Jingrui 316L Stainless Steel High-Pressure Constant-Flow Pump

Overview

The Jingrui 316L Stainless Steel High-Pressure Constant-Flow Pump is an engineered solution for precise, stable, and corrosion-resistant fluid delivery in demanding laboratory and pilot-scale process environments. Designed around a positive displacement plunger architecture, it operates on the principle of reciprocating volumetric displacement with real-time electronic flow regulation—enabling consistent delivery across variable backpressures up to rated system limits. Constructed entirely from ASTM A240 316L stainless steel wetted parts, the pump delivers exceptional resistance to chloride-induced pitting, acidic/alkaline media, and high-temperature solvents commonly encountered in catalytic evaluation, electrochemical synthesis, and nuclear-related fluid handling. Its core architecture integrates a custom-profile cam mechanism, active electronic pulse suppression circuitry, and an integrated passive pulse damper—collectively reducing flow pulsation to <±0.5% RSD under steady-state conditions, meeting performance benchmarks required for microchannel reaction control and gradient-sensitive chromatographic applications.

Key Features

• 316L stainless steel fluid path—fully compliant with ASTM A240 and ASME BPE surface finish standards (Ra ≤ 0.4 µm electropolished options available)
• Digitally adjustable flow calibration—user-accessible offset correction via touchscreen interface to compensate for viscosity- or temperature-induced drift
• Multi-stage pulsation mitigation—mechanical cam optimization + real-time current feedback control + dual-chamber passive damper
• Integrated auto-cleaning function for plunger rod assembly (optional)—reduces seal wear and extends maintenance intervals by >40% under continuous operation
• 5-inch high-resolution capacitive touchscreen with ergonomic 15° tilt—designed for glove-compatible operation and reduced parallax error
• Remote start/stop capability via dry-contact I/O or Modbus RTU (RS-485)—compatible with PLC-based reactor control systems and SCADA integration
• Compact footprint (W × D × H: 220 × 360 × 280 mm)—enables vertical stacking of up to four units without thermal or vibration cross-talk
• Self-priming capability up to 5 m water column at ambient temperature—suitable for headspace-limited or elevated-position feed configurations

Sample Compatibility & Compliance

The pump is validated for use with organic solvents (e.g., DMF, THF, NMP), aqueous electrolytes (including LiPF₆ solutions), corrosive reagents (HCl, HNO₃, NaOH ≤ 30%), and high-viscosity polymer melts (up to 5,000 cP at 80°C). It conforms to CE machinery directive 2006/42/EC, RoHS 2011/65/EU, and carries IP54 ingress protection rating. For regulated environments, firmware supports audit-trail-enabled operation per FDA 21 CFR Part 11 when paired with compliant data acquisition software—supporting GLP/GMP documentation requirements in pharmaceutical process development and catalyst qualification studies.

Software & Data Management

The embedded control firmware provides real-time monitoring of flow rate, pressure, motor current, and temperature via the local HMI. Optional Ethernet/Wi-Fi module enables seamless integration with LabVIEW™, MATLAB® Data Acquisition Toolbox, or custom Python-based process orchestration platforms using standard TCP/IP socket protocols. All operational logs—including calibration events, fault codes, and manual flow adjustments—are timestamped and exportable as CSV or SQLite databases. Firmware updates are performed via signed binary packages to ensure integrity and traceability—critical for ISO 9001-certified QA/QC laboratories.

Applications

This pump serves as a primary feed module in heterogeneous catalysis testing rigs (e.g., fixed-bed and fluidized-bed reactors), microreactor arrays for photochemical and electrochemical synthesis, slurry delivery systems for battery electrode coating lines, and precision dosing in nuclear fuel cycle simulation experiments. It is routinely deployed in academic and industrial settings for controlled addition in precipitation reactions, polymerization kinetics studies, supercritical fluid processing, petrochemical cracking evaluation, and continuous-flow API manufacturing. Its compatibility with glass-lined, Hastelloy®, and sapphire-lined reactor interfaces ensures broad deployment across chemical engineering, materials science, and environmental process research domains.

FAQ

What is the maximum operating pressure specification?
Rated continuous pressure: 40 MPa (6,000 psi) at 25°C; derated linearly above 60°C per manufacturer’s thermal compensation curve.
Is the pump compatible with aggressive fluorinated solvents such as HFIP or TFEE?
Yes—316L construction combined with Kalrez® 7075 seals ensures stability in fluorinated media; full compatibility matrix available upon request.
Can flow rate be synchronized with external triggers (e.g., UV lamp pulses or potentiostat signals)?
Yes—TTL-compatible trigger input supports external event synchronization with sub-millisecond latency.
Does the auto-cleaning function require additional utility connections?
No—it utilizes internal solvent recirculation and programmable dwell cycles; no external wash-fluid supply needed.
Is validation documentation (IQ/OQ/PQ templates) provided for GMP environments?
Yes—comprehensive validation support package included with optional GxP compliance add-on license.
