SNF Three Screw Marine Oil Pump
**Project Description**
Our company produces the three-screw pump according to national standards GB10887-89, designed, manufactured, and tested. The three-screw pump is a type of rotary displacement pump that operates on the principle of screw meshing. As the screws rotate within the pump housing, they create sealed cavities that move the fluid along the axial direction of the screws, delivering it continuously and uniformly, thus providing stable system pressure.
This pump is suitable for conveying non-corrosive oils and similar lubricating liquids. It can handle a wide range of viscosities, from 3.0 to 760 mm²/s (1.2 to 100 °E), with high-viscosity media requiring heating before delivery. The operating temperature generally does not exceed 350°C.
**Applications**
The three-screw pump is mainly used for transporting high-viscosity and high-temperature lubricating liquids. It is commonly applied in the transfer of asphalt, heavy fuel oil, gear oil, and other similar fluids. The heat carrier can be steam, hot oil, or hot water, while cold carriers can be gas or liquid. This product is widely used across industries such as petroleum, chemical, metallurgy, machinery, electrical, and more.
**Advantages**
1. Wide range of pressure and flow: Flow range from 0.2 to 600 m³/h, with maximum working pressure up to 6.3 MPa.
2. Suitable for various types of liquids and viscosity ranges.
3. Low rotational inertia, allowing for high-speed operation.
4. Excellent suction capability and self-priming ability.
5. Smooth and continuous flow, minimal vibration, and low noise.
6. Less sensitive to gas and impurities entering the pump.
7. Robust structure, easy installation and maintenance.
8. Self-priming capability.
9. Flexible installation options: horizontal, flange, or vertical.
10. Customizable structures for heating or cooling mediums based on requirements.
