideal for delicate microfluidic and filling processes.

• Long Service Life: The near-zero clearance design between the ceramic piston and sleeve provides self-lubricating, wear-resistant operation across millions of cycles without maintenance.
