Technical Specifications

Operating Conditions

  • Liquid temperature range:
    • Standard version: −15°C to +70°C
    • Hot water version: +70°C to +110°C

  • Ambient temperature: ≤ +40°C

  • Maximum operating pressure: 10 bar

  • Maximum allowable inlet pressure: subject to system pressure limitations

  • Pumped liquids must be clean, non-flammable, of low viscosity, free from sulfides, solid particles, or fibers.

Service Conditions

  • Recommended for use in clean, ventilated indoor environments.

  • For outdoor installations, weatherproof covers and vibration-isolated foundations are advised.

  • Avoid direct sunlight and exposure to extreme temperature conditions.

  • Regular inspection of shaft seals, lubrication status, and wiring terminals is required for stable operation.

Protection Functions

  • Motor protection includes overload, phase failure, and over-temperature safeguards.

  • Check valves should be installed to prevent water hammer and backflow.

  • Pressure sensors at inlet and outlet can be integrated for system protection interlocks.

  • Dry running is strictly prohibited—use of level switches or dry-run protection modules is recommended.

Selection Criteria

  • Select pump model and impeller stages based on required flow rate and head.

  • Ensure material compatibility with pumped liquid considering pH, chloride content, temperature, etc.

  • Choose motor power with adequate safety margin based on actual working conditions.

  • Consider piping layout, connection orientation, noise level, and space availability.

  • For critical systems, dual-pump operation or duty/standby configuration is advised to enhance reliability.
