Sanotac MP-1006-C Stainless Steel Constant-Flow High-Pressure Metering Pump for Polypropylene Meltblown Specialty Resin Development

Overview

The Sanotac MP-1006-C is a precision-engineered, stainless steel constant-flow high-pressure metering pump designed specifically for controlled liquid reagent delivery in polymer modification processes—particularly the development and pilot-scale production of polypropylene (PP) meltblown specialty resins. Operating on positive displacement piston technology with dual ceramic-sapphire check valves and a 316L stainless steel fluid path, the MP-1006-C ensures stable, pulse-dampened flow under sustained backpressure up to 6 MPa. Its core application lies in the precise metering of thermally sensitive organic peroxides—such as di-tert-butyl peroxide (DTBP)—into molten PP during extrusion compounding. This enables reproducible molecular weight reduction and narrow molecular weight distribution control, directly governing melt mass-flow rate (MFR) and rheological performance critical for consistent meltblown web formation.

Key Features

• High-accuracy volumetric delivery: Flow range 0.1–100.0 mL/min with ±1% accuracy and ≤1% repeatability—validated across operating pressure gradients up to 6 MPa.
• Chemically inert wetted materials: 316L stainless steel body, sapphire ball seats, and zirconia ceramic plungers ensure compatibility with aggressive organic peroxides, halogenated solvents, and high-temperature process streams.
• Low-pressure pulsation design: Integrated damping geometry and optimized valve dynamics limit pressure ripple to ≤0.2 MPa—minimizing flow disturbance in sensitive extrusion feed zones.
• Dual communication architecture: Standard RS232 interface supports integration with PLCs, SCADA systems, or custom lab automation platforms; optional RS485/422 enables multi-pump daisy-chaining and industrial fieldbus compliance.
• Regulatory-ready firmware: Supports audit-trail logging (via external host), parameter lockout, and user-access levels—facilitating alignment with GLP, GMP, and FDA 21 CFR Part 11 data integrity requirements when deployed in regulated R&D environments.

Sample Compatibility & Compliance

The MP-1006-C is validated for continuous duty with low-viscosity, thermally labile liquid additives including DTBP, dicumyl peroxide (DCP), and other alkyl peroxides used in controlled rheology PP synthesis. Its 316L/sapphire/zirconia fluid path meets ASTM F899-22 standards for corrosion resistance in chemical metering applications. The pump conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) for electromagnetic compatibility in laboratory and pilot plant settings. CE marking is applied per Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.

Software & Data Management

While the MP-1006-C operates as a standalone analog/digital hybrid instrument, its embedded firmware supports bidirectional command protocols—including Sanotac’s native ASCII command set and standard Modbus RTU—enabling seamless integration into LIMS, MES, or custom Python/Matlab-based process monitoring suites. Flow setpoints, runtime logs, error codes, and pressure feedback (via optional external transducer input) can be timestamped and exported in CSV format. For traceability-critical workflows, external host systems may implement electronic signatures, change control logs, and versioned calibration records—fully compliant with ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) principles.

Applications

• Rheology-controlled PP resin development: Precise DTBP dosing during twin-screw extrusion to target MFR values from 1000 to 1800 g/10 min (230 °C/2.16 kg) for medical-grade meltblown filtration media.
• Lab-scale polymer functionalization: Delivery of crosslinkers, compatibilizers, or flame retardants into reactive extrusion lines with sub-milliliter dosing resolution.
• Microreactor & continuous flow chemistry: Stable reagent feeding into chip-based or tubular reactors where pulse-free flow and chemical inertness are mandatory.
• QC/QA instrumentation support: Integration with FTIR, GPC, or capillary rheometers requiring calibrated solvent or standard solution delivery at constant pressure.
• Pharmaceutical excipient processing: Controlled addition of plasticizers or solubilizers into hot-melt extrusion (HME) formulations under cGMP-aligned engineering controls.

FAQ

What is the maximum allowable inlet pressure for the MP-1006-C?
The pump is designed for atmospheric or slightly pressurized inlet conditions; maximum recommended inlet pressure is +0.2 MPa (gauge) to prevent seal extrusion and valve misalignment.
Can the MP-1006-C be used with viscous solutions above 500 cP?
No—it is optimized for low-to-medium viscosity liquids (<200 cP at operating temperature); higher viscosities require pre-heating, dilution, or selection of a gear or progressive cavity pump variant.
Is calibration certification included with shipment?
A factory calibration report (traceable to NIST-certified flow standards) is provided; ISO/IEC 17025-accredited third-party calibration is available upon request.
How does the pump handle thermal expansion of DTBP during extended operation?
The pump head incorporates thermal isolation between motor housing and fluid chamber; ambient cooling fins and optional air-cooling kits mitigate heat soak, preserving DTBP stability and flow linearity over 8-hour shifts.
Does Sanotac offer validation documentation for GMP environments?
Yes—IQ/OQ templates, DQ support files, and URS alignment documentation are available under NDA for pharmaceutical and medical device clients.
