LongerPump TH15 OEM AC Synchronous Precision Peristaltic Pump

Overview

The LongerPump TH15 OEM AC Synchronous Precision Peristaltic Pump is an industrial-grade, fixed-speed but multi-step selectable peristaltic drive engineered for continuous, low-pulsation fluid transfer in analytical, bioprocessing, and laboratory automation systems. Based on the principle of positive displacement via roller compression of elastomeric tubing, the TH15 employs a high-torque AC synchronous motor coupled with a precision gear reduction mechanism to deliver stable rotational output across six discrete speed settings (5–110 rpm). Unlike variable-frequency drives or brushless DC alternatives, this architecture ensures inherent speed stability without closed-loop feedback—ideal for applications where long-term repeatability and immunity to voltage fluctuation are critical. Its design conforms to fundamental peristaltic pump performance criteria defined in ISO 8536-4 (infusion equipment) and aligns with mechanical safety expectations outlined in IEC 61000-6-2 (EMC immunity) and IEC 60601-1 (general requirements for medical electrical equipment), though it is classified as a component-level OEM device—not a finished medical instrument.

Key Features

• AC synchronous motor with integrated gear reduction delivers consistent torque and minimal speed drift under varying load conditions
• Six factory-calibrated speed settings (5, 15, 30, 50, 60, 110 rpm) selected via external jumper configuration or OEM control interface
• Panel-mountable mechanical design with standardized G-series chassis interface (e.g., G5-A102, G110-A102) for seamless integration into custom enclosures or analytical platforms
• Optimized for use with industry-standard peristaltic tubing sizes (13#, 14#, 16#, 19#, 25#), supporting flow ranges from 0.1 to 184 mL/min depending on tubing ID and fluid viscosity
• Robust aluminum alloy housing with IP20-rated ingress protection; thermally stable operation across 0–40 °C ambient range
• No internal electronics or microcontroller—eliminates firmware dependencies, EMI susceptibility, and obsolescence risk in long-lifecycle instrumentation

Sample Compatibility & Compliance

The TH15 is compatible with all common peristaltic tubing materials certified for chemical resistance and biocompatibility—including Pharmed BPT, Norprene, Viton, and silicone—enabling safe handling of aqueous buffers, organic solvents, cell culture media, and mild acids/bases. While the pump itself does not carry CE, UL, or FDA clearance as a standalone device, its mechanical architecture supports system-level compliance when integrated into instruments subject to ISO 13485, FDA 21 CFR Part 11 (when paired with audit-trail-capable host software), and GLP/GMP documentation workflows. Tube selection must be validated per application-specific chemical compatibility charts and pressure/flow requirements. Maximum backpressure tolerance is determined by tubing wall thickness and occlusion setting—not specified in isolation due to system-dependent variables.

Software & Data Management

As a purely electromechanical OEM component, the TH15 operates without embedded firmware, communication protocols (e.g., RS-485, Modbus), or digital control interfaces. Speed selection is achieved via hardware jumpers or external relay/toggle switching—making it suitable for legacy or safety-critical systems requiring deterministic behavior and zero software validation burden. When integrated into larger platforms, speed state and operational runtime can be logged externally via auxiliary dry-contact outputs (optional accessory) or current-sensing circuits. For regulatory environments requiring electronic records, full traceability is maintained through host-system software that logs actuation events, duration, and associated process parameters—consistent with ALCOA+ data integrity principles.

Applications

• Continuous reagent delivery in automated wet chemistry analyzers and ICP-OES sample introduction systems
• Media perfusion in benchtop bioreactors and hollow-fiber cell culture units
• Calibration standard dosing in environmental water quality monitors (e.g., nitrate, phosphate analyzers)
• Low-shear sampling in HPLC autosampler wash stations and fraction collector interfaces
• OEM integration into point-of-care diagnostic platforms requiring silent, non-invasive fluid handling
• Process monitoring loops in food & beverage QC lines (e.g., pH titration, colorimetric assays)

FAQ

Is the TH15 suitable for sterile or USP compounding applications?
No—the TH15 is a non-sterile OEM drive unit. Sterility assurance requires terminal sterilization of the entire fluid path, including tubing and connectors; the pump head must be validated separately per ISO 15223 and AAMI TIR36.
Can I use the TH15 with conductive or abrasive slurries?
Only if tubing material is chemically and mechanically rated for such fluids (e.g., reinforced silicone or fluoropolymer-lined tubing); particulate-laden streams require upstream filtration to prevent premature tube fatigue.
Does LongerPump provide calibration certificates or metrological traceability?
No—speed accuracy (≤±10%) is verified during production against NIST-traceable tachometers, but formal calibration documentation is not supplied unless requested as a custom service with additional lead time and cost.
What maintenance intervals are recommended?
Roller assembly lubrication is not required; periodic visual inspection of tubing compression and roller surface wear is advised every 500 operating hours—or after each tubing replacement cycle.
Is there a version with analog speed control (0–10 V or 4–20 mA)?
Not in the TH15 series. For continuously variable speed, consider the LongerPump BT100-2J or DG series, which support analog/digital input modes and closed-loop RPM feedback.
