Plunger Pump Feeding Device for Adjustable Laboratory Slurry Delivery and Coating Equipment

Product Overview

This plunger pump feeding device provides controlled slurry delivery for laboratory coating and material processing workflows. A stepper motor drives the syringe piston through a screw mechanism, allowing the delivery rate to be adjusted to match the feed requirement of the coating equipment. The system is designed for stable, repeatable material transfer in applications where controlled flow is essential.

The equipment is suitable for battery electrode research, laboratory coating processes, and advanced materials development. It can operate in coordination with a coating machine, making it useful for slurry preparation and film-forming workflows that require synchronized feeding. Its interchangeable syringe configuration also supports practical switching between different working volumes.

The unit is designed for convenient operation and maintenance in demanding research environments. Instantaneous stopping helps prevent slurry dripping after delivery pauses, while the compact enclosure and straightforward construction support efficient installation, cleaning, and routine service.

Key Features

• Adjustable Piston Speed: The stepper motor controls screw rotation and provides a piston speed range of 0.05-5 mm/s. This allows the delivery rate to be matched to the requirements of the connected coating equipment.

• Instantaneous Stop Function: The drive can stop the syringe piston immediately when feeding is paused. This helps limit slurry dripping, supports cleaner operation, and reduces the maintenance burden associated with unwanted material leakage.

• Interchangeable Syringe Configuration: The system supports selectable syringe sizes, with 20 ml, 30 ml, and 50 ml PP syringes supplied as standard. Operators can select a suitable volume for the test batch or coating workflow.

• Stepper Motor Drive: Stepper motor actuation provides controlled piston movement through a screw-driven mechanism. This arrangement supports consistent feed adjustment during laboratory-scale material processing.

• Coating Machine Integration: The equipment can be operated in conjunction with a coating machine. This enables a more coordinated slurry feeding process for electrode coating and other continuous or semi-continuous laboratory film applications.

• Low-Dead-Volume Tubing Path: The standard PTFE tube has a 3.2 mm outside diameter and 1.6 mm inside diameter. The defined tubing dimensions provide a controlled connection between the syringe and the downstream coating process.

• Compact Laboratory Footprint: Measuring 400 x 200 x 230 mm, the unit occupies limited bench space while retaining the core functions required for controlled slurry delivery. Its compact format is suitable for research laboratories and pilot-scale development areas.

• Simplified Maintenance: The equipment uses a practical syringe-and-tubing delivery arrangement and has a clean external design. These characteristics help operators access consumable flow-path components and carry out routine maintenance efficiently.

Applications

Technical Specifications

The piston speed is the primary operating parameter for matching slurry delivery to a downstream coating process. The available range of 0.05-5 mm/s gives operators a broad adjustment window for laboratory-scale feeding conditions. Because the reference specification defines this value as syringe piston speed, it should be evaluated together with the selected syringe capacity, slurry properties, and coating-machine requirements when establishing a process recipe.

The standard syringe set includes 20 ml, 30 ml, and 50 ml PP options. This provides a practical choice between smaller experimental batches and longer feeding intervals within the same laboratory workflow. Selecting the appropriate syringe volume can help reduce unnecessary material hold-up and support more efficient use of research slurry. The syringe configuration is also selectable, allowing the setup to be changed when the experimental batch size or process requirement changes.

The material path uses PTFE tubing with a 3.2 mm outside diameter and 1.6 mm inside diameter. These dimensions define the standard connection between the syringe assembly and the coating equipment. Operators should maintain the tubing path appropriately for their slurry formulation and application conditions, particularly when changing materials between experiments.

A maximum 100 mm piston stroke defines the available travel of the syringe drive. The stepper motor provides the mechanical drive for this movement and enables the screw speed to be controlled through the operating system. The instant-stop capability is important in coating workflows because it helps halt material movement promptly when the feed cycle is interrupted. This helps reduce dripping at the outlet and supports a cleaner working area.

The unit can be linked with a coating machine, allowing the feeding device to form part of an integrated laboratory coating arrangement. This connection is useful for researchers who need the material supply and coating operation to function as coordinated process steps. The actual operating setup should be selected according to the requirements of the connected coating equipment and the slurry being processed.

With dimensions of 400 x 200 x 230 mm and a weight of 8 kg, the equipment is sized for laboratory installation and repositioning. The single-phase 100-240 VAC power supply with 50/60 Hz frequency supports use across common laboratory electrical environments within the stated range. Its 120 W power rating reflects the specified electrical requirement for the drive and operating system.
