Product Overview
This high-precision plunger pump liquid injection system is engineered for micro-volume liquid metering, high-accuracy dispensing, and chemical fluid transfer in advanced manufacturing environments. Designed specifically to meet the stringent demands of lithium-ion cylindrical cell fabrication, battery research and development, and specialized chemical dosing, this equipment delivers ultra-stable flow dynamics without fluid pulsation. Utilizing a rotary positive-displacement plunger mechanism combined with high-purity ceramic core assemblies, the system eliminates mechanical valve delays, providing an exceptionally stable volumetric delivery across continuous and batch dispensing cycles.
Built to handle corrosive, high-viscosity, and abrasive fluids, this dispensing unit serves critical roles across the clean energy, biomedical, pharmaceutical, chemical synthesis, and electronics manufacturing sectors. From precision electrolyte injection in battery research laboratories to automated reagent dispensing in production lines, the system ensures zero liquid dripping, bubble-free fluid paths, and consistent volumetric output. The integrated programmable control interface allows seamless switching between diverse operating modes, accommodating varied fluid viscosities and production throughput requirements with minimal setup time.
Engineered for high operational stability under rigorous industrial conditions, this equipment features high-density ceramic mating components fabricated through advanced gel-casting and nanostructuring techniques. The completely valveless, seal-free architecture removes conventional dynamic elastomeric seals, effectively eliminating fluid contamination, component wear, and unexpected system downtime. Whether integrated into automated manufacturing lines via standard industrial communication protocols or deployed as a standalone precision dosing bench, this system delivers uncompromising reliability, precision, and longevity for demanding research and manufacturing operations.
Key Features
- Valveless Positive Displacement Technology: The synchronized reciprocating and rotary motion of the ceramic plunger alternately opens and closes the inlet and outlet ports without mechanical check valves, achieving ultra-stable volumetric transfer with metering precision within ±0.3% to ±0.5%.
- Advanced Ceramic Pump Core Construction: Manufactured from high-purity Zirconia (ZrO₂) and Alumina (Al₂O₃), the pump core exhibits exceptional wear resistance, broad acid and alkali chemical compatibility, high hardness, and superior thermal tolerance for fluids up to 250°C.
- Self-Sealing and Self-Lubricating Architecture: Engineered using advanced gel casting and precision nanoscale pairing with 2 µm clearance tolerances, the ceramic mating components provide natural fluid sealing and lubrication without requiring auxiliary dynamic O-rings or external lubricants.
- Zero-Contamination Fluid Path: All wetted components are constructed from chemically inert industrial ceramics and fluoropolymer fluid lines, preventing metallic ion shedding, side reactions, clogging, fluid crystallization, and cross-contamination during sensitive battery electrolyte and pharmaceutical dosing.
- Smart Programmable Motion Control: Driven by an imported precision stepper or servo motor with a 1–1200 rpm speed range, the unit offers bidirectional rotation, programmable suction, discharge, reverse draw-back (anti-drip), delay dispensing, and automated standby cleaning cycles.
- Intuitive Touchscreen Interface: The 4.3-inch human-machine interface (HMI) paired with an industrial programmable logic controller enables straightforward recipe configuration, recipe storage for up to 100 distinct programs, batch fluid calculation, and multi-level password protection against unauthorized tampering.
- Flexible Automation Integration: Equipped with standard industrial communication ports, the system functions seamlessly as an independent benchtop liquid injection device or connects effortlessly to centralized PLCs, industrial computers, and automated cell assembly lines.
- Minimal Maintenance Design: With only a single moving mechanical part and no perishable dynamic seals or mechanical springs, the equipment minimizes spare parts consumption, simplifies routine sanitization, and significantly reduces long-term operational costs.
