Overview
The LongerPump dPOFLEX GP01 Industrial Peristaltic Pump is an engineered solution for continuous, precise, and reliable fluid transfer in demanding industrial and regulated laboratory environments. Based on the peristaltic principle—where rollers compress a flexible tube to generate positive displacement—the dPOFLEX GP01 eliminates fluid contact with mechanical components, ensuring contamination-free operation and simplifying maintenance. Designed for integration into process lines, bioreactor feed systems, chemical dosing loops, and automated analytical workflows, it delivers high flow capacity (up to 17 L/min) while maintaining sub-milliliter accuracy across dynamic operating conditions. Its die-cast aluminum chassis provides structural rigidity and thermal stability, supporting long-term operational consistency in ambient temperatures ranging from 5 °C to 40 °C and up to 100 % relative humidity.
Key Features
- IP66-rated enclosure for dust-tight and high-pressure water jet resistance—validated for deployment in washdown zones, outdoor enclosures, and corrosive industrial settings.
- Bidirectional speed control from 0.1 to 265 rpm with 0.1 rpm resolution, enabling fine-tuned adaptation to viscosity shifts and pressure variations across tubing configurations.
- Triple-layer safety architecture: hardware-based lid-open interlock, optional optical or capacitive leak detection, and non-volatile power-loss memory requiring manual confirmation before resumption—fully aligned with ALARP (As Low As Reasonably Practicable) risk mitigation principles.
- Industrial-grade 4.3-inch TFT-LCD interface with dual-language support (English/Chinese), real-time clock, and intuitive navigation for rapid configuration of flow, volume, or calibration modes.
- Comprehensive I/O flexibility: isolated analog inputs (0–10 V / 4–20 mA) for external setpoint modulation; analog outputs for closed-loop monitoring; digital triggers for PLC-synchronized start/stop/direction; and three programmable relays for alarm signaling or auxiliary actuation.
- Modular communication stack supporting RS485 (Modbus RTU), optional TCP/IP Ethernet, and Profibus DP—enabling seamless integration into DCS, SCADA, and MES platforms without protocol gateways.
Sample Compatibility & Compliance
The dPOFLEX GP01 accommodates standard peristaltic tubing sizes from 0.5 mm to 16 mm inner diameter, compatible with silicone, Viton®, EPDM, and PharmPure® materials—certified for USP Class VI, FDA CFR 21 Part 177.2600, and EU 10/2011 compliance where applicable. Optional low-pulse pump heads reduce flow pulsation below ±1.5 % (measured at 100 mL/min with 3.2 mm ID tubing), critical for sensitive photometric or electrochemical detection systems. The device meets CE and UKCA marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU), with full test reports issued by TÜV SÜD. For regulated pharmaceutical and biotech applications, it supports IQ/OQ documentation packages and satisfies audit-trail requirements per FDA 21 CFR Part 11 through electronic signature-enabled user authentication and immutable event logging.
Software & Data Management
No proprietary software installation is required for basic operation; all configuration and monitoring occur via the onboard HMI or external PLC signals. However, optional PC-based configuration tools provide extended diagnostics—including historical flow deviation analysis, pump head wear trending, and tubing lifetime estimation based on cumulative compression cycles. All logged events (e.g., lid open, leak alert, mode change, parameter edits) are time-stamped, user-attributed, and stored in non-volatile memory with configurable retention (default: 10,000 entries). Audit trails include cryptographic hashing to prevent tampering and export in CSV or PDF formats compliant with GLP/GMP data integrity expectations.
Applications
- Continuous reagent delivery in online water quality analyzers (e.g., COD, NH₃-N, phosphate sensors)
- Accurate dosing of pH adjusters, coagulants, or biocides in municipal and industrial wastewater treatment plants
- Media and feedstock transfer in single-use bioreactors and perfusion cell culture systems
- Automated sample introduction in ICP-OES, IC, and TOC analyzers requiring pulse-free flow stability
- GMP-compliant liquid handling in API synthesis lines, including solvent recovery and intermediate transfer
- Calibration fluid circulation in metrology labs performing volumetric verification per ISO 4064-2
FAQ
What tubing sizes are supported?
The dPOFLEX GP01 accepts tubing with inner diameters from 0.5 mm to 16 mm, depending on selected pump head configuration.
Is flow calibration traceable to national standards?
Yes—built-in flow calibration mode accepts reference measurements from certified flow meters (e.g., gravimetric or Coriolis standards), storing correction factors with timestamped audit records.
Can the pump operate unattended for extended periods?
It supports fully autonomous quantitative dispensing (up to 9999 cycles or infinite loop), with integrated safeguards including lid-open shutdown, leak detection, and mandatory manual restart after power interruption.
Does it meet FDA 21 CFR Part 11 requirements for electronic records?
Yes—when configured with user authentication and audit-trail logging enabled, it fulfills electronic signature, record retention, and change-control provisions specified in Part 11 Subpart B.
What certifications are included with shipment?
CE Declaration of Conformity, UKCA Certificate (TÜV SÜD), and test reports covering EN 61010-1, EN IEC 61010-2-201, and EN IEC 61000-6-2/6-4 are provided as standard documentation.
