Cole-Parmer Model 07012-02 Miniature Gear Pump

Overview

The Cole-Parmer Model 07012-02 is a compact, 12 VDC-powered miniature gear pump engineered for precise, low-flow fluid transfer in analytical instrumentation, microfluidic systems, and laboratory automation platforms. Based on positive displacement rotary gear technology, it delivers consistent volumetric flow across variable backpressure conditions up to 10 psi (0.69 bar), with minimal pulsation and high repeatability. Its brushless DC motor ensures stable speed control and extended service life under continuous operation—critical for unattended or integrated applications such as reagent delivery in autosamplers, peristaltic-free solvent transfer in HPLC auxiliary loops, or controlled dosing in bioprocess monitoring systems. Designed for compatibility with chemically aggressive but particle-free liquids—including aqueous buffers, organic solvents (e.g., methanol, acetonitrile), and mild acids/bases—the pump operates within a thermal envelope of up to 93°C, supporting temperature-sensitive workflows without performance degradation.

Key Features

• Compact footprint (under 4.5″ L × 2.8″ W × 3.1″ H) optimized for OEM integration and benchtop space constraints
• Brushless DC motor with electronic speed regulation enables analog or PWM-based flow modulation (0–100% range)
• Self-priming capability with 3.0 m wet suction lift and 10.2 cm dry lift—ideal for headspace-limited enclosures
• Chemically resistant wetted path: acetal (Delrin®) gears, PTFE seals, nitrile elastomer gaskets, and 304 stainless steel shaft and housing components
• No internal pressure relief valve; intended for use with external pressure monitoring or flow-limiting orifices in closed-loop configurations
• UL/CSA recognized power supply compliance; CE marking available for applicable voltage variants

Sample Compatibility & Compliance

This pump is validated for use with Newtonian fluids up to 200 cP viscosity and zero suspended solids—consistent with ISO 8504-2 and ASTM D1298 specifications for low-particulate liquid handling. It meets material compatibility requirements outlined in USP and for non-implantable device components. While not certified for hazardous location use (e.g., Class I Div 1), its construction adheres to general-purpose industrial safety standards per IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity). For GLP/GMP-regulated environments, the pump supports audit-ready documentation packages including material traceability records, RoHS/REACH declarations, and factory calibration certificates upon request.

Software & Data Management

The 07012-02 operates as a hardware-level actuator and does not include embedded firmware or digital communication interfaces (e.g., RS-485, Modbus, or USB). Flow rate is controlled externally via 0–10 V analog input or 1–10 kHz PWM signal, enabling seamless integration into programmable logic controllers (PLCs), DAQ systems (e.g., National Instruments), or custom LabVIEW- or Python-driven automation frameworks. When deployed in regulated settings, users may configure external data loggers to record voltage input, runtime hours, and system pressure feedback—supporting 21 CFR Part 11-compliant electronic records when paired with validated software and access-controlled audit trails.

Applications

• Low-flow mobile phase delivery in portable or field-deployable chromatography systems
• Reagent metering in clinical chemistry analyzers and point-of-care diagnostic cartridges
• Continuous perfusion in organ-on-chip and microphysiological systems (MPS)
• Calibration standard delivery in gravimetric or volumetric verification protocols (ISO/IEC 17025)
• Controlled solvent recycling in closed-loop extraction or purification modules
• OEM integration into environmental air/water samplers requiring silent, low-power fluid actuation

FAQ

Can this pump handle abrasive or particulate-laden fluids?
No. The 07012 series is strictly rated for clean, solids-free liquids. Particulates exceeding 10 µm will accelerate gear wear and compromise volumetric accuracy.

Is dry-running permissible for short durations?
Dry-run operation is not characterized or recommended. Extended dry cycling may cause rapid thermal buildup and irreversible seal deformation.

What is the expected service life under continuous duty?
Rated for >10,000 hours at nominal load (20°C, 10 cP fluid, 50% speed), assuming proper inlet filtration and ambient temperature ≤40°C.

Are replacement gears or seal kits available separately?
Yes. Genuine Cole-Parmer spare parts—including acetal gear sets (P/N 07012-GEAR), PTFE seal kits (P/N 07012-SEAL), and nitrile O-ring packs (P/N 07012-ORING)—are stocked and ship globally with full traceability.

Does Cole-Parmer provide application-specific validation support?
Yes. Engineering support includes flow curve characterization, chemical compatibility screening reports, and integration schematics—available under NDA for qualified OEM partners.
