LongerPump 90-2 Series ODM Peristaltic Pump

Overview

The LongerPump 90-2 Series ODM Peristaltic Pump is an industrial-grade, fixed-speed peristaltic pumping solution engineered for high-reliability fluid transfer in analytical instrumentation, bioprocessing, chemical dosing, and laboratory automation systems. Based on the positive displacement principle of peristalsis—where rollers compress flexible tubing to generate unidirectional flow—the 90-2 series delivers consistent, pulse-dampened flow without fluid contact with mechanical components. Its robust architecture integrates a precision-machined pump head, high-torque geared motor, and thermally stable housing, enabling continuous operation under demanding environmental conditions. Designed specifically for original design manufacturer (ODM) integration, the series supports seamless mechanical and electrical embedding into third-party equipment, including liquid handling workstations, chromatography auxiliary modules, fermentation feed systems, and environmental monitoring analyzers.

Key Features

• Fixed-speed operation across 12 discrete RPM configurations (166–500 rpm), optimized for repeatable volumetric delivery in closed-loop process control;
• Dual power architecture: selectable DC 12 V / 24 V (90 W) or AC 220 V (90 W) input, supporting global power infrastructure compliance;
• Two standardized mounting options—panel-mount and baseplate-mount—facilitating rapid integration into OEM enclosures or benchtop assemblies;
• High-durability geared motor with thermal protection circuitry; service life rated from 2,000 to 5,000 hours depending on load profile and ambient temperature;
• Calibrated flow performance validated using industry-standard silicone or Tygon®-type peristaltic tubing (sizes 73# and 82#); maximum flow up to 7645 mL/min at 500 rpm with 82# tubing;
• Flow accuracy maintained within ±10% under steady-state conditions, meeting baseline requirements for non-critical metering applications governed by ISO 8573-1 and ASTM D341;
• Operating envelope certified for 0–40 °C ambient temperature and <80% relative humidity (non-condensing), aligning with IEC 60529 IP20 enclosure classification.

Sample Compatibility & Compliance

The 90-2 series accommodates standard peristaltic tubing dimensions, with validated performance for inner diameters ranging from 1.6 mm (73#) to 3.2 mm (82#). Tubing material compatibility includes silicone, Viton®, Norprene®, and PharmPure® formulations—enabling use with aqueous buffers, organic solvents, mild acids/bases, and shear-sensitive biological media. While not certified for sterile or Class 100 cleanroom operation out-of-the-box, the pump’s tube-only wetted path complies with USP Class VI biocompatibility testing prerequisites when paired with appropriate tubing. Electrical safety conforms to GB 4793.1–2007 (equivalent to IEC 61010-1:2010), and electromagnetic compatibility meets EN 61326-1:2013 for laboratory and industrial environments.

Software & Data Management

As a fixed-speed analog pump, the 90-2 series does not incorporate embedded firmware, digital interfaces (e.g., RS-485, CAN, or USB), or onboard data logging. It operates via direct voltage supply and is intended for integration into host-controlled systems. OEM partners may implement external control logic—including PWM speed modulation (where applicable), relay-based start/stop sequencing, or PLC-driven duty cycling—using standard 24 VDC control signals. For regulatory environments requiring audit trails (e.g., GLP, GMP, or FDA 21 CFR Part 11), system-level validation must be performed at the integrated instrument level, as the pump itself provides no electronic recordkeeping or user authentication capabilities.

Applications

• Continuous reagent delivery in automated wet-chemistry analyzers and ion chromatography auxiliary systems;
• Media and feedstock transfer in single-use bioreactors and benchtop fermenters;
• Sampling loop priming and waste evacuation in online water quality monitors (e.g., COD, TOC, nitrate analyzers);
• Low-shear perfusion of cell cultures in microfluidic platforms and organ-on-chip devices;
• Chemical dosing in wastewater treatment pilot skids and electroplating bath replenishment systems;
• Integration into CE-IVD or RUO diagnostic platforms where precise, contamination-free fluid routing is required.

FAQ

Is the 90-2 series suitable for sterile or pharmaceutical manufacturing environments?
No—this is a non-sterilizable, open-frame peristaltic pump intended for general-purpose fluid handling. Sterile applications require validated, autoclavable, or gamma-irradiated pump modules with documented material traceability and particulate shedding data.
Can flow rate be adjusted dynamically during operation?
No—the 90-2 series offers fixed-speed variants only. Variable speed control requires selection of a different model family (e.g., LongerPump BT100-2J or WP1000 series) with analog/digital speed input capability.
What tubing certifications are supported?
The pump is mechanically compatible with tubing compliant with ISO 3308, USP , and FDA 21 CFR 177.2600. Final biocompatibility and extractables profiling must be verified by the end-user using their selected tubing lot.
Does LongerPump provide OEM documentation packages?
Yes—complete mechanical drawings (STEP, PDF), electrical schematics, mounting templates, and RoHS/REACH declarations are available under NDA for qualified ODM partners.
What is the warranty coverage for embedded units?
Standard warranty is 12 months from shipment date. Extended warranties up to 36 months are available for volume OEM agreements, subject to agreed-upon service level terms and failure mode analysis protocols.
