Overview
The Deepflow CY3000401 Ultra Pure Water Circulation Pump is a precision-engineered recirculation module designed for integration into closed-loop ultra-pure water (UPW) distribution systems commonly deployed in semiconductor fabrication cleanrooms, pharmaceutical water-for-injection (WFI) loops, and high-sensitivity analytical laboratories. Unlike standard centrifugal pumps, the CY3000401 is constructed with electropolished 316L stainless steel wetted components and employs a brushless DC motor coupled to a hermetically sealed magnetic drive mechanism—eliminating mechanical seals and minimizing particle generation, leachables, and microbial harborage points. It operates on the principle of continuous, low-shear, laminar-flow recirculation to maintain TOC 18.2 MΩ·cm at 25 °C, and bacterial counts < 0.1 CFU/mL throughout the loop—critical performance benchmarks defined in ASTM D5127, ISO 3696 Class 1, and USP . The pump is not a standalone purification unit but a core circulation enabler within validated UPW systems where flow stability, pressure consistency, and material compatibility directly impact system-wide water quality integrity.
Key Features
- Electropolished 316L stainless steel fluid path with Ra ≤ 0.4 µm surface finish, compliant with ASME BPE-2022 surface roughness requirements for pharmaceutical-grade fluid systems
- Hermetic magnetic coupling drive—zero dynamic seals, eliminating seal degradation, lubricant contamination, and maintenance-induced particulate release
- Brushless DC motor with closed-loop speed control enabling precise flow rate regulation from 0.5 to 4.0 L/min ±1.5% full-scale repeatability
- Integrated pressure sensor (0–6 bar range) and temperature sensor (PT1000, –10 to 60 °C) with 4–20 mA analog outputs for PLC or SCADA integration
- IP65-rated enclosure with corrosion-resistant housing; CE-marked per EN 61000-6-2/6-4 and EN 60335-1 for laboratory and industrial environments
- Low-noise operation (<52 dB(A) at 1 m), optimized for placement within controlled laboratory utility corridors or equipment skids
Sample Compatibility & Compliance
The CY3000401 is validated for continuous duty with Type I ultrapure water as defined in ISO 3696 and ASTM D1193, including water meeting USP specifications for WFI and Purified Water. Its material composition—316L SS, FFKM (perfluoroelastomer) secondary gaskets, and PEEK isolation components—has been tested per USP for extractables and USP cytotoxicity screening. The pump supports compliance with FDA 21 CFR Part 11 when integrated with audit-trail-capable supervisory software, and its design facilitates qualification under GMP Annex 1 (2022) for sterile process water systems. It is not intended for use with organic solvents, acids, alkalis, or saline solutions outside pH 5.0–8.5.
Software & Data Management
The CY3000401 includes embedded firmware supporting Modbus RTU (RS-485) and optional Ethernet/IP communication protocols. When connected to a central monitoring platform—such as DeltaV, Siemens Desigo, or custom LabVIEW-based SCADA—the pump transmits real-time operational data including rotational speed, differential pressure, motor current draw, and thermal load. All parameter changes are timestamped and logged with user ID attribution, satisfying ALCOA+ data integrity principles. Firmware updates are performed via secure authenticated USB or network interface, with version rollback capability and SHA-256 checksum verification. Audit trails comply with GLP and GMP documentation requirements for traceability across calibration, maintenance, and operational events.
Applications
- Recirculation in point-of-use UPW loops serving ICP-MS, LC-MS/MS, and atomic absorption spectrometry systems requiring sub-part-per-trillion metal ion stability
- Continuous flow maintenance in pharmaceutical WFI distribution networks operating under first-use or constant-recirculation validation protocols
- Integration into modular ultrafiltration or UV-oxidation polishing skids where low-turbulence, non-cavitating flow prevents membrane fouling and photoreactor shadowing
- Backup or redundant circulation in Class 100 (ISO 5) cleanroom UPW supply lines where mean time between failure (MTBF) exceeds 25,000 hours
- Research-grade water delivery for nano-material synthesis labs where nanoparticle agglomeration must be avoided through shear-sensitive flow management
FAQ
Is the CY3000401 suitable for direct connection to reverse osmosis or EDI pretreatment units?
Yes—provided inlet water meets minimum feed specifications: conductivity < 10 µS/cm, silica < 0.1 mg/L, and free chlorine < 0.05 mg/L. A 0.2 µm prefilter is mandatory upstream.
Does the pump include built-in leak detection or dry-run protection?
It features electronic dry-run detection via motor current signature analysis and will shut down within 3 seconds of flow cessation; however, external liquid-level sensors or pressure-loss interlocks are required for full leak mitigation.
Can the CY3000401 be validated per IQ/OQ/PQ protocols?
Yes—Deepflow provides a URS-aligned validation support package including FAT/SAT documentation templates, calibration certificates for embedded sensors, and material traceability dossiers (EN 10204 3.1).
What is the recommended maintenance interval under continuous 24/7 operation?
Annual functional verification and surface passivation per ASTM A967 are advised; no scheduled bearing replacement is required due to the magnetically coupled design.
Is remote firmware update capability available without physical access?
Yes—when configured with optional Ethernet/IP connectivity and authorized network access, secure over-the-air updates can be initiated via TLS 1.2-encrypted API endpoints.
