Tongtian TBP1010S Precision Constant-Flow Parallel-Flow Pump

Overview

The Tongtian TBP1010S is a high-precision constant-flow parallel-flow pump engineered for applications demanding continuous, pulse-free liquid delivery under stable pressure and flow conditions. Unlike conventional reciprocating piston pumps, the TBP1010S employs a parallel-flow architecture—where two ceramic plungers operate in precise phase opposition—to actively cancel volumetric displacement fluctuations. This design eliminates inherent pulsation typical of single- or dual-plunger systems, achieving pressure ripple ≤ 0.01 MPa across its full operating range (0–10.0 MPa) and flow range (0.1–10.0 mL/min). The pump operates on a microprocessor-controlled closed-loop feedback system that continuously monitors plunger position, motor torque, and real-time pressure to dynamically adjust actuation timing and velocity. It is not a peristaltic or diaphragm pump; rather, it is a positive-displacement, mechanically driven constant-flow instrument optimized for integration into automated fluid-handling workflows where reproducibility, chemical compatibility, and long-term stability are critical.

Key Features

• Parallel-flow dual-ceramic plunger mechanism with sapphire ball valves ensures ultra-low pulsation and extended service life in aggressive solvent environments.
• Selectively configurable wetted-path materials: 316L stainless steel (L), pure titanium (T), PEEK (K), or PTFE (F)—enabling compliance with ISO 10993 biocompatibility requirements and resistance to halogenated solvents, strong acids, and alkaline media.
• Integrated real-time pressure and flow monitoring with dual-channel digital display: shows setpoint vs. actual pressure (MPa) and flow rate (mL/min) simultaneously.
• Programmable timer function supports unattended operation with start/stop scheduling, duration-based shut-off, and automatic parameter retention upon power cycle.
• RS232/USB interface enables bidirectional communication with host PCs or PLCs for remote control, script-based sequencing, and audit-trail-capable data logging (compatible with FDA 21 CFR Part 11–compliant software platforms).
• Sealed drive train with IP54-rated enclosure minimizes maintenance and prevents ingress of particulates or vapors in laboratory or pilot-plant settings.

Sample Compatibility & Compliance

The TBP1010S accommodates a broad spectrum of Newtonian and mildly non-Newtonian liquids—including aqueous buffers, organic solvents (e.g., acetonitrile, THF, DCM), viscous reagents (up to 500 cP at 25°C), and corrosive feedstocks (e.g., HCl, HF, NaOH solutions). Its material options meet ASTM F2129 (corrosion resistance of metallic implants) and ISO 15195 (reference materials for calibration of viscometers) guidelines for inert fluid contact surfaces. When configured with titanium or PTFE-wetted paths, it satisfies USP extractables testing requirements for pharmaceutical process equipment. The pump’s pressure accuracy (≤ ±0.10 MPa) and flow repeatability (≤ ±0.5%) align with ISO 5725-2:2019 precision criteria for analytical instrumentation used in GLP/GMP-regulated environments.

Software & Data Management

The pump ships with Tongtian PumpControl v3.2—a Windows-based configuration utility supporting real-time graphical plotting of pressure vs. time and flow vs. time curves, multi-step gradient programming (flow ramping, pressure hold, timed pause), and CSV export of timestamped operational logs. All parameter changes—including flow setpoints, pressure limits, and timer configurations—are recorded with user ID, timestamp, and pre-/post-change values. Exported datasets include column headers compliant with MIAME and ISA-Tab metadata standards, facilitating integration into LIMS or ELN platforms. Firmware updates preserve historical calibration coefficients and retain user-defined presets across versions.

Applications

• Modular microreactor and tubular flow chemistry systems requiring stoichiometrically precise, pulse-free reagent introduction.
• Medium-pressure preparative chromatography (1–10 MPa), including flash purification, ion exchange, and size-exclusion setups with UV/ELSD detection.
• Corrosive feedstock delivery in catalyst screening rigs, electrochemical synthesis cells, and high-temperature/high-pressure autoclave feeding loops.
• Continuous dosing in bioprocess perfusion culture, enzymatic cascade reactors, and food-grade additive metering where sanitary validation is required.
• Calibration traceability for flow meters and pressure transducers per ISO/IEC 17025:2017 Annex A.2 guidelines.

FAQ

What distinguishes the TBP1010S from standard dual-plunger HPLC pumps?

It utilizes true parallel-flow kinematics—not staggered-phase reciprocation—resulting in near-zero net volumetric fluctuation and eliminating the need for active dampeners or passive accumulator chambers.
Can the pump be operated in pressure-control mode?

No. The TBP1010S is a constant-flow instrument with pressure-limit safety cutoff; it does not support closed-loop pressure regulation.
Is firmware upgrade supported in the field?

Yes. Updates are delivered via signed .hex files through the PumpControl software; all calibration constants remain intact post-upgrade.
Does the pump comply with electromagnetic compatibility directives?

Yes. Certified to IEC 61326-1:2013 Class A for industrial environments and EN 55011:2016 Group 1, Class B emission limits.
What maintenance intervals are recommended for continuous 24/7 operation?

Plunger seals and ball valves require inspection every 3,000 operating hours; full drive train lubrication is specified at 12,000 hours per Tongtian Maintenance Manual Rev. 4.2.
