Tongtian TBP1020S Precision Constant-Flow Parallel-Flow Pump

Overview

The Tongtian TBP1020S is a high-precision, microprocessor-controlled constant-flow parallel-flow pump engineered for continuous, pulse-free liquid delivery in demanding laboratory and pilot-scale applications. Unlike conventional reciprocating piston pumps that inherently generate pressure fluctuations due to cyclic displacement, the TBP1020S employs a synchronized dual-ceramic plunger architecture with sapphire ball check valves and optimized fluidic path geometry to achieve true laminar flow characteristics—minimizing pressure pulsation to ≤ 0.01 MPa across its full operating range (0.1–10.0 mL/min at up to 10.0 MPa). This design principle aligns with ISO 5840-3 and ASTM D3418 standards for steady-state flow instrumentation, making it suitable for applications where flow stability directly impacts analytical integrity or reaction kinetics—such as preparative chromatography, microreactor feeding, and controlled reagent dosing in GLP-compliant synthesis workflows.

Key Features

• Parallel-flow dual-plunger mechanism delivering ultra-low pulsation (≤ 0.01 MPa) and exceptional flow linearity
• Chemically inert wetted path options: 316L stainless steel, pure titanium, PEEK, and PTFE—validated for compatibility with aggressive solvents including concentrated acids, halogenated organics, and supercritical CO₂ co-solvents
• Ceramic plunger rods and sapphire ball valves ensure long-term wear resistance and dimensional stability under sustained high-pressure operation
• Integrated real-time monitoring of setpoint vs. actual pressure and flow rate via high-resolution digital display
• Programmable timer function enabling unattended operation with start/stop scheduling and auto-shutdown protocols
• RS-232/USB interface compliant with Modbus RTU protocol for integration into SCADA systems and LIMS environments
• Self-diagnostic firmware with error logging and alarm thresholds configurable per IEC 61508 functional safety guidelines

Sample Compatibility & Compliance

The TBP1020S supports a broad spectrum of process fluids—from aqueous buffers and organic mobile phases (acetonitrile, methanol, THF) to corrosive reagents (fuming nitric acid, hydrofluoric acid solutions) and viscous polymer melts (up to 500 cP at 25°C). Its modular wetted-material selection (L/T/K/F codes) enables user-defined chemical compatibility mapping per application-specific risk assessment. The pump meets CE marking requirements under the Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. For regulated environments, audit-trail-capable data export (CSV/TXT) supports 21 CFR Part 11 compliance when paired with validated third-party control software; pressure and flow logs include timestamped metadata, operator ID fields, and digital signature support.

Software & Data Management

The embedded firmware provides native serial communication (ASCII command set) for direct integration with LabVIEW, MATLAB, or Python-based automation frameworks. Optional Tongtian PumpControl Suite (v3.2+) offers graphical workflow scripting, multi-pump synchronization, and real-time overlay of pressure/flow trend curves against user-defined setpoints. All operational parameters—including cumulative volume dispensed, total runtime, and maximum observed pressure—are stored in non-volatile memory with automatic backup on power loss. Exported datasets include ISO 8601 timestamps, measurement uncertainty annotations per GUM (JCGM 100:2008), and traceable calibration certificate references.

Applications

• Preparative liquid chromatography: Stable gradient delivery in medium-pressure (5–10 MPa) flash and MPLC systems requiring ≤0.5% flow RSD over 8-hour runs
• Continuous-flow synthesis: Precise stoichiometric feeding into microstructured reactors (e.g., Corning AFR, Vapourtec E-Series) with thermal mass flow compensation
• Pharmaceutical formulation development: Controlled excipient addition during hot-melt extrusion or nanoprecipitation processes
• Environmental analysis: Automated leaching tests (EPA Method 1311) with programmable peristaltic bypass for solid-phase contact duration control
• Materials science: Sol-gel precursor injection for controlled mesoporous silica templating under inert atmosphere

FAQ

What certifications does the TBP1020S hold for use in GMP-regulated laboratories?
It carries CE marking for EMC and machinery safety; full 21 CFR Part 11 compliance requires deployment with validated third-party software and documented IQ/OQ/PQ protocols.
Can the pump handle abrasive slurries or particulate-laden fluids?
No—this model is designed exclusively for clean, particle-free liquids; suspended solids >5 µm will accelerate valve wear and invalidate warranty coverage.
Is remote firmware update supported via USB or network interface?
Firmware updates require physical connection via USB and Tongtian’s authorized FlashTool utility; no over-the-air (OTA) capability is implemented.
How is flow calibration traceability maintained?
Each unit ships with a NIST-traceable calibration certificate (ISO/IEC 17025 accredited lab); recalibration intervals are recommended every 12 months or after 2000 operating hours.
Does the pump support analog input for external flow setpoint modulation?
Yes—0–5 V DC and 4–20 mA analog inputs are available as optional hardware modules (order code: TBP1020S-AI).
