Cole-Parmer 75211-17 Console Gear Drive for Micropump® A-Mount Gear Pumps

Overview

The Cole-Parmer 75211-17 Console Gear Drive is a precision-engineered, benchtop motor controller designed specifically for use with Micropump® A-mount gear pump heads. It operates on the principle of constant-speed synchronous motor actuation coupled with analog tachometer feedback and proportional speed regulation, delivering stable rotational output across its full 50–5000 rpm range. This drive unit is not a standalone pump but a dedicated power and control module—optimized for applications requiring smooth, pulseless, bi-directional fluid displacement with high volumetric consistency. Its mechanical architecture integrates a high-torque, low-inertia gearmotor with an internal heat-dissipating aluminum housing, enabling extended duty cycles without thermal derating. Designed for integration into laboratory fluid handling systems—including reagent delivery, solvent recycling, continuous filtration, and chemical dosing—the 75211-17 meets fundamental engineering requirements for repeatability, long-term speed stability, and electrical safety compliance under IEC 61000-6-3 (EMC) and IEC 61010-1 (safety).

Key Features

• Wide 100:1 speed control ratio (50–5000 rpm), adjustable via single-turn front-panel potentiometer for intuitive, analog precision
• Dedicated A-mount interface ensures mechanical and dimensional compatibility with Micropump® series gear pump heads, minimizing alignment error and shaft runout
• Integrated LED status indicator provides immediate visual confirmation of power-on state and operational readiness
• Independent front-panel ON/OFF switch retains last-set speed value across power cycling—eliminating recalibration during routine shutdowns
• DB9 rear-panel connector supports TTL-level remote start/stop commands, enabling synchronization with PLCs, data acquisition systems, or programmable logic controllers
• Compact footprint (7.2 × 9.1 × 5.3 in) and IP22-rated enclosure permit safe deployment in dry, non-hazardous laboratory environments with limited bench space
• 230 VAC input (50/60 Hz) complies with European and international mains standards; internal fuse protection and thermal cutoff safeguard against overcurrent and stall conditions

Sample Compatibility & Compliance

The 75211-17 is validated exclusively for use with Micropump® A-mount gear pump heads—available in stainless steel, PTFE, and PVDF wetted material configurations. It does not support peristaltic, diaphragm, or piston-type pump modules. When paired with an appropriately rated A-mount head (e.g., model 01121-10 or 01121-15), the system achieves flow rates from 0.85 to 5850 mL/min, depending on fluid viscosity (1–1000 cP), pressure differential (< 100 psi), and head geometry. The drive itself carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to UL 61010-1 third edition safety requirements for laboratory equipment. While not intrinsically safe, its IP22 rating permits operation in non-condensing indoor environments compliant with ISO 14644-1 Class 8 cleanroom adjacent zones.

Software & Data Management

This is a hardware-only analog drive with no embedded firmware, network interface, or onboard data logging capability. All speed setpoints and operational states are managed manually or via external TTL-level digital signals. For traceable operation in regulated environments (e.g., GLP or GMP labs), users must implement external recording—such as through a calibrated DAQ system capturing analog voltage output (0–10 VDC proportional to rpm) or discrete relay status. Though lacking FDA 21 CFR Part 11-compliant audit trails natively, the device may be incorporated into validated workflows when paired with compliant supervisory software and documented change control procedures.

Applications

• Continuous low-shear transfer of shear-sensitive biological buffers and cell culture media
• Controlled chemical injection in pilot-scale reaction monitoring systems
• Recirculation loops for inline filtration and ultrafiltration setups
• Calibration fluid delivery in analytical instrument sample introduction modules
• Process validation studies requiring repeatable volumetric throughput across multi-hour runs
• Integration into custom-built OEM fluidic manifolds where compact, reliable DC-equivalent speed control is required

FAQ

Is the 75211-17 compatible with non-Micropump® A-mount pump heads?
No. Mechanical and electrical interfaces are proprietary to Micropump® A-mount specifications. Substitution with non-certified heads voids performance guarantees and may cause mechanical interference or motor overload.
Does this drive support analog speed feedback output?
Yes—via a 0–10 VDC signal proportional to actual motor speed, accessible at the DB9 connector (pin 5), enabling closed-loop verification in external control systems.
Can it operate continuously at 5000 rpm?
Yes, provided ambient temperature remains ≤35°C and the connected pump head is properly lubricated and loaded within its specified pressure/viscosity envelope.
Is there a replacement warranty or service program available?
Cole-Parmer offers a standard 12-month limited warranty covering defects in materials and workmanship. Extended service plans and calibration documentation are available upon request through authorized distributors.
What safety certifications apply to this unit?
It is CE-marked, UL-listed to UL 61010-1, and conforms to IEC 61000-6-3 for electromagnetic compatibility in laboratory settings.
