Integrated Ceramic Valveless Metering Pump — Product Specification & Description

1. Product Overview

The Integrated Ceramic Valveless Metering Pump combines a precision ceramic pump head, a high-torque drive motor, and an intelligent motion controller into a single compact housing. Utilizing a valveless, rotating-and-reciprocating ceramic plunger mechanism, this pump performs intake and discharge functions simultaneously through plunger motion. By eliminating internal check valves, dynamic seals, and complex external wiring, it delivers space-saving, maintenance-free, and high-precision liquid dispensing for automated industrial and laboratory equipment.

2. Key Features & Advantages

• Compact All-In-One Design: Fully integrates the driver, controller, and valveless ceramic pump head into a single plug-and-play module, minimizing system footprint and cabinet wiring complexity.

• Valveless Positive Displacement: Replaces conventional check valves and springs with a single rotating-reciprocating ceramic plunger, eliminating valve clogging, jamming, and mechanical backflow.

• High Volumetric Accuracy: Delivers precise volumetric dosing with accuracy within $le pm0.4%$ and repeatability of $le 0.2%$ across low-to-medium viscosity fluids.

• Sapphire-Grade Ceramic Fluid Path: High-purity Zirconia ($ZrO_2$) or Alumina ($Al_2O_3$) plungers and sleeves feature tight clearance fits ($le 2,mutext{m}$), offering self-lubricating, wear-resistant, and particle-free performance.

• Universal Chemical Resistance: Inert ceramic wetted surfaces withstand aggressive acids, strong bases, organic solvents, and sterile bio-fluids without corrosion or metal ion contamination.
