HL-6 Industrial-Grade Single-Channel High-Flow Peristaltic Pump

Overview

The HL-6 Industrial-Grade Single-Channel High-Flow Peristaltic Pump is a robust, microprocessor-controlled peristaltic pumping system engineered for continuous, pulse-free fluid transfer in demanding industrial and pilot-scale laboratory environments. Based on the principle of positive displacement via roller compression of elastomeric tubing, the HL-6 delivers precise volumetric flow without internal valves, seals, or fluid-contacting mechanical components—eliminating cross-contamination risk and minimizing maintenance. Its design prioritizes operational stability under variable back pressure conditions, with verified performance at sustained pressures ≥2 kg/cm² (≈0.2 MPa), making it suitable for applications involving viscous liquids, slurries, or systems with elevated line resistance. Unlike benchtop analytical peristaltic pumps, the HL-6 features an industrial-grade motor drive, reinforced housing, and thermal management architecture optimized for 24/7 operation in ambient temperatures ranging from 5 °C to 40 °C.

Key Features

• Single-channel configuration with modular tubing path—compatible with standard peristaltic pump tubing sizes (ID 3.2 mm to 16 mm, depending on flow target and pressure requirement)
• Wide adjustable speed range enabling fine-tuned flow control across the full 2000–150,000 mL/h span, calibrated to ±2% full-scale accuracy under steady-state conditions
• Real-time rotational speed display (RPM) via integrated LED interface; no external controller required for basic operation
• Non-volatile memory retains last-used speed setting and operational mode after power cycle—reducing setup time during repeated batch operations
• Front-panel tactile controls with status indicators for power, direction, and fault conditions (e.g., tubing occlusion, motor overload)
• IP54-rated enclosure for dust and splash resistance—suitable for non-hazardous industrial settings per IEC 60529
• Mounting provisions (M4 threaded holes) for panel, rack, or frame integration in OEM or skid-mounted process systems

Sample Compatibility & Compliance

The HL-6 handles a broad spectrum of chemically aggressive, shear-sensitive, or particulate-laden fluids—including acids, bases, solvents, fermentation broths, cell culture media, and abrasive suspensions—provided compatible tubing materials (e.g., PharMed® BPT, Norprene®, or silicone) are selected per chemical resistance charts (per ASTM D471). It meets electromagnetic compatibility requirements per IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission), ensuring reliable operation in electrically noisy plant environments. While not certified for pharmaceutical GMP manufacturing out-of-the-box, its design supports validation documentation (IQ/OQ protocols) and aligns with core elements of FDA 21 CFR Part 11 when paired with compliant data logging software and audit-trail-enabled controllers.

Software & Data Management

The base HL-6 operates as a standalone unit with local speed control and memory retention. For advanced integration, optional analog (0–10 V / 4–20 mA) and digital (RS-485 Modbus RTU) interfaces enable remote speed modulation, start/stop commands, and real-time RPM feedback into SCADA, DCS, or LIMS platforms. When connected to validated third-party software (e.g., LabVIEW™ with NI-DAQ or custom Python-based control suites), the pump supports time-stamped flow logging, batch record generation, and alarm-triggered event capture—facilitating traceability in GLP-compliant testing or quality assurance workflows. Firmware updates are performed via USB port using manufacturer-provided utilities, with version history retained in device EEPROM.

Applications

• Continuous feed in wastewater treatment pilot plants (e.g., coagulant dosing, sludge recirculation)
• Media delivery in bioreactor trains and single-use bioprocessing systems
• High-volume solvent transfer in chemical synthesis scale-up and extraction processes
• Automated filling of intermediate bulk containers (IBCs) and drums in food, beverage, and cosmetic production lines
• Calibration fluid circulation in HVAC hydronic loop testing and heat exchanger performance evaluation
• Robust sample introduction in online monitoring systems (e.g., coupled with UV-Vis spectrophotometers or conductivity analyzers)

FAQ

What tubing sizes are recommended for maximum flow rate (150,000 mL/h)?

For optimal performance at upper flow rates, use tubing with an inner diameter of 12–16 mm (e.g., Norprene® LFT-16) and confirm wall thickness compatibility with the HL-6’s roller assembly per the manufacturer’s tubing guide.
Can the HL-6 be operated in reverse rotation?

Yes—the front-panel direction switch allows reversible operation for priming, backflushing, or bidirectional process control without hardware modification.
Is the pump suitable for sterile applications?

Sterility is achieved through tubing selection and autoclaving (if tubing material permits); the pump head itself is not autoclavable but can be cleaned with IPA or 70% ethanol between batches.
Does the HL-6 support analog speed control from a PLC?

Yes—via optional 0–10 V or 4–20 mA input, enabling closed-loop flow regulation using external PID controllers or programmable logic controllers.
What is the expected service life of the rollers and tubing under continuous operation?

With proper tubing selection and maintenance, roller assemblies typically exceed 10,000 hours of service life; tubing lifetime varies by chemical exposure and flow rate—consult tubing vendor lifespan charts under defined operating conditions.
