Sanotac VP0506 High-Viscosity High-Pressure Constant Flow Piston Pump

Overview

The Sanotac VP0506 is a high-precision, high-pressure constant flow piston pump engineered for reliable delivery of highly viscous fluids in demanding laboratory and pilot-scale process environments. Based on dual-piston parallel architecture with cam-driven actuation and floating plunger design, the pump operates on positive displacement principles to ensure volumetric accuracy independent of fluid rheology—critical when handling non-Newtonian or shear-thinning media such as silicone oils, glycerol, photoresists, polymer melts, and catalyst slurries. Its capability to maintain stable flow up to 1000 cP (at reduced flow rates) distinguishes it from conventional HPLC or syringe pumps, which typically fail above 50–100 cP due to mechanical limitation and excessive backpressure-induced slip. The VP0506 integrates real-time pressure and flow monitoring, electronic pulse suppression, and cam-profile compensation to achieve low-pressure pulsation (<0.05 MPa) and high repeatability (≤0.1%), making it suitable for applications requiring strict mass balance control, closed-loop gravimetric feeding, or integration into automated reaction systems.

Key Features

• Dual parallel piston configuration with floating plunger design ensures consistent volumetric displacement across wide viscosity ranges (0–1000 cP)
• Cam-driven actuation with precision-machined cam profile, combined with real-time electronic flow pulse suppression, reduces pressure ripple to ≤0.05 MPa
• Configurable flow units: volumetric (mL/min) and gravimetric (g/min) modes, supporting density-based mass flow conversion
• User-accessible flow calibration interface enabling multi-point correction across 0.01–100.00 mL/min range for system-specific compensation
• Programmable operation modes: constant-flow and gradient-flow profiles with programmable ramp rates and dwell times
• Integrated pressure and flow curve visualization via front-panel display and SanoFlu software; real-time trend logging to Excel-compatible CSV files
• Comprehensive safety logic: user-definable upper/lower pressure limits with automatic shutdown and fault logging
• Industrial-grade communication suite: RS-232, RS-485/422 (optional), Modbus RTU and ASCII protocols for seamless PLC integration and SCADA compatibility
• Scalable control architecture: supports 1:N master-slave configuration (up to 32 units), enabling synchronized multi-pump gradient systems
• Gravimetric closed-loop option: compatible with external analytical balances (0–5 V or 4–20 mA input) for dynamic feed rate adjustment based on real-time weight loss

Sample Compatibility & Compliance

The VP0506 accommodates chemically aggressive and thermally sensitive fluids through its wetted path constructed from 316L stainless steel, PTFE seals, sapphire check valves, and ceramic plungers—providing resistance to corrosion, abrasion, and thermal degradation. It complies with general-purpose electrical safety standards (IEC 61010-1) and electromagnetic compatibility (EMC) requirements per EN 61326-1. While not certified for explosion-proof (ATEX/IECEx) or pharmaceutical-grade (USP , FDA 21 CFR Part 11) use out-of-the-box, its audit-ready data logging (timestamped pressure/flow curves, parameter change history, and session metadata) supports GLP/GMP-aligned workflows when deployed with validated SOPs and electronic signature protocols. All firmware and SanoFlu software updates are version-controlled and traceable, facilitating regulatory documentation during equipment qualification (IQ/OQ/PQ).

Software & Data Management

The SanoFlu Fluid Control Management System provides native Windows-based configuration, real-time monitoring, and post-run analysis. It records timestamped pressure and flow trajectories at configurable sampling intervals (10 ms–1 s), stores settings—including serial port parameters, pressure thresholds, and gradient programs—and exports raw data to CSV for third-party statistical analysis (e.g., JMP, MATLAB, Python pandas). Audit trail functionality logs operator ID (via optional Windows login integration), parameter modifications, start/stop events, and error codes. Remote operation is supported via TCP/IP over RS-232-to-Ethernet converters, enabling centralized control in multi-reactor installations. Data export conforms to ISO/IEC 17025 traceability requirements when paired with calibrated reference standards.

Applications

• Microreactor feed systems requiring precise stoichiometric delivery of viscous reagents (e.g., epoxy resins, polyurethane prepolymers)
• Catalytic evaluation rigs: continuous dosing of metal-organic catalyst slurries into fixed-bed or slurry-phase reactors
• Supercritical fluid processing: CO₂-soluble polymer solutions and dense-phase solvent delivery under elevated backpressure
• Plastics modification: metered injection of plasticizers, fillers, or compatibilizers into twin-screw extruders or melt mixers
• Advanced materials synthesis: controlled dispensing of photoresists, battery electrode slurries, and ceramic pastes in R&D coating lines
• Chemical foam extrusion: simultaneous multi-stream feeding of polymer melt and blowing agent for cell structure optimization
• Electrochemical flow cells: stable electrolyte circulation under high-viscosity ionic liquid conditions
• Energy research platforms: fuel precursor injection in pyrolysis or hydrothermal liquefaction test benches

FAQ

What is the maximum viscosity the VP0506 can handle at full rated flow?
At 50 mL/min, the pump is rated for viscosities up to 100 cP; however, with flow reduction (e.g., ≤5 mL/min), it maintains stable delivery up to 1000 cP—verified using calibrated silicone oil standards per ASTM D2196.
Does the pump support FDA 21 CFR Part 11 compliance?
Out-of-the-box, the VP0506 does not include electronic signature or audit trail features required for Part 11 compliance; however, its SanoFlu software architecture supports integration with validated third-party e-signature modules and time-stamped log archiving when deployed in qualified environments.
Can I integrate this pump with my existing PLC system?
Yes—the VP0506 supports Modbus RTU over RS-485 and analog I/O (0–5 V, 4–20 mA), enabling direct integration with Allen-Bradley, Siemens, and Omron PLCs without intermediate gateways.
Is flow calibration traceable to national standards?
Calibration is performed using gravimetric methods with NIST-traceable analytical balances and certified volumetric glassware; users may document their own calibration procedures against ISO/IEC 17025-accredited reference standards.
What maintenance intervals are recommended for continuous operation?
Under typical lab conditions (8 h/day, 5 days/week), seal replacement is recommended every 6 months; cam and plunger inspection every 12 months; full pump head service every 24 months—detailed in the English-language maintenance manual supplied with each unit.
