LongerPump 80-Series ODM Peristaltic Pump with Fixed-Speed Options and Up to 1342 mL/min Flow Rate

Overview

The LongerPump 80-Series ODM Peristaltic Pump is an industrial-grade, fixed-speed peristaltic pumping solution engineered for reliable, contamination-free fluid transfer in analytical instrumentation, bioprocessing skids, chemical dosing systems, and laboratory automation platforms. Based on the principle of positive displacement via roller compression of flexible tubing, this series delivers precise volumetric flow without internal valves, seals, or wetted metal components—ensuring inherent fluid isolation and minimizing cross-contamination risk. Designed for original design manufacturing (ODM) integration, the 80-Series supports standardized mechanical interfaces, modular pump head mounting, and configurable electrical inputs (DC 12V/24V or AC 220V/50Hz), enabling seamless incorporation into OEM equipment where regulatory traceability, long-term operational stability, and serviceability are critical.

Key Features

• Fixed-speed architecture with factory-calibrated motor assemblies—eliminates speed control circuitry complexity and improves long-term repeatability under constant-load conditions.
• Dual power architecture: DC variants (12V/24V, 40W) employ high-torque brushed gearmotors with thermal protection; AC variant (220V, 40W, 50Hz) utilizes a low-noise, capacitor-run induction gearmotor rated for 5000-hour continuous operation.
• Modular mounting system: Available in panel-mount (D4 suffix) and baseplate-mount (D3 suffix) configurations, accommodating standard DIN-rail or custom chassis integration with M4 threaded inserts.
• Multi-pump-head compatibility: Supports eight distinct pump head families—including DG15-24, YZ1515x, YZII25, BZ15-13 series, BZ25, FG15-13, and FG25-13—enabling optimization for pressure capability (up to 2.5 bar), flow range, and tubing wear life.
• Tubing flexibility: Accepts industry-standard peristaltic tubing sizes from #13 to #25 (inner diameters 1.6–3.2 mm), compatible with silicone, Norprene®, Viton®, and Tygon® chemistries—validated per ISO 10993-5 cytotoxicity guidelines for non-invasive applications.
• Robust mechanical construction: Housing fabricated from reinforced ABS with IP20-rated enclosure; roller trains hardened to ≥58 HRC; shaft runout <0.05 mm for consistent occlusion and reduced tubing fatigue.

Sample Compatibility & Compliance

The 80-Series is validated for use with aqueous buffers, organic solvents (e.g., ethanol, isopropanol), dilute acids/bases (pH 2–12), and sterile cell culture media—provided tubing material compatibility is confirmed per manufacturer specifications. It meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). While not certified for intravenous or implantable device use, its design aligns with general principles of ISO 13485:2016 clause 7.5.1 (production and service provision control) when integrated into Class I or IIa medical devices. For pharmaceutical applications, tubing selection must comply with USP and extractables/leachables testing; pump head torque profiles are documented to support IQ/OQ protocols per GAMP 5 Annex 11 expectations.

Software & Data Management

As a fixed-speed, analog-driven device, the 80-Series does not incorporate embedded firmware or digital communication interfaces (e.g., RS-485, CAN, or Modbus). Its operation is fully deterministic: flow rate is governed solely by motor speed, roller geometry, and tubing inner diameter—enabling direct correlation between input voltage and volumetric output without calibration drift. For traceable operation in GLP/GMP environments, users may integrate external tachometer feedback or flowmeter verification (e.g., Coriolis or ultrasonic) to log runtime, cumulative volume, and deviation alerts. All mechanical and electrical specifications are documented in the Factory Test Report (FTR), supplied with each unit, supporting audit readiness per FDA 21 CFR Part 11 when paired with validated electronic lab notebook (ELN) systems.

Applications

• Continuous feed in HPLC mobile phase delivery modules (low-pressure solvent blending).
• Reagent dosing in automated immunoassay analyzers and clinical chemistry platforms.
• Media circulation in single-use bioreactors and perfusion cell culture systems (≤5 L working volume).
• Waste aspiration and wash buffer delivery in ELISA washers and microplate handlers.
• Chemical metering in water quality monitoring stations (e.g., nitrate, phosphate, chlorine reagent addition).
• Calibration fluid transport in field-deployable gas chromatography preconcentrators.

FAQ

Is the 80-Series suitable for sterile or aseptic processing?
Yes—when paired with gamma-sterilizable tubing (e.g., PharMed® BPT or C-Flex® SD-80) and installed in ISO Class 5–7 environments, provided the pump head and housing undergo validated cleaning procedures (e.g., VHP or 70% IPA wipe-down) between batches.
Can flow rate be adjusted in-field without hardware modification?
No—speed is fixed per model. Flow adjustment requires either changing tubing size, selecting a different pump head, or substituting the motor assembly. Variable-speed operation necessitates external PWM or VFD control, which is outside the 80-Series design scope.
What is the maximum backpressure tolerance across pump head options?
Maximum sustainable backpressure ranges from 1.2 bar (DG15-24 with #16 tubing) to 2.5 bar (FG25-13 with #17 tubing), measured at rated speed and ambient temperature. Exceeding these values accelerates tubing wear and may cause slippage.
Does LongerPump provide pump head torque specifications for validation purposes?
Yes—torque curves (Nm vs. speed) and occlusion force data (N per roller) are included in the Technical Dossier supplied with ODM orders, supporting mechanical integration and FMEA analysis.
Are replacement motors and pump heads available as spare parts?
Yes—full-service spares catalog includes motors (with matching part numbers), pump heads, roller assemblies, and mounting brackets, all stocked with ≥18-month shelf life and RoHS-compliant documentation.
