Overview
The Cole-Parmer Model 07012 Miniature Gear Pump is an engineered solution for precise, low-flow fluid transfer in space-constrained and mission-critical laboratory and OEM applications. Utilizing positive displacement gear pumping technology, it delivers consistent volumetric flow independent of backpressure within its operational envelope—making it ideal for metering, recirculation, dosing, and closed-loop system integration. Designed for reliability under continuous operation, the pump features a compact, modular architecture with chemically resistant wetted materials—including Delrin® acetal housing, 304 stainless steel gears and shafts, Nitrile (NBR) elastomer seals, and PTFE components—ensuring compatibility with a broad range of solvents, aqueous solutions, oils, and mild corrosives up to 93°C (200°F). Its sealed, brushless design eliminates commutator wear and supports stable performance across variable load conditions.
Key Features
- Five standardized configurations (07012-00, -02, -20, -30, -32) optimized for distinct power inputs (115 VAC, 230 VAC, or 12 VDC) and flow requirements (1000–2520 mL/min)
- Positive displacement gear mechanism ensures repeatable flow accuracy and minimal pulsation—critical for analytical instrument feed systems and process control loops
- Maximum pressure capability of 21 psi (for 12 VDC variant) and 10 psi (for AC variants), enabling operation against moderate system resistance without flow deviation
- 3/16″ barbed inlet/outlet ports facilitate rapid, leak-resistant connection to Tygon®, Viton®, or silicone tubing using standard hose clamps
- Self-priming capability with 4-inch dry lift and 10-foot wet lift supports flexible installation in benchtop, cabinet-integrated, or mobile platforms
- Continuous-duty rating with thermally stable motor windings and passive heat dissipation—validated for unattended 24/7 operation in controlled environments
- Compact footprint: dimensions range from 3.44″ × 3.19″ × 3.63″ (OEM variants) to 5.63″ × 2.63″ × 3.75″ (enclosed variants with integrated switch and grounded cord)
Sample Compatibility & Compliance
The Model 07012 is compatible with Newtonian and mildly shear-thinning fluids up to 200 cP viscosity, including water, buffer solutions, ethanol, isopropanol, light mineral oils, and glycerol/water mixtures. Its material set complies with USP Class VI biocompatibility standards for plastics (Delrin®) and meets FDA 21 CFR 177.2470 requirements for food-contact polymers. While not certified for explosive atmospheres, the pump is suitable for use in general laboratory settings per ANSI Z9.5 ventilation guidelines and conforms to IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards. It is not intended for handling abrasive slurries, high-vapor-pressure solvents above flash point, or fluids containing particulates >50 µm.
Software & Data Management
As a standalone electromechanical device, the Model 07012 operates without embedded firmware or digital communication interfaces. Flow rate is governed solely by input voltage frequency (for AC models) or DC voltage level (for 12 VDC model), enabling seamless integration into analog-controlled systems via variable transformers or programmable power supplies. For traceability in GLP/GMP-regulated workflows, users may pair the pump with external flow meters (e.g., Coriolis or thermal mass flow sensors) and log data via SCADA or LabVIEW-compatible DAQ systems. No software licensing, driver installation, or cybersecurity configuration is required—reducing validation burden in regulated QC laboratories.
Applications
- Reagent delivery in automated titrators, spectrophotometers, and HPLC auxiliary solvent lines
- Recirculation in small-volume temperature-controlled baths and electrochemical cells
- OEM integration into portable diagnostic analyzers, environmental monitoring stations, and microfluidic test benches
- Low-shear transfer of cell culture media, fermentation broths, and pharmaceutical suspensions where foaming must be minimized
- Calibration fluid circulation in pressure transducer test rigs and viscosity reference systems
- Benchtop solvent recovery loops and distillation condensate return systems
FAQ
What is the maximum allowable fluid temperature for continuous operation?
The pump is rated for continuous duty at fluid temperatures up to 93°C (200°F); sustained exposure above this threshold may accelerate elastomer compression set and reduce seal service life.
Can this pump handle abrasive or particulate-laden fluids?
No—particles larger than 50 µm may cause gear tooth scoring or port occlusion; filtration to ≤25 µm is strongly recommended for any fluid containing suspended solids.
Is the pump self-priming, and what are the practical limits for suction lift?
Yes, it achieves 4 inches of dry lift and up to 10 feet of wet lift under optimal conditions (viscosity <50 cP, ambient temperature, no vapor lock); lift performance decreases significantly above 100 cP.
Does Cole-Parmer provide calibration certificates or flow verification reports?
Factory calibration is performed per internal QA procedures; however, NIST-traceable flow certification is available as a value-added service upon request prior to shipment.
What maintenance intervals are recommended for extended service life?
Under clean-fluid conditions, inspection of seals and gear endplay is advised every 5,000 operating hours; replacement kits (seals, bearings, and O-rings) are stocked and cross-referenced by part number in the technical manual.
