Overview
The PreFluid SL360-XC45 is an industrial-grade, high-capacity peristaltic pump engineered for continuous, reliable transfer of demanding fluids in laboratory, pilot-scale, and process-critical environments. Based on the positive displacement principle of peristalsis—where rotating rollers compress elastomeric tubing to generate unidirectional flow—the SL360-XC45 delivers precise volumetric delivery without fluid contact with mechanical components. Its core architecture integrates a high-torque AC servo motor, a newly developed XC45 planetary gear reduction pump head, and a rigid stainless-steel chassis. This configuration enables stable operation at elevated backpressures (up to 3 bar typical with compatible tubing), extended tube life (2.5× longer than conventional roller heads due to optimized roller trajectory and reduced localized shear), and consistent performance across wide viscosity ranges—from water-like solvents to highly viscous catalyst slurries (up to ~10,000 mPa·s with appropriate tubing selection). Designed for uninterrupted operation in continuous-process settings—including distillation column feed, catalyst dosing, and chemical synthesis lines—the SL360-XC45 meets functional requirements aligned with ISO 8573-1 (compressed air quality) for cleanroom-adjacent use and supports traceable operation under GLP-compliant workflows when integrated with validated control systems.
Key Features
- AC servo motor drive with closed-loop speed and torque control—ensures stable output across variable load conditions and eliminates drift during extended runs
- XC45 planetary gear pump head featuring synchronized roller rotation and low-slip cam geometry—minimizes tube fatigue and extends service life up to 120 days under continuous high-flow operation
- High-resolution speed control (0.1 rpm increment) and calibrated flow estimation—achieving ±0.5% volumetric accuracy over full 10–360 rpm range
- Bilingual (English/Chinese) LCD interface with real-time display of speed, estimated flow rate, direction, run time, and system status
- 16 programmable parameter sets—enabling rapid recall of application-specific configurations for multi-step protocols
- Power-loss memory function—automatically resumes prior operational state (speed, direction, mode) after unexpected shutdown
- Multiple control options: front-panel keypad, external TTL-level start/stop trigger, pulse-width modulation input, and RS-485 Modbus RTU communication (addressable slave device)
- IP54-rated enclosure with corrosion-resistant coated housing—suitable for humid, chemically exposed lab and plant-floor environments
- Support for large-bore, reinforced tubing (inner diameters up to 16 mm)—facilitating high-volume transfer of abrasive or particulate-laden fluids
Sample Compatibility & Compliance
The SL360-XC45 accommodates a broad spectrum of elastomeric tubing materials—including platinum-cured silicone, fluoropolymer-lined silicone (e.g., Viton®-lined), EPDM, and Santoprene®—each selected based on chemical resistance, pressure rating, and temperature stability. Tubing selection directly governs maximum achievable pressure, flow linearity, and service interval; recommended tubing sizes (e.g., 12.7 mm ID) are validated per ASTM D1418 and ISO 8517 for peristaltic pump applications. While the pump itself does not require regulatory certification as a standalone device, its Modbus RTU interface supports integration into FDA 21 CFR Part 11–compliant data acquisition systems when paired with audit-trail-enabled SCADA or LIMS platforms. The unit complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for industrial environments and operates within ambient limits defined by ISO 14644-1 Class 8 cleanroom adjacent zones.
Software & Data Management
No proprietary PC software is bundled; however, the embedded Modbus RTU protocol (slave ID configurable, 9600–115200 bps) enables seamless integration with third-party automation platforms—including LabVIEW, MATLAB, Ignition SCADA, and DeltaV DCS—using standard Modbus function codes (03h, 06h, 10h). All operational parameters—including target speed, direction, run duration, and accumulated pulse count—are readable and writable via discrete registers. Timestamped event logging (start/stop, error codes, power cycle) is maintained in non-volatile memory and accessible via register polling. For GxP-aligned deployments, users may implement external validation protocols to verify command-response latency (<100 ms typical), data integrity (CRC-16 checksum enforced), and electronic signature support through upstream application logic.
Applications
- Continuous catalyst dosing into atmospheric and pressurized distillation columns (e.g., 15 m static head in petrochemical refining)
- Transfer of shear-sensitive biopolymers, cell suspensions, and fermentation broths in bioprocessing scale-up
- Accurate metering of aggressive reagents (e.g., concentrated acids, halogenated solvents) in fine chemical synthesis
- Recirculation of abrasive slurries containing catalyst particles or precipitates in heterogeneous catalysis reactors
- Primary fluid handling in environmental testing systems requiring long-duration, unattended operation
- Integration into automated sample preparation workstations for ICP-MS, HPLC, and titration systems where tubing isolation is mandatory
FAQ
What tubing sizes are supported by the XC45 pump head?
The XC45 head accepts tubing with inner diameters from 3.2 mm to 16.0 mm; recommended standard sizes include 6.4 mm, 9.5 mm, and 12.7 mm ID, depending on required flow rate and pressure tolerance.
Can the SL360-XC45 operate under vacuum or negative inlet pressure?
Yes—when properly primed and using appropriately rated tubing, it supports suction lifts up to 5 m water column (0.05 MPa vacuum) at ambient temperature.
Is the pump suitable for sterile or aseptic applications?
While the pump body is not autoclavable, single-use, gamma-sterilizable tubing kits (e.g., C-Flex® or Pharmed® BPT) can be deployed to meet ISO 13408-1 requirements for aseptic fluid path integrity.
How is flow calibration performed?
Calibration is conducted gravimetrically per ISO 8466-1: users measure dispensed mass over time using a certified balance, then adjust the internal flow coefficient via the LCD menu or Modbus register to correct for tubing compliance and viscoelastic effects.
Does the unit support analog speed control (e.g., 0–10 V or 4–20 mA)?
No—speed is digitally controlled only via keypad, RS-485, or digital triggers; analog input is not implemented in this model variant.
