Sanotac SHP0010 High-Pressure Constant Flow Pump with PROFIBUS and PROFINET Communication

Overview

The Sanotac SHP0010 is a high-pressure constant flow pump engineered for precision fluid delivery in demanding laboratory and industrial process automation environments. Designed around positive displacement plunger technology, it delivers stable, pulse-minimized flow under sustained high backpressure—up to 42 MPa (6,090 psi)—making it suitable for applications including high-performance liquid chromatography (HPLC) pre-injection systems, catalytic reaction loop control, microreactor feed, and high-pressure synthesis setups. Unlike conventional serial bus pumps constrained by low-bandwidth protocols, the SHP0010 integrates native industrial fieldbus support—PROFIBUS DP V0 and PROFINET RT—enabling deterministic, sub-millisecond cycle times in multi-pump networks. Its dual-port PROFINET interface functions as an embedded two-port switch, eliminating external topology limitations and supporting line, star, or ring topologies per IEC 61158 and IEC 61784-1 standards. The pump operates on closed-loop speed and pressure feedback, with real-time monitoring of both pressure and flow trajectories via onboard digital signal processing.

Key Features

• Industrial-grade communication: Full PROFIBUS DP V0 implementation (GSD file included) with auto-baud detection up to 1.5 Mbps; PROFINET RT compliant (GSDML file provided), certified for seamless integration with Siemens SIMATIC S7-1200 PLCs—including complete configuration examples and device diagnostics.
• High-fidelity flow control: Dual-drive parallel plunger head architecture with solvent compressibility compensation and multi-point volumetric calibration curves, achieving ≤ ±0.5% repeatability (per AP-series specification baseline).
• Intelligent pressure management: Programmable upper/lower pressure limits with automatic shutdown and alarm logging; real-time pressure curve visualization via local display or remote HMI interface.
• Low-pulse operation: Cam-profile motion compensation combined with electronic flow pulsation suppression reduces pressure ripple to < 0.5% RMS across full operating range.
• Flexible unit handling: Switchable flow units between mL/min (volumetric) and g/min (mass-based), with user-configurable density input for gravimetric dosing.
• Maintenance-aware design: Integrated plunger rod rear-wash function prevents crystalline deposit accumulation at seal interfaces—critical for salt-containing mobile phases or reactive reagents.
• Modular wetted path options: Standard 316L stainless steel; optional Hastelloy C-276 or PTFE-lined fluidic paths for aggressive chemistries (e.g., halogenated solvents, strong acids/bases).

Sample Compatibility & Compliance

The SHP0010 supports continuous delivery of low-to-medium viscosity Newtonian and mildly shear-thinning fluids (e.g., aqueous buffers, organic solvents, polymer solutions up to ~500 cP). It is not intended for abrasive slurries, particulate-laden streams, or non-lubricating gases. Wetted material selection aligns with ASTM F2136 (elastomer compatibility) and ISO 10993-5 (cytotoxicity screening for pharmaceutical use cases). Firmware and communication stacks comply with IEC 61508 SIL 2 functional safety prerequisites for pump enable/disable signaling. Audit trail functionality—including parameter change logs, pressure/flow event timestamps, and firmware version history—supports GLP/GMP documentation requirements per FDA 21 CFR Part 11 when deployed with validated SCADA or LIMS platforms.

Software & Data Management

The pump includes embedded web server access (HTTP/HTTPS) for configuration and real-time telemetry without proprietary software. All fieldbus parameters are accessible via standard OPC UA nodes (compliant with Companion Specification for Pumps, OPC UA Part 122). Local display provides synchronized dual-curve plotting (pressure vs. time, flow vs. time) with zoom, hold, and export-to-CSV capability. Configuration backups and firmware updates are performed via secure TFTP or USB mass storage mode. Device diagnostics—including motor current draw, temperature gradient across heat sinks, and plunger position error—feed into predictive maintenance algorithms when connected to cloud-edge analytics platforms (e.g., MindSphere, ThingWorx).

Applications

• HPLC and UHPLC auxiliary pumping: Solvent blending, gradient delay line pressurization, column oven backpressure regulation.
• Continuous-flow chemistry: Precise stoichiometric reagent feeding into microstructured reactors or tubular catalytic beds.
• Nuclear fuel cycle R&D: High-purity nitric acid or TBP/kerosene solution delivery under shielded glovebox conditions.
• Petrochemical process simulation: High-pressure hydrocarbon injection in PVT cell studies and enhanced oil recovery modeling.
• Pharmaceutical continuous manufacturing: API crystallization feed control, dissolution media delivery in automated USP apparatus II systems.
• Environmental testing: Certified reference material (CRM) spiking into online ICP-MS or IC systems with trace-level accuracy.

FAQ

Does the SHP0010 support EtherNet/IP or CANopen?
No. Native protocol support is limited to PROFIBUS DP V0 and PROFINET RT. Third-party protocol gateways may be used, but are not validated or supported by Sanotac.
Can the pump operate continuously at 42 MPa?
Yes, provided ambient temperature remains within 10–40 °C and fluid viscosity stays above 0.3 cP. Continuous operation at maximum pressure requires use of the stainless steel or Hastelloy variant and adherence to scheduled seal replacement intervals (every 1,000 hours at >35 MPa).
Is flow calibration traceable to NIST standards?
Calibration is performed using gravimetric methods per ISO 4064-2. While Sanotac does not issue NIST-traceable certificates by default, accredited third-party calibration services (e.g., A2LA-accredited labs) can perform on-site verification with documented uncertainty budgets.
What is the minimum programmable flow rate increment?
0.001 mL/min for models with 0.001–9.999 mL/min range (e.g., AP0010); 0.01 mL/min for higher-flow variants such as SP0530 and above.
How is firmware updated in a PROFINET network?
Via PROFINET DCP (Discovery and Basic Configuration Protocol) using engineering tools like Siemens TIA Portal. Updates are delivered as signed .pnio files and require write-access authorization level 3.
