Overview
The HL-5/HL-6 Series Industrial Peristaltic Pumps are precision-engineered, single-channel peristaltic fluid transfer systems designed for continuous, pulse-free, and contamination-free operation in laboratory, pilot-scale, and light industrial environments. Based on the fundamental principle of peristalsis—where rollers compress flexible tubing to generate positive displacement—the HL-5/HL-6 pumps deliver highly repeatable volumetric flow without exposing internal pump components to the fluid path. This architecture eliminates the risk of cross-contamination, seals, valves, or mechanical wear associated with diaphragm or gear pumps, making them ideal for handling sensitive, abrasive, viscous, or shear-sensitive media including cell cultures, reagents, buffers, slurries, and mild corrosives. The series comprises multiple configurations—including HL-5 (standard), HL-5A (extended flow), HL-5B (digital speed display), HL-6 (high-flow base model), HL-6B (digital speed), and HL-6D (digital speed + programmable timer + fill mode)—all sharing a robust aluminum alloy chassis, thermally stable DC motor drive, and calibrated roller geometry optimized for consistent tube occlusion and long-term tubing life.
Key Features
- Single-channel design with interchangeable pump heads compatible with standard silicone or fluoropolymer tubing (ID 1.6–6.4 mm recommended)
- Digital LED speed display (HL-5B, HL-6B, HL-6D) enabling real-time RPM monitoring and precise manual adjustment via rotary encoder
- Wide speed range: 0.1–300 rpm (corresponding to 0.2–150 L/h depending on tubing ID and fluid viscosity)
- Constant-flow performance maintained across variable backpressure up to ≥196 kPa (2 kg/cm²), validated under ISO 8573-1 clean air conditions
- Non-volatile memory retains last-used speed and timer settings after power cycle (HL-5B/HL-6B/HL-6D)
- HL-6D variant supports programmable run time (1 sec–99 hr 59 min), automatic stop, and volumetric fill mode with flow-based volume calculation
- Front-panel controls with tactile feedback; optional RS-485 interface available for integration into SCADA or PLC-controlled systems (custom order)
- IP20-rated enclosure suitable for controlled indoor environments; CE-compliant per EN 61000-6-2/6-4 and EN 61010-1 for laboratory use
Sample Compatibility & Compliance
These pumps accommodate a broad spectrum of liquid samples without chemical degradation or particulate generation, provided tubing material is selected appropriately (e.g., platinum-cured silicone for biocompatibility, Pharmed® BPT for solvent resistance). They support GLP-aligned workflows through traceable speed calibration and operator-auditable parameter logging (when paired with external data acquisition). While not certified for Class I Div 1 hazardous locations, they meet general-purpose safety requirements for non-explosive laboratory and process areas. No regulatory certification (e.g., FDA 21 CFR Part 11, ISO 13485) is claimed for the base unit; however, system-level validation documentation can be supported upon request for IQ/OQ protocols in GMP-relevant applications.
Software & Data Management
The HL-5/HL-6 series operates as a standalone instrument with no bundled PC software. All configuration and operation occur via front-panel interface. For automated data capture, third-party DAQ systems may acquire analog 0–10 V or 4–20 mA speed output signals (available on HL-6D with optional module). HL-6D’s internal timer and fill functions generate discrete event logs (start/stop timestamps, total volume dispensed) stored in volatile memory—sufficient for batch record linkage when exported manually. Audit trails require external timestamped logging; no built-in electronic signature or user access control is implemented.
Applications
- Continuous feed in bioreactor nutrient or pH-control loops
- Reagent delivery in automated titration or colorimetric analyzers
- Media preparation and sterile filtration line priming
- Chromatography mobile phase delivery (low-pressure HPLC prep systems)
- Wastewater sampling and effluent dosing in environmental monitoring stations
- Pharmaceutical excipient transfer during oral suspension formulation
- Calibration standard distribution in metrology labs requiring low-shear, metered flow
FAQ
What tubing sizes are compatible with the HL-5/HL-6 pump heads?
Standard pump heads accept tubing with inner diameters from 1.6 mm to 6.4 mm; optimal flow linearity and pressure tolerance are achieved using 3.2 mm or 4.8 mm ID silicone tubing.
Is the flow rate linearly proportional to rotational speed?
Yes—within ±3% deviation across the full speed range when using uniform-walled, elastomeric tubing and constant backpressure below rated maximum.
Can the HL-6D perform volumetric dispensing without external sensors?
Yes—the HL-6D calculates dispensed volume based on calibrated flow rate (L/h) × elapsed time, supporting preset fill volumes up to 999.9 L with ±5% accuracy under stable operating conditions.
Does the pump support remote start/stop via digital input?
Not by default; however, an optional dry-contact trigger interface kit (model HL-IO-KIT) enables external TTL or relay-based control of run/stop functions.
What maintenance is required to ensure long-term accuracy?
Routine inspection of tubing compression and replacement every 100–500 hours of operation (depending on speed, pressure, and tubing type); periodic verification of roller alignment and motor encoder response using manufacturer-provided calibration procedure.
