Ceramic Valveless Metering Pump

Ceramic Valveless Metering Pump — Product Specification & Description

1. Product Overview

The Ceramic Valveless Metering Pump is a positive-displacement dispensing system engineered for ultra-precise liquid transfer and micro-filling. Utilizing a single rotating and reciprocating ceramic plunger, this pump eliminates internal check valves, elastomeric seals, and dynamic packings. Designed with sapphire-hard technical ceramics, it delivers zero-maintenance operation, pulse-free flow, and exceptional resistance to aggressive chemicals and abrasive slurries.

2. Key Features & Advantages

• Valveless Positive Displacement: Combines 360° plunger rotation with axial displacement to direct fluid inlet and outlet ports, eliminating check valve clogging, lagging, and leakage.

• Extreme Accuracy & Repeatability: Provides precise volumetric dosing with dispensing accuracy of $le pm0.5%$ and high repeatability ($le 0.2%$).

• Wear-Resistant Ceramic Fluid Path: High-purity zirconia ($ZrO_2$) or alumina ($Al_2O_3$) pistons and sleeves feature near-zero clearance fits ($le 2mutext{m}$), offering self-lubricating, non-galling performance over millions of cycles.

• Broad Chemical Compatibility: Chemically inert ceramic wetted parts resist strong acids, harsh alkalis, organic solvents, and sterile biological fluids without leaching ions or shedding particulates.

• Low Maintenance & Long Service Life: The absence of dynamic seals and check valves minimizes downtime, wear, and replacement costs.
