Single Head Electrolyte Filling Pump Precision Ceramic Metering System

Product Overview

This single-head electrolyte filling pump is a precision positive-displacement metering system designed for controlled delivery of small liquid volumes. Its special ceramic rotary plunger valve provides stable, repeatable dosing while supporting fluids that may be chemically aggressive, abrasive, acidic, alkaline, or temperature-sensitive. A stainless-steel pump sleeve and pump body reinforce the fluid path for demanding laboratory and production environments.

The equipment is suitable for lithium-ion battery manufacturing, pharmaceutical filling, food processing, chemical handling, and adhesive dispensing. It combines programmable control, touchscreen operation, stepper-motor drive, and digital motion adjustment in a compact unit. Its wide single-stroke range and adjustable operating speed allow users to configure output for different filling processes.

The design prioritizes long service life and consistent operation. There are no dynamic seals or conventional wearing parts in the pump structure, helping minimize maintenance requirements. Online cleaning and disinfection can be completed without disassembly by switching the valve between forward and reverse directions. The pump body can also be completely dismantled when thorough inspection or service is required.

Key Features

• Precision Ceramic Rotary Plunger Valve: The special positive-displacement rotary plunger valve uses aluminum oxide ceramic to deliver controlled and repeatable liquid metering. Its high hardness and low friction characteristics support stable operation over extended cycles.

• Broad Chemical Compatibility: The fluid-contact design resists chemical reaction and is compatible with most fluids used in the stated battery, pharmaceutical, food, chemical, and adhesive applications. The construction is also resistant to high temperature, wear, acids, and alkalis.

• Stable Micro-Volume Dispensing: A single-stroke range of 0.05-3000ul supports both very small dosing requirements and higher-volume filling tasks. Stroke adjustment through a gear mechanism helps operators configure the required delivery volume.

• High Repeatability: Stroke accuracy of ±3‰ supports consistent filling results across repeated production cycles. Positive-displacement operation helps maintain reliable output when the process requires controlled, measurable dosing.

• Durable Stainless-Steel Construction: The pump sleeve and pump body are manufactured from SUS304 stainless steel. This provides a robust fluid-path structure for regular use in demanding laboratory and industrial environments.

• Low-Maintenance Architecture: The pump has no dynamic sealing components and no easily worn parts identified in the reference design. This eliminates routine maintenance and servicing costs associated with those components.

• Online Cleaning Capability: Daily cleaning and disinfection do not require pump disassembly. Operators can switch the valve forward and backward to clear the fluid path through the valve, supporting faster process turnaround.

• Programmable Touchscreen Control: A programmable controller and touchscreen human-machine interface provide convenient operation and process control. Users can digitally adjust motor motion parameters for different dispensing requirements.

• Reliable Stepper-Motor Drive: A single-axis 86-series stepper motor drives the system. The motor architecture supports controlled movement, adjustable operating parameters, and stable long-duration operation.

• OEM-Ready Configuration: The unit can be used for OEM integration, allowing equipment builders to incorporate precision electrolyte or liquid dispensing into their own automated systems and specialized filling lines.

Applications

Technical Specifications

The compact 234x125x146mm footprint makes the unit practical for laboratory benches, pilot production stations, and integrated filling equipment. Its 18-250r/min throughput speed range allows the operator or system designer to select a suitable operating condition for the required process. The maximum flow rate of 750ml/min provides additional capacity when the filling task moves beyond micro-volume dispensing.

The 0.05-3000ul single-stroke range is a key selection factor for battery, pharmaceutical, chemical, and adhesive applications. It enables the same equipment platform to address low-volume precision work as well as larger individual filling requirements. The gear-based stroke adjustment provides a direct mechanical method for setting the stroke volume, while the touchscreen and programmable controller support convenient operation and digital adjustment of motor motion parameters.

The fluid path combines an Al2O3 ceramic valve with a SUS304 pump sleeve and pump body. The ceramic valve hardness of 1800/HV0.5 is intended to support resistance to wear during repeated operation. The material combination also addresses environments where the liquid may expose the mechanism to heat, acids, alkalis, abrasive characteristics, or chemical interaction. Tubing is specified as PE/PTEE, with a 6.0x8.0mm inlet and a 4.0x6.0nn outlet.

Cleaning efficiency is another important consideration for production users. The valve can be switched in both directions to support online clearing, cleaning, and disinfection without removing the pump from the equipment. This reduces interruption during routine daily sanitation. When deeper inspection is required, the pump body can be fully dismantled, giving maintenance personnel access to the internal structure.

The absence of dynamic sealing components and identified easily worn parts reduces the number of routine service items. This design is intended to lower maintenance and upkeep costs while supporting high-performance, long-life, high-strength repeated operation. Users should still select operating conditions and cleaning procedures according to the compatibility of their specific fluids and process requirements.

From a control perspective, the single-axis 86-series stepper motor provides the drive force for the rotary plunger mechanism. Digital adjustment of motor motion parameters allows the filling behavior to be configured for different liquids and production speeds. The touchscreen human-machine interface makes routine operation more accessible for laboratory technicians, equipment operators, and OEM system integrators.

For OEM projects, the compact structure, programmable control, adjustable stroke, and defined tubing interfaces provide a practical starting point for custom liquid-filling equipment. The unit can be evaluated as a standalone metering device or incorporated into a larger battery, pharmaceutical, food, chemical, or adhesive dispensing system. Its combination of ceramic wear resistance, stainless-steel construction, low-maintenance architecture, and online cleaning capability is suited to applications that require dependable operation over repeated cycles.
