FS-R-01 Peristaltic Pump

Overview

The FS-R-01 Peristaltic Pump is an industrial-grade, microprocessor-controlled fluid transfer system engineered for precision dosing, continuous circulation, and repeatable peristaltic delivery in laboratory, pilot-scale, and light industrial applications. Based on the fundamental principle of occlusion-based positive displacement—where rollers compress a flexible tubing segment against a rigid housing to generate unidirectional flow—the FS-R-01 delivers pulse-free, contamination-free fluid handling without valves, seals, or internal wetted surfaces. Its brushless DC motor drive ensures low maintenance, extended service life, and consistent torque across the full speed range. Designed for integration into automated analytical workflows, bioprocessing skids, environmental monitoring stations, and chemical feed systems, the pump meets core engineering requirements for traceability, repeatability, and interoperability with programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) platforms.

Key Features

• Wide operational speed range: 0.1–600 rpm, enabling precise control from ultra-slow reagent addition to high-throughput media transfer
• High-flow capacity up to 12,000 mL/min (dependent on tubing ID and fluid viscosity), supporting both capillary and bulk liquid handling
• Flow accuracy of ±0.5% under calibrated conditions, verified using gravimetric or volumetric reference methods per ISO 8599 and ASTM D3417
• Dual-resolution speed control: 0.1 rpm resolution below 100 rpm for fine-tuning; 1 rpm resolution above 100 rpm for robust operational stability
• Standard analog input compatibility (0–5 V DC) and optional support for 0–10 V, 4–20 mA, and 0–10 kΩ potentiometer inputs—facilitating seamless integration with process controllers and PID loops
• Programmable TTL-level external control: start/stop and direction reversal via 5 V TTL (standard), with optional 12 V or 24 V TTL support for legacy or custom logic systems
• Bidirectional RS232 and RS485 serial interfaces compliant with EIA/TIA-232-F and EIA/TIA-485-A standards, enabling remote configuration, real-time parameter monitoring, and audit-trail-capable command logging
• Dedicated DC 12 V power output for auxiliary sensors or solenoid valves; DC 5 V logic-level output for synchronization with external timing circuits
• Multi-voltage power supply options: AC 220 V ±10% (standard), with field-selectable AC 110 V or AC 380 V variants for global deployment in compliance with IEC 61000-3-2 harmonic emission limits

Sample Compatibility & Compliance

The FS-R-01 is compatible with a broad spectrum of elastomeric tubing materials—including silicone, Viton®, Tygon® LFL, and Pharmapure®—allowing adaptation to diverse chemical, thermal, and regulatory requirements. Tubing selection directly governs maximum pressure rating (up to 2.5 bar at low speeds), temperature tolerance (–20 °C to +80 °C depending on material), and USP Class VI or FDA 21 CFR Part 177 compliance where required. The pump’s IP31 enclosure provides protection against vertically falling drips and solid objects >2.5 mm, making it suitable for controlled laboratory environments and non-hazardous industrial zones. While not intrinsically safe, its design supports installation in Class I, Division 2 areas when paired with appropriate barrier instrumentation. All firmware operations adhere to deterministic timing constraints, supporting validation under GLP and GMP frameworks where electronic records must satisfy FDA 21 CFR Part 11 requirements for audit trails and user authentication.

Software & Data Management

No proprietary software is bundled; however, the RS232/RS485 interface implements a documented ASCII command protocol supporting ASCII-based queries and parameter writes (e.g., “SPEED=325”, “DIR=REV”, “START”). Third-party integration is enabled via Modbus RTU (over RS485) through optional firmware upgrade, allowing direct mapping into SCADA HMI tags and PLC memory registers. Command logs—including timestamped execution of speed changes, direction reversals, and fault events—are accessible via serial polling and can be parsed into CSV or JSON for archival in LIMS or MES platforms. Firmware updates are performed via UART bootloader mode, preserving configuration parameters across revisions. Configuration persistence is ensured by non-volatile EEPROM storage with write-cycle endurance exceeding 100,000 cycles.

Applications

• Automated sample introduction in ICP-OES, HPLC, and ion chromatography systems
• Controlled nutrient or acid/base dosing in bioreactor pH and DO control loops
• Continuous wastewater sampling for online analyzers (e.g., COD, NH₃-N, turbidity)
• Reagent delivery in clinical chemistry analyzers and ELISA wash stations
• Media circulation in cell culture incubators and perfusion bioreactors
• Calibration standard delivery in metrology labs performing flowmeter verification per ISO/IEC 17025
• Chemical metering in small-scale water treatment pilot plants

FAQ

What tubing sizes are supported?
The FS-R-01 accommodates tubing inner diameters from 0.5 mm to 16 mm, depending on roller configuration and pump head model. Standard head supports 3.2–12.7 mm ID; optional high-torque heads extend compatibility to 16 mm ID for high-viscosity fluids.

Can the pump operate in reverse continuously?
Yes—bidirectional operation is fully rated and supported for indefinite duty cycle in either direction, with identical torque and flow characteristics.

Is flow calibration traceable to national standards?
While the pump itself is not NIST-traceable as a standalone instrument, its ±0.5% flow accuracy specification is validated using NIST-traceable gravimetric measurement systems per ISO 5167-3 and ASTM D1193 protocols during factory acceptance testing.

Does the RS485 interface support Modbus RTU out of the box?
Modbus RTU is available via firmware update; default operation uses the native ASCII command set. Contact technical support for version-specific Modbus register maps and configuration guides.

What is the expected service life of the drive mechanism?
Under continuous operation at ≤75% of maximum speed and ambient temperature <35 °C, the brushless DC motor and gear train are rated for ≥20,000 hours MTBF, per MIL-HDBK-217F predictions.
