Overview
The Longer WT600-3J Stainless Steel Peristaltic Pump is an industrial-grade, precision fluid transfer system engineered for continuous, contamination-free operation in demanding laboratory and pilot-scale production environments. Based on the peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the WT600-3J isolates the fluid path entirely within the tubing, eliminating valves, seals, or wetted metal components. This design ensures zero risk of cross-contamination, chemical incompatibility, or sample degradation, making it ideal for handling sensitive biological buffers, aggressive solvents, abrasive slurries, and sterile media. Its robust stainless steel housing and IP55-rated enclosure provide reliable performance in high-humidity, dusty, or washdown-prone settings common in QC labs, bioprocessing suites, and analytical sample preparation workflows.
Key Features
- High-Torque Brushless DC Motor: Delivers consistent rotational force across the full 60–600 rpm range, enabling stable flow with large-diameter tubing and high-viscosity fluids—even when driving dual-channel pump heads.
- Multi-Protocol Analog & Digital Control: Supports 4–20 mA, 0.5–5 V, 1–10 V, and 1–10 kHz frequency inputs for seamless integration into PLC-controlled systems, SCADA architectures, or custom automation platforms.
- RS485 Serial Communication: Enables remote configuration, real-time status monitoring, and synchronized multi-pump operation via Modbus RTU protocol—fully compatible with LabVIEW, MATLAB, and Python-based control scripts.
- Intelligent Memory Retention: Automatically saves operational parameters—including set speed, direction, and run state—across power cycles, ensuring process continuity without manual reconfiguration.
- Full-Speed Override Button: Provides immediate maximum-speed operation for rapid line priming, system flushing, or emergency evacuation—critical during method development or maintenance procedures.
- Modular Pump Head Compatibility: Accepts YZ1515, YZII15, YZ2515, DG15-24, and KZ25 series pump heads with interchangeable tubing (ID 1.6–6.4 mm), supporting flow rates from 4.2 to 6000 mL/min per channel under calibrated conditions.
Sample Compatibility & Compliance
The WT600-3J is inherently compatible with any chemically resistant tubing material—including silicone, Viton®, Tygon® LFL, Pharmed® BPT, and C-Flex®—allowing users to select tubing based on FDA-compliant contact requirements, thermal stability, or abrasion resistance. While the base unit does not carry CE marking by default, CE-certified variants (WT600-3J-E/CE) are available upon order specification and conform to EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions). The pump’s analog and digital interfaces support audit-trail-capable control architectures aligned with GLP and GMP documentation standards. Its closed-loop speed regulation meets ASTM D4005-19 repeatability criteria for volumetric dispensing systems when paired with calibrated tubing and validated flow sensors.
Software & Data Management
No proprietary software is required for basic operation; however, Longer provides a free Windows-based configuration utility for advanced parameter tuning, firmware updates, and diagnostic logging via RS485. The pump supports timestamped event logging—including start/stop triggers, direction changes, and speed adjustments—which can be exported as CSV for traceability. When integrated into larger data acquisition ecosystems, the RS485 interface enables bidirectional communication with LIMS or ELN platforms through standard OPC UA or MQTT gateways. All analog input channels meet IEC 61000-4-5 surge immunity requirements, ensuring signal integrity in electrically noisy industrial environments.
Applications
- Continuous feeding of culture media in microbial fermentation and mammalian cell bioreactors
- Accurate dosing of reagents in automated titration and colorimetric assay systems
- Recirculation loops in HPLC solvent delivery, inline filtration, and column cleaning protocols
- Perfusion control in organ-on-chip and microfluidic tissue models
- Batch transfer of pharmaceutical intermediates in non-sterile API synthesis lines
- Environmental water sampling and on-site nutrient dosing in aquaculture monitoring stations
FAQ
Does the WT600-3J support bidirectional flow control?
Yes—the pump supports reversible rotation with programmable direction switching via front-panel buttons, analog signals, or RS485 commands.
Can it operate continuously at 600 rpm for extended periods?
Yes—its brushless DC motor and thermally optimized chassis enable uninterrupted operation at maximum speed under ambient temperatures ≤40 °C and relative humidity <90%.
Is tubing calibration required for accurate flow rate delivery?
Yes—peristaltic flow accuracy depends on tubing elasticity, wall thickness, and roller compression geometry; users must perform gravimetric or volumetric calibration per ISO 8599-1 using their selected tubing batch.
What safety certifications does the standard model hold?
The base WT600-3J complies with GB/T 14048.1 (Chinese low-voltage switchgear standard); CE-marked versions meet EMC Directive 2014/30/EU and LVD Directive 2014/35/EU upon explicit request and factory certification.
How many pump heads can be mounted simultaneously?
The WT600-3J chassis accommodates up to four single-channel pump heads (e.g., four YZ1515 units) or two dual-channel configurations (e.g., two YZII25 units), with mechanical synchronization ensured via shared drive shaft coupling.
