Irian 2PE High-Flow / Large-Capacity Dual-Piston Pump

Overview

The Irian 2PE High-Flow / Large-Capacity Dual-Piston Pump is an engineered precision fluid delivery system designed for laboratory-scale and pilot-plant applications requiring stable, repeatable volumetric flow across an exceptionally wide dynamic range—from trace-level micro-injection to high-throughput continuous displacement. Its dual-cylinder architecture employs two independently actuated pistons (P1 and P2) housed within a thermally stabilized double-walled chamber, enabling precise thermal management of both working fluid and cylinder walls via external heat-transfer fluid circulation. The system operates on the principle of positive displacement with real-time pressure and temperature feedback, ensuring compliance with fundamental metrological requirements for controlled fluid dynamics experiments. It is not intended for corrosive or abrasive media, and its mechanical design adheres to EN 60204-1 (electrical safety) and PED 2014/68/EU (Pressure Equipment Directive) for equipment operating up to 25 bar.

Key Features

• Dual-piston configuration: P1 (low-flow, 0.013–100 L/h, 3 L capacity) and P2 (high-flow, 100–6,000 L/h, 30 L capacity) enable seamless transition between precision metering and bulk transfer without hardware reconfiguration.
• Thermally isolated double-wall cylinder housing, compatible with external heating/cooling circulators for active temperature control between +20 °C and +50 °C.
• Integrated metrology suite: one high-resolution pressure transducer (50 bar FS, 0.01 bar resolution), three calibrated PT100 sensors (two embedded at cylinder end caps, one at motor-proximal outlet), and internal strain-gauge instrumentation for in-situ thermal expansion compensation during pressure calibration.
• Real-time process monitoring via two isolated 4–20 mA analog outputs (configurable for pressure, temperature, or flow-derived signals) and encoder-based motor speed feedback for closed-loop rotational control.
• Fail-safe pressure management: programmable electronic pressure threshold triggers immediate motor de-energization; certified explosion-proof components meet ATEX Category 2G (Zone 1) requirements.
• Industrial-grade control interface compliant with fluidmodBus RTU protocol for integration into SCADA, DCS, or PLC-based automation environments.

Sample Compatibility & Compliance

The 2PE pump is constructed entirely from ASTM A240 UNS S31603 (316L stainless steel), offering high resistance to pitting and crevice corrosion in aqueous and mildly organic environments. It is validated for use with non-corrosive, non-abrasive, low-viscosity fluids—including water, glycol/water mixtures, hydrocarbon solvents (e.g., hexane, toluene), and silicone oils—provided vapor pressure remains below 10 kPa at operating temperature. Fluid compatibility must be verified per ISO 15142-1 for elastomer seals (standard FKM O-rings). The system complies with EU Machinery Directive 2006/42/EC, Electromagnetic Compatibility Directive 2014/30/EU, and carries CE marking. Calibration documentation includes traceable NIST-equivalent reference standards and uncertainty budgets aligned with ISO/IEC 17025:2017 requirements.

Software & Data Management

While the 2PE operates as a standalone hardware platform, its fluidmodBus RTU interface supports bidirectional communication with third-party supervisory software (e.g., LabVIEW, MATLAB, or custom Python-based control suites using Modbus RTU libraries). All sensor readings—including pressure, differential temperature across the cylinder, outlet temperature, and motor RPM—are timestamped and accessible in real time. The system logs operational events (e.g., pressure limit breach, thermal deviation, emergency stop) with millisecond-resolution timestamps. For regulated environments, optional firmware extensions support audit-trail functionality compliant with FDA 21 CFR Part 11, including user authentication, electronic signatures, and immutable event logging—enabling deployment in GLP or GMP-aligned method development workflows.

Applications

• Calibration and validation of inline flow meters (Coriolis, ultrasonic, turbine) under variable pressure and temperature conditions.
• Dynamic pressure testing of filtration membranes, heat exchangers, and microfluidic devices across multi-decade flow ranges.
• Feedstock delivery in continuous-flow chemical synthesis rigs where stoichiometric accuracy and thermal stability are critical.
• Long-duration durability testing of hydraulic actuators, valves, and seal assemblies under cyclic load profiles.
• Reference-grade fluid dispensing for inter-laboratory round-robin studies requiring sub-0.5% volumetric repeatability over 8-hour continuous operation.

FAQ

What fluids are incompatible with the 2PE pump?
Fluids with pH 10, halogenated solvents (e.g., chloroform, carbon tetrachloride), strong oxidizers (e.g., nitric acid, hydrogen peroxide >30%), or slurries containing particles >5 µm are strictly prohibited.
Is on-site installation support available?
Yes—qualified field service engineers provide commissioning, mechanical alignment verification, sensor calibration cross-check, and operator training per Irian’s Standard Commissioning Protocol (SCP-2PE Rev. 3.1).
Can the system operate unattended for extended periods?
It is rated for continuous duty (IEC 60034-1 S1 rating) and includes redundant thermal and pressure interlocks; however, unattended operation beyond 12 hours requires prior risk assessment per ISO 12100 and documented mitigation of fluid degradation or seal fatigue risks.
Does the calibration certificate satisfy ISO/IEC 17025 requirements?
The base certificate is issued by Irian’s ISO/IEC 17025-accredited metrology lab (accreditation No. COFRAC 1-1234); full uncertainty budgets and traceability chains are provided upon request.
What maintenance intervals are recommended?
Piston seal replacement every 2,000 operating hours or annually (whichever occurs first); lubrication of linear guides every 500 hours; full system verification (pressure/temperature linearity, flow repeatability) every 6 months or after any major component replacement.
