Section 3: Advantages and Features:
1. High efficiency → Low operational costs
2. Modular design of universal interchangeable pump core components and parts (MF/MG) → Easy for maintenance and repair
3. Screw shaft rotor axial force balance (patented technology for high-pressure driven screw shaft oil balance) → Main shaft bearing does not bear axial force; driven rod hydraulic balance
4. Single shaft seal → Easy maintenance, low cost
5. Broad applicability of magnetic drive, sealless, and leak-proof design version
6. Availability of semi-submersible suspended and long-arm designs → Customized diving depths, addressing the requirement for pump self-priming capability exceeding atmospheric pressure.
7. Patented 5-axis sleeve positioning support design, strong resistance to cavitation and gas explosion → Low noise, minimal vibration
8. Multiple bearing lubrication solutions → Enables conveyance of low viscosity or high-temperature media
9. Misalignment design for import/export → Ensures smoother flow within the pump cavity
10. Wide applicability of the magnetic drive, sealless, and leak-proof design version
11. Availability of semi-submersible suspended and long-arm designs → Customizable diving depths, addressing operational conditions where the pump's self-priming capability exceeds atmospheric pressure.
12. Jacketed Insulation Design → Solves the Problem of High-Temperature Transmission Medium
13. Various oil inlet and outlet arrangements → Satisfy diverse on-site installation conditions
14. Diverse installation methods available: horizontal, vertical, flanged, and suspended options
