HNPM MZR-11558 Corrosion-Resistant Micro-Dosing Peristaltic Pump

Overview

The HNPM MZR-11558 is a high-integrity, corrosion-resistant micro-dosing peristaltic pump engineered for precise, pulse-free fluid handling in aggressive chemical environments. Unlike conventional peristaltic or syringe pumps, the MZR-11558 employs a patented rotary ring-gear displacement principle—eliminating valves, seals, and diaphragms—to deliver continuous, metered flow across a wide viscosity range (0.3–1000 mPa·s). Its core architecture is based on magnetically coupled ceramic drive train components, ensuring full chemical inertness and long-term dimensional stability under sustained exposure to oxidizing acids, reducing alkalis, halogenated solvents, and high-concentration brines. Designed and manufactured in Germany to DIN EN ISO 9001 standards, the pump meets critical requirements for use in GMP-compliant pilot-scale flow chemistry, continuous API synthesis, and automated analytical sample introduction where material compatibility and dosing reproducibility are non-negotiable.

Key Features

• Chemically inert wetted path constructed from Alloy C22 (DIN 2.4602), sintered silicon carbide (SSiC), alumina (Al₂O₃), and zirconia (ZrO₂) ceramics—resistant to HF, aqua regia, hot concentrated HNO₃, NaOH up to 50%, and chlorinated hydrocarbons.
• Magnetic coupling using NdFeB (neodymium-iron-boron) permanent magnets ensures hermetic separation between drive motor and fluid chamber—zero leakage risk and no dynamic seal degradation.
• Brushless DC motor with integrated high-resolution encoder (500 ppr) and Hall-effect sensor feedback enables closed-loop speed control with ±0.2% repeatability over full rpm range (1–6000 rpm).
• Low-pulsation operation (<1% CV) achieved via optimized gear geometry and rigid ceramic rotor/stator alignment—critical for UV-Vis detection, calorimetric monitoring, and residence-time-sensitive reactions.
• Thermal protection via embedded PTC resistor (6-element network) and ambient temperature monitoring (−5 to +40 °C standard; extended to +100 °C with optional thermal shielding and FFKM variant seals).
• Modular electrical interface: 6-pin motor connector + 12-pin encoder/Hall sensor header; 3 m shielded cable pre-wired for industrial PLC integration (IEC 61131-3 compatible).

Sample Compatibility & Compliance

The MZR-11558 is validated for contact with Class 1–3 corrosive media per ASTM D1384 and ISO 16232 cleanliness standards. Its wetted materials comply with USP Class VI biological safety requirements and FDA 21 CFR Part 11 data integrity guidelines when operated with HNPM’s certified control software. The pump supports GLP/GMP audit trails through timestamped encoder logs and motor current profiling. Optional configurations meet ATEX Zone 1 (II 2G Ex db IIB T4 Gb) and IECEx certification for hazardous area deployment. All fluidic interfaces conform to ISO 2858 (NPT) and DIN 259/2999 sealing specifications.

Software & Data Management

HNPM provides the PumpControl Suite v4.2—a Windows-based configuration and monitoring application supporting RS-485 (Modbus RTU), EtherCAT, and analog 0–10 V / 4–20 mA control modes. The software enables real-time flow calibration against gravimetric reference standards (ASTM E2706), automatic viscosity compensation curves, and dose logging with digital signature authentication. Audit trail functionality complies with 21 CFR Part 11 Annex 11 requirements, including user role management, electronic signatures, and immutable event history export (CSV/XML). Firmware updates are delivered via signed .hex packages with SHA-256 verification.

Applications

• Continuous-flow synthesis of pharmaceutical intermediates under acidic or basic catalytic conditions (e.g., nitration, sulfonation, hydrogenation).
• Automated reagent addition in microreactor arrays for kinetic studies (residence time < 5 s) requiring sub-milliliter precision.
• In-line dilution and standard preparation for ICP-MS and IC analysis of high-salinity environmental samples.
• Corrosive electrolyte dosing in electrochemical cell testing (e.g., PEM fuel cells, Li–S battery slurry processing).
• High-purity solvent delivery in semiconductor wet bench processes (SC1, SC2, BOE formulations).
• On-site calibration fluid transfer in field-deployable gas chromatography systems exposed to H₂S or Cl₂.

FAQ

What certifications does the MZR-11558 hold for use in regulated pharmaceutical manufacturing?

The base unit complies with CE Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. With optional firmware and documentation package, it achieves qualification readiness for FDA 21 CFR Part 11 and EU Annex 11 compliance.
Can the pump handle slurries or particles?

It is not designed for abrasive particulates or suspended solids >50 µm; however, with upstream filtration (5 µm SS mesh) and reduced rpm, it reliably doses stabilized colloidal suspensions (e.g., catalyst nanoparticles in ethylene glycol).
Is remote monitoring supported over Ethernet/IP or OPC UA?

Yes—via optional EtherCAT master interface or third-party gateway (e.g., HMS Anybus); native OPC UA support is available in PumpControl Suite v5.0 (Q3 2025 release).
What maintenance intervals are recommended for continuous 24/7 operation?

Ceramic components require no scheduled replacement; annual verification of encoder linearity and motor winding resistance is advised per ISO 13374 condition monitoring standards.
Does HNPM offer custom wetted material configurations for niche chemistries?

Yes—custom ZrO₂-coated SS316L housings, tungsten carbide rotors, and Kalrez® 8500-grade FFKM seals are available under NDA with lead times of 12–16 weeks.
