MZR-7208 Precision Micro-Infusion Pump

Overview

The MZR-7208 Precision Micro-Infusion Pump is a high-accuracy, digitally controlled peristaltic and piston-based infusion system engineered for repeatable, low-volume liquid delivery in regulated laboratory, pharmaceutical, and industrial process environments. Unlike standard syringe pumps or volumetric dispensers, the MZR-7208 integrates a high-torque DC servo motor with precision-machined fluid path components to achieve stable flow rates across a wide viscosity spectrum—from aqueous buffers and organic solvents (e.g., methanol) to viscous adhesives, inks, coatings, and lubricants. Its operational principle combines positive displacement via calibrated rotary motion (for peristaltic mode) and linear displacement with closed-loop position feedback (for piston mode), enabling traceable, gravimetrically verifiable dosing compliant with ISO 8536-4 and ASTM D1298 standards for volumetric accuracy in medical and analytical applications.

Key Features

• DC servo motor-driven actuation delivering high torque at low rotational speeds—ensuring smooth, pulse-free flow even at sub-mL/min rates
• Adjustable flow range: 0.048–288 mL/min, programmable in 0.001 mL/min increments via front-panel keypad or remote interface
• Modular pump head design supporting both peristaltic tubing (ID 0.5–3.2 mm) and precision glass/metal syringes (1–100 mL capacity)
• IP54-rated enclosure with chemical-resistant housing materials (316 stainless steel fittings, PTFE/PFA fluid-contact surfaces)
• Integrated real-time pressure monitoring with automatic stall detection and over-pressure cutoff (max. 6 bar continuous, 10 bar peak)
• Compliance-ready firmware architecture supporting audit trail logging, user access levels, and electronic signature capability per FDA 21 CFR Part 11 requirements

Sample Compatibility & Compliance

The MZR-7208 accommodates a broad range of chemically diverse media, including but not limited to: sterile saline and dextrose solutions, ethanol/water mixtures, methanol, isopropanol, mineral oils, silicone-based lubricants, UV-curable acrylates, epoxy resins, waterborne and solvent-based inks, and pigment-dispersed coating formulations. All wetted parts meet USP Class VI biocompatibility criteria and EU Regulation (EC) No. 1935/2004 for materials intended to contact medicinal products. The device conforms to IEC 61000-6-2 (EMC immunity) and IEC 61000-6-3 (EMC emission) standards, and is CE-marked under the Medical Devices Regulation (MDR 2017/745) Annex II Class IIa for infusion control applications requiring dose accuracy ≤ ±1.5% of setpoint (as validated per ISO 60601-2-24).

Software & Data Management

The pump supports native RS-232, USB-C, and optional Ethernet (TCP/IP) communication protocols. HNPM’s proprietary PumpControl Suite v4.2 provides full remote configuration, multi-pump synchronization, method storage (up to 99 protocols), and time-stamped event logging—including flow deviation alerts, motor load anomalies, and tubing wear diagnostics. Data export is available in CSV and PDF formats with embedded digital signatures; all records retain full GLP/GMP traceability, including operator ID, timestamp, calibration history, and revision-controlled method parameters. Audit trails are immutable and support retrospective review during regulatory inspections.

Applications

• Clinical research infusion studies requiring precise titration of vasoactive agents or analgesics
• Pharmaceutical R&D: formulation stability testing, excipient compatibility screening, and small-volume API dosing in dissolution apparatus
• Microfluidic device priming and reagent loading in diagnostic cartridge manufacturing
• Automated adhesive dispensing for medical device assembly (e.g., catheter bonding, sensor encapsulation)
• Controlled ink deposition in printed electronics prototyping and biosensor fabrication
• Calibration fluid delivery in ISO/IEC 17025-accredited metrology labs performing volumetric instrument verification

FAQ

Is the MZR-7208 certified for use in human clinical infusion settings?

Yes—it carries CE marking under MDR 2017/745 Class IIa and is validated for use in hospital-based investigational drug administration when operated within defined flow and pressure limits per EN ISO 60601-2-24.
Can the pump handle shear-sensitive biologics without degradation?

When configured with low-shear peristaltic heads and appropriate tubing (e.g., PharMed BPT), it maintains protein integrity for monoclonal antibodies and recombinant enzymes, as verified by SEC-HPLC and activity assays.
What maintenance intervals are recommended for long-term GMP compliance?

Daily visual inspection of tubing and seals; monthly torque verification of drive mechanism; annual recalibration traceable to NIST-certified mass standards—documented in the included Maintenance Logbook.
Does the system support integration into SCADA or MES platforms?

Yes—via Modbus RTU over RS-485 or OPC UA over Ethernet, enabling bidirectional data exchange with Siemens PCS7, Rockwell FactoryTalk, and Werum PAS-X systems.
