Single Head Electrolyte Injection Pump Precision Quantitative Metering Dispenser

Product Overview

This high-precision single head electrolyte injection pump is an advanced positive-displacement fluid metering solution engineered specifically for rigorous micro-volume liquid dispensing. Utilizing a specialized valveless ceramic rotary plunger design, this equipment eliminates the mechanical vulnerabilities of conventional metering pumps to deliver continuous, pulseless, and ultra-accurate chemical volumetric delivery.

Primarily developed for lithium-ion battery electrolyte filling, electrochemical research, and high-precision fluid dosing across pharmaceutical, biochemical, adhesive, and fine chemical processing, this system provides unmatched chemical inertia. It operates seamlessly with corrosive organic carbonates, lithium salts, aggressive solvents, and high-viscosity reagents without risking cross-contamination or mechanical breakdown.

Constructed with industrial-grade stainless steel housings and ultra-hard alumina ceramic core components, the dispensing unit delivers dependable consistency across millions of operational cycles. With zero dynamic seals, full clean-in-place capabilities, and a digital programmable motion interface, this equipment provides research facilities and automated manufacturing lines with exceptional reliability and zero routine maintenance overhead.

Key Features

• Valveless Positive-Displacement Ceramic Rotary Mechanism: The core fluid path utilizes a precision-machined alumina ceramic rotary plunger that simultaneously alternates port alignment and stroke displacement, completely eliminating the need for conventional check valves and preventing common clogging, backflow, and priming failures.
• Extreme Wear and Chemical Corrosion Resistance: Manufactured with high-purity $Al_2O_3$ alumina ceramics boasting a surface hardness of 1800 HV0.5, the wetted structural components resist concentrated acids, alkalis, abrasive crystalline slurries, and organic battery electrolyte solvents without degradation or chemical leaching.
• Seal-Free Architecture with Zero Routine Maintenance: By pairing microscopic dimensional tolerances with naturally low friction coefficients, this equipment operates entirely without elastomeric dynamic seals, O-rings, or consumable packing, resulting in virtually zero friction wear, leak-free operation, and zero scheduled maintenance downtime.
• High-Precision Digital Stepper Actuation: Driven by an industrial single-axis 86 series high-torque stepper motor, the system provides precise rotational and linear indexing across an operating speed spectrum of 18 to 250 rpm, maintaining an exceptional volumetric stroke repeatability accuracy within ±3‰ (±0.3%).
• Microliter-Scale Wide Dispensing Dynamic Range: A calibrated mechanical gear adjustment mechanism permits fluid delivery modulation from 0.05 µL up to 3000 µL per individual stroke, supporting maximum throughput rates up to 750 mL/min for versatile scalability between micro-dosing and bulk filling.
• Clean-In-Place Bidirectional Flushing: Routine line flushing, cleaning, and chemical sterilization can be executed fully online without disassembling the pump assembly, achieved simply by toggling bidirectional motor rotation to reverse fluid pathways directly through the user interface.
• Programmable Controller with Touchscreen Interface: The intelligent digital HMI and integrated PLC allow operators to program custom dispensing profiles, adjust rotation speeds, set cycle counters, manage batch allocations, and fine-tune acceleration curves without manual mechanical intervention.
• Modular Demountable SUS304 Enclosure: All non-ceramic structural elements, pump sleeves, and mechanical mountings are fabricated from robust SUS304 stainless steel, offering an IP-rated barrier against corrosive laboratory vapors and allowing rapid complete teardown when physical inspection is required.
• Versatile Chemical Tubing Interface: Outfitted with dedicated 6.0 x 8.0 mm inlet and 4.0 x 6.0 mm discharge interfaces compatible with chemically inert PE and PTFE fluid lines, ensuring universal compatibility across diverse chemical synthesis and battery assembly setups.
• OEM and Automation Ready: Designed with standardized electrical communication protocols and an ultra-compact benchtop footprint, this unit integrates seamlessly into automated battery assembly lines, glovebox chambers, robotic workstations, and customized industrial machinery.
