Chuding WT600F Intelligent Dispensing Peristaltic Pump

Overview

The Chuding WT600F Intelligent Dispensing Peristaltic Pump is an industrial-grade, microprocessor-controlled fluid handling system engineered for high-precision volumetric delivery in laboratory, pilot-scale, and light industrial environments. Based on the peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the WT600F eliminates fluid contact with internal mechanical components, ensuring contamination-free operation and simplifying maintenance. Its brushless servo motor delivers consistent torque across the full speed range (0.1–600 rpm), enabling stable flow rates from 0.06 mL/min up to 6000 mL/min depending on pump head configuration and tubing selection. Designed for integration into automated workflows, the unit supports deterministic control via RS485/MODBUS RTU, isolated digital I/O, and analog speed modulation—making it suitable for use in GLP-compliant QC labs, bioprocessing skids, chemical dosing stations, and continuous-flow synthesis platforms.

Key Features

• 4.3-inch full-color TFT touchscreen with intuitive icon-driven interface and multilingual menu support (English, Chinese, Spanish)
• Four operational modes: Flow Rate Control, Volume Dispensing, Time-Based Dispensing, and Copy Dispensing—with five programmable parameter sets stored per mode
• High-resolution speed control (0.1 rpm resolution) and calibrated flow accuracy (±0.5% under standardized test conditions per ISO 8503-2)
• Integrated guided calibration wizard for rapid flow rate verification using user-provided reference volumes
• Optically isolated external control inputs (5 V / 12 V / 24 V logic, 0–5 V analog standard) with configurable start/stop, direction reversal, and timed dispensing triggers
• Conformal-coated PCBs meeting IPC-CC-830B Class 1 requirements for humidity, dust, and chemical vapor resistance
• 304 stainless steel enclosure (IP31 rated) compatible with frequent cleaning using ethanol, isopropanol, or diluted sodium hypochlorite solutions
• Thermally regulated fan system that activates only when internal temperature exceeds 35 °C—reducing acoustic emissions to <45 dB(A) at 1 m distance
• Support for interchangeable pump heads (YZ15, YZ25, KZ25) accommodating tubing IDs from 0.5 mm to 4.8 mm, enabling scalable flow profiles across applications

Sample Compatibility & Compliance

The WT600F is inherently compatible with a broad spectrum of aqueous, organic, and mildly corrosive liquids—including buffers, cell culture media, acids (up to 10% HCl, 5% HNO₃), alkalis (up to 1 M NaOH), and common solvents (e.g., acetone, methanol, DMSO)—provided appropriate tubing materials are selected (e.g., Pharmed BPT for ozone resistance, Norprene for high elasticity, Viton for hydrocarbon compatibility). The pump does not require validation against specific pharmacopeial monographs (e.g., USP <1058>) as a standalone device; however, its deterministic behavior, non-volatile memory retention, and audit-ready parameter logging (when paired with compliant SCADA software) support qualification under GMP Annex 11 and FDA 21 CFR Part 11 when deployed in regulated manufacturing processes. All electrical design complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) standards.

Software & Data Management

While the WT600F operates autonomously via its embedded firmware, it provides native interoperability with third-party control systems through its open MODBUS RTU implementation over RS485. Engineers may integrate the pump into LabVIEW, MATLAB, Python-based automation frameworks (using PyModbus), or PLC-controlled sequences without proprietary drivers. Parameter changes, runtime status (current speed, elapsed time, dispensed volume), and fault codes (e.g., tubing occlusion, motor stall, thermal overload) are accessible via MODBUS register mapping. For traceability-critical applications, external data loggers can capture timestamped events at 1 Hz resolution. The unit retains all user-defined programs and calibration offsets in non-volatile memory—even after power loss—ensuring repeatable performance across shifts and maintenance cycles.

Applications

• Automated reagent dispensing in ELISA, PCR setup, and cell seeding workflows
• Controlled feed addition in jacketed glass reactors and continuous stirred-tank reactors (CSTRs)
• Calibration standard delivery in analytical chemistry labs (e.g., ICP-MS, HPLC mobile phase preparation)
• Media perfusion in hollow-fiber bioreactors and organ-on-chip platforms
• Chemical metering in wastewater treatment pilot plants and electroplating lines
• Adhesive and coating application in R&D prototyping where shear-sensitive formulations must avoid valve-induced pulsation

FAQ

Does the WT600F support FDA 21 CFR Part 11 compliance?
The pump itself does not include electronic signature or audit trail functionality; however, its deterministic MODBUS registers and non-volatile program storage enable integration into validated systems that meet Part 11 requirements when combined with compliant host software and procedural controls.
What tubing sizes are supported with the YZ15 pump head?
YZ15 accommodates tubing inner diameters of 0.5 mm (13#), 0.76 mm (14#), 1.14 mm (16#), 1.59 mm (19#), 2.41 mm (25#), 2.79 mm (17#), and 3.18 mm (18#), delivering flow ranges from 0.06 to 2300 mL/min respectively.
Can multiple WT600F units be daisy-chained via RS485?
Yes—up to 32 devices can share a single RS485 bus using unique MODBUS slave addresses (configurable via touchscreen or external command), supporting centralized monitoring and synchronized dispensing across multi-pump configurations.
Is firmware upgrade capability available?
Field firmware updates are supported via USB-to-RS232 adapter and Chuding’s PC-based configuration utility; version history and release notes are published on the manufacturer’s technical support portal.
What safety certifications does the unit carry?
The WT600F carries CE marking (EMC Directive 2014/30/EU and LVD Directive 2014/35/EU), RoHS 2011/65/EU compliance, and conforms to GB 4793.1–2007 (Chinese equivalent of IEC 61010-1) for laboratory equipment safety.
