Overview
The Behr PLP Series Laboratory Peristaltic Pump is an engineered solution for precise, contamination-free fluid handling in analytical, pharmaceutical, biotechnology, and environmental laboratories. Based on the peristaltic principle—where rollers compress flexible tubing to create a positive displacement flow—the PLP Series ensures complete fluid isolation from pump mechanics, eliminating risk of cross-contamination, leakage, or seal degradation. Designed and assembled in Germany under strict quality control protocols, each unit integrates a robust AC induction motor with thermally protected windings, optimized for continuous-duty operation at ambient laboratory conditions. The dual-roller compression head, combined with four precision-machined guide rollers, delivers consistent occlusion and high volumetric accuracy across the full flow range. This architecture minimizes pulsation while maintaining mechanical stability during extended runs—critical for applications requiring reproducible dosing, media transfer, or inline sampling.
Key Features
- Tool-free tubing installation and replacement—no wrenches, clamps, or alignment fixtures required; standard silicone or PharMed® BPT tubing fits securely in under 15 seconds
- Dual-roller compression system with adjustable occlusion depth, enabling fine-tuned flow calibration and extended tubing life
- AC motor options: 220 V / 50 Hz (standard EU configuration) and 115 V / 60 Hz (North American variant), both equipped with thermal overload protection and IP20-rated enclosures
- Four guide rollers ensure uniform tubing support, reducing lateral stress and preventing kinking or premature fatigue during high-cycle operation
- Compact footprint (PLP 330: 185 × 120 × 170 mm) suitable for benchtop integration, fume hoods, or automated workstations
- Motor speed continuously adjustable via front-panel potentiometer (0–100% range), with analog tachometer output available for external monitoring
Sample Compatibility & Compliance
The PLP Series accommodates a broad spectrum of chemically compatible tubing materials—including silicone, Viton®, Tygon® E-3603, and USP Class VI-certified PharMed® BPT—enabling safe handling of aqueous buffers, organic solvents, acids, bases, cell culture media, and viscous suspensions up to 10,000 cP. All models comply with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity requirements). Electrical safety conforms to EN 61010-1:2019 for laboratory equipment, including protection against electric shock, mechanical hazards, and abnormal heat generation. While not intrinsically rated for hazardous locations, optional explosion-proof motor variants (ATEX Zone 2 / Class I Div 2) are available upon request for regulated process environments.
Software & Data Management
The base PLP Series operates as a standalone analog-controlled instrument, prioritizing reliability and operational simplicity. For laboratories requiring digital integration, optional RS-485 Modbus RTU or 0–10 V analog interface modules enable connection to SCADA systems, LIMS platforms, or custom LabVIEW/Python-based automation frameworks. Firmware-upgradable controllers support time-stamped flow logging (with external data logger), audit trail generation, and user-access level management—facilitating compliance with GLP, GMP, and FDA 21 CFR Part 11 requirements when deployed with validated electronic record systems. Calibration certificates traceable to DAkkS-accredited national standards are provided with each unit upon request.
Applications
- Continuous feeding of reagents into ICP-MS, HPLC, or ion chromatography systems
- Accurate delivery of cell culture media, harvest streams, or buffer solutions in bioprocessing workflows
- In-line sampling for real-time pH, conductivity, or turbidity monitoring in fermentation or wastewater treatment studies
- Controlled dosing of coagulants or flocculants in environmental water quality testing (ASTM D1976, ISO 7027)
- Automated titration and dilution protocols in QC/QA labs compliant with ISO/IEC 17025
- Low-shear transfer of shear-sensitive biologics, liposomes, or microencapsulated formulations
FAQ
What tubing sizes are supported by the PLP Series?
Standard configurations accommodate inner diameters from 0.5 mm to 16 mm, depending on model and flow range. Recommended wall thickness: 1.0–2.5 mm for optimal occlusion and longevity.
Can the pump be integrated into a PLC-controlled system?
Yes—via optional RS-485 Modbus RTU or 0–10 V analog input/output modules, supporting start/stop, speed control, and status feedback in industrial automation architectures.
Is validation documentation available for GMP environments?
Factory-issued IQ/OQ protocols, traceable calibration reports, and material compliance statements (e.g., USP Class VI, FDA 21 CFR 177.2600) are supplied upon order confirmation.
How often does the tubing require replacement under continuous operation?
Typical service life ranges from 100–500 hours depending on flow rate, tubing material, and fluid abrasiveness; a wear-monitoring schedule is included in the operator manual.
Does Behr offer technical support for international customers?
Yes—authorized distributors provide local language documentation, application engineering consultation, and warranty service aligned with ISO 9001-certified support processes.
