Characteristic:

IR heat preservation pump's main flow part has hollow interlayer, and multi-cycle for transporting the steam, hot water, hot oil and soda pop. Heat preservation has a variety of ways with the heat preservation outside. 

Core Technologies:

1. Advanced Thermal Management System

• Triple-Layer Jacketing:

  • Inner heat transfer layer (316L stainless steel)

  • Middle insulation layer (ceramic fiber)

  • Outer protective cladding (304 stainless steel)

• Steam/Oil Circulation Channels:

  • Standard steam heating (150-220°C)

  • Optional thermal oil system (up to 450°C)

  • Electric trace heating options available

2. High-Temperature Mechanical Design

• Hot-Oxidation Resistant Materials:

  • Shaft: Incoloy 800H (standard), Hastelloy X (optional)

  • Bearings: High-temperature graphite lubricated

  • Seals: Gas-lubricated dry-running or double cartridge seals

• Thermal Expansion Compensation:

  • Floating bearing design accommodates 15mm axial expansion

  • Flexible coupling with ±5° angular misalignment capacity

3. Smart Temperature Control

• Integrated Sensors:

  • RTD temperature monitoring (4-20mA output)

  • Vibration analysis for bearing health

  • Heat medium flow control valves

• Automation Interface:

  • MODBUS RTU/Profibus DP protocols

  • Predictive maintenance alerts
