Signal iPump6S-G Industrial-Grade Peristaltic Pump with YZ35B Pump Head

Overview

The Signal iPump6S-G is an industrial-grade peristaltic pump engineered for continuous, high-reliability fluid transfer in demanding laboratory and pilot-scale process environments. It operates on the fundamental principle of positive displacement via mechanical occlusion: a rotating roller assembly compresses elastomeric tubing against a rigid housing, creating sequential “pillows” of fluid that are displaced axially with each revolution. Flow rate is determined by three interdependent variables—the rotational speed (RPM), the volumetric displacement per pillow (governed by tube inner diameter and roller geometry), and the number of pillows generated per revolution (determined by roller count and pump head configuration). This deterministic relationship ensures inherently linear, pulse-free, and contamination-free fluid handling—critical for applications where sterility, shear sensitivity, or chemical compatibility must be preserved without valve wear or seal degradation.

Key Features

• Precision Digital Control: 4-digit LED display toggles between real-time RPM and calibrated flow rate (L/min); resolution of 1 RPM enables fine-grained speed tuning for repeatable dosing.
• Multi-Mode Operation: Three independent operating modes—Speed Mode (direct RPM setpoint), Flow Mode (closed-loop estimation using pre-calibrated tube parameters), and Timer Mode (programmable run duration from 1 second to 99 hours with automatic shutdown).
• Robust Drive Architecture: Brushless DC motor delivers high torque across the full 40–600 RPM range; zero brush wear, no scheduled maintenance, and stable output under variable load conditions.
• Industrial Enclosure: 304 stainless steel chassis resists corrosion from cleaning agents, organic solvents, and ambient humidity; all internal PCBs feature triple-conformal coating (acrylic-based) for protection against moisture, condensation, and airborne contaminants.
• Directional Flexibility & Recovery Logic: Bidirectional rotation supports fill-and-empty cycles; power-fail memory retains last operational state—including mode, setpoint, and elapsed timer—ensuring process continuity after unexpected interruption.
• Scalable Integration: Optional opto-isolated analog/digital I/O modules support 0–5 V, 0–10 V, 4–20 mA, and 0–10 kHz control signals; RS485 Modbus RTU communication enables centralized supervision within SCADA or LIMS environments.

Sample Compatibility & Compliance

The iPump6S-G is compatible with a broad spectrum of chemically resistant tubing materials—including platinum-cured silicone (standard), Viton®, Tygon® B-44-3, and Pharmed® BPT—enabling safe handling of acids, bases, alcohols, and biological media. When paired with the YZ35B pump head (3-roller, single-channel), it achieves a certified flow range of 0.46–12 L/min using standard #273 or #282 silicone tubing (ID 3.2 mm and 4.8 mm respectively). The system complies with general-purpose electrical safety requirements per IEC 61010-1 (2010) for laboratory equipment. While not intrinsically rated for hazardous locations, its IP31 ingress protection provides basic resistance to vertically falling drips and solid objects >50 mm—suitable for controlled indoor settings such as QC labs, fermentation pilot plants, and spray dryer feed systems. For regulated environments, the optional Modbus-enabled configuration supports audit-ready operation when integrated with GLP/GMP-aligned data logging platforms.

Software & Data Management

The iPump6S-G operates as a standalone instrument but is designed for seamless integration into automated workflows. Its optional RS485 Modbus RTU interface allows bidirectional command execution (start/stop, direction reversal, speed/flow setpoint update) and status reporting (actual RPM, running state, fault codes). All communication adheres to standard Modbus function codes (03h, 06h, 10h), enabling interoperability with LabVIEW, MATLAB, Python-based control scripts, or commercial SCADA systems. Though no proprietary software is bundled, the pump’s register map is fully documented in the technical manual—facilitating custom script development for batch traceability, event-triggered dosing, or synchronized multi-pump coordination. When deployed with external data loggers compliant with FDA 21 CFR Part 11, timestamped operational records—including start time, duration, average flow, and error flags—can be archived for regulatory review.

Applications

• Spray Drying Feed Systems: Stable, pulse-minimized delivery of heat-sensitive slurries or protein solutions to nozzle assemblies; full-speed mode enables rapid line priming prior to atomization.
• Fermentation & Bioreactor Additions: Precise, sterile-additive metering (e.g., antifoam, base, inducers) without cross-contamination risk—tubing change eliminates cleaning validation burden.
• Centrifuge Sample Loading: Controlled introduction of viscous cell lysates or clarified supernatants into rotor buckets, minimizing splashing and ensuring balanced loading.
• Continuous Extraction & Chromatography: Mobile phase delivery in preparative LC systems where solvent compatibility and pressure independence are essential.
• Chemical Dosing in Pilot Reactors: Corrosive reagent addition (e.g., NaOH, HCl) using fluoropolymer-lined tubing; analog voltage input enables feedback-driven titration control.

FAQ

What tubing sizes are supported with the YZ35B pump head?
The YZ35B head accommodates silicone tubing with inner diameters of 3.2 mm (#273) and 4.8 mm (#282), delivering verified flow ranges of 465–7870 mL/min and 682–12000 mL/min respectively.
Is calibration required for flow mode accuracy?
Yes—flow mode relies on pre-entered tubing dimensions and material compliance characteristics; users must perform a one-time volumetric calibration at representative speeds to achieve ±2% full-scale accuracy.
Can the pump operate continuously for extended periods?
Yes—designed for 24/7 operation under nominal load; thermal management and brushless motor architecture ensure stable performance at 600 RPM for >10,000 hours MTBF.
Does the timer function retain settings during power loss?
The timer resets upon power interruption, but the pump resumes its prior operational mode and setpoint (e.g., RPM or flow value) once restored—timer duration itself is not retained.
Are replacement pump heads and tubing available through Signal authorized channels?
Yes—YZ35B heads, spare rollers, and certified silicone/Viton® tubing kits are stocked and distributed globally via Signal’s authorized partner network with documented lot traceability.
