Series R Ceramic Micro- Metering Pump

Series R Ceramic Micro-Metering Pump — Product Specification & Description

1. Product Overview

The Series R Ceramic Micro-Metering Pump is an ultra-precise positive-displacement pump specifically designed for low-volume micro-fluidic dosing, dispensing, and filling. Utilizing an advanced rotating-reciprocating ceramic piston design, the Series R series eliminates dynamic seals, internal check valves, and spring components to prevent valve lag, backflow, and fluid clogging. Crafted from high-density, wear-resistant technical ceramics, it provides exceptional volumetric accuracy, long-term stability, and chemical immunity for sensitive medical, diagnostic, and industrial applications.

2. Key Features & Advantages

• Valveless Positive-Displacement Architecture: Combines continuous $360^circ$ rotation with precise axial stroke displacement to govern fluid intake and output, completely eliminating check valve sticking and pressure spikes.

• Micro-Liter Precision & Repeatability: Achieves dispense volumes down to sub-microliter range with volumetric accuracy within $le pm0.5%$ and high repeatability ($le 0.2%$).

• Sapphire-Grade Ceramic Fluid Path: Features high-purity Zirconia ($ZrO_2$) or Alumina ($Al_2O_3$) pistons and sleeves with near-zero clearance fits ($le 2,mutext{m}$), ensuring self-lubrication, zero particulate shedding, and minimal wear across millions of cycles.

• Universal Chemical Compatibility: Inert ceramic contact components resist concentrated acids, strong alkalis, organic solvents, and sterile biological reagents without metal ion leaching or material degradation.

• Maintenance-Free Longevity: Eliminates dynamic elastomeric seals and check valves, dramatically lowering maintenance downtime and operational costs.
