III. Advantages and Features:

1. High Efficiency → Low Operating Costs

2. Modular design of general interchangeable pump core components and parts (MF/MG) - Easy for maintenance and repair

3. Axial force balance of screw rotor (patented technology of high-pressure oil balance for driven screw) → Main shaft bearing does not bear axial force; hydraulic balance of the driven shaft

4. Single shaft seal → Easy maintenance, low cost

5. Wide applicability of magnetic drive versions with a sealless and leak-proof design

6. Availability of semi-submersible suspended and long-arm designs → Customized diving depth, addressing the operational conditions where the pump's self-priming capability exceeds atmospheric pressure.

7. Patented 5-axis sleeve positioning support design, strong resistance to cavitation and gas bursting → low noise, minimal vibration

8. Multiple bearing lubrication solutions → Enables the conveyance of low-viscosity or high-temperature media

9. Misalignment design for import and export → Ensures smoother flow within the pump cavity

10. Wide applicability of magnetic drive, sealless, and leak-proof design version

11. Availability of semi-submersible suspended, long arm design → Customizable diving depth, addresses the need for pump self-priming capability exceeding atmospheric pressure.

12. Jacketed Insulation Design → Solves the Problem of High-Temperature Conveying Medium

13. Various oil inlet and outlet arrangements → Meet various on-site installation conditions

14. Diverse installation options available → Horizontal, vertical, flanged, and suspended multiple solutions

4. Product Applications and Functions:

The SMH series triple screw pumps are commonly used in power plants for ignition fuel supply pumps, sealing oil pumps, control oil pumps, ignition fuel supply pumps, boiler burner boost injection pumps, and aromatic oil pumps and boost oil pumps in tire rubber and plastic factories. For example:

1. Diesel heavy oil fuel oil pumps for supply, conveyance, replenishment, feeding, pressurization, combustion, atomization, and ignition pumps.

2. Used in the machinery industry for conveying hydraulic oil and lubricating oil pumps, as well as gear oil hydraulic pumps, lubricating oil pumps, circulating oil pumps, cooling oil pumps, sealing oil pumps, booster oil pumps, and remote-controlled hydraulic motors; hydraulic testing, bearing gear shaft bushes for medium to large-sized gearboxes, pipeline flushing oil pumps, hydraulic cylinder drives, stage lifting.

3. For conveying and backflow, loading and unloading, oil extraction, shipment, supply, liquid pumps, and high-flow long-distance original collection and transportation boosting in the petrochemical industry.

4. Used on vessels for supply, barge, cleaning, cargo handling, fuel oil, measurement, anchor mechanism braking control, steering gear drive pump, and other hydraulic system pumps; also serves as fuel supply pumps and combustion spray pumps for ship boiler low sulfur fuel oil.

5. And virtually all industrial oil product pumping applications.
