1. The screw pump delivers various media smoothly without pulsation. It ensures a continuous flow by using the medium itself as a sealing liquid within the casing. This design allows for excellent self-priming capability and the ability to handle liquids mixed with gas or air. 2. With an exceptionally low NPSHr, this pump offers superior suction performance thanks to its unique internal structure. 3. Equipped with external bearings that are individually lubricated, it can handle non-lubricating fluids effectively. 4. The use of synchronous gears eliminates direct metal-to-metal contact between rotating parts, making it safe even under dry running conditions for short periods. 5. Available in multiple configurations such as horizontal, vertical, or with a liner, the pump is suitable for a wide range of applications including clean liquids, low and high viscosity fluids, and even some corrosive media when the right material is selected. 1. Handling various liquids without solid particles. 2. Viscosity range: 1–1500 mm²/s; can go up to 3×10ⶠmm²/s at reduced speed. 3. Pressure range: Up to 4.0 MPa. 4. Capacity range: 1–2000 m³/h. 5. Temperature range: -15°C to 280°C. 1. Shipbuilding: Used for cargo and stripping pumps, ballast pumps, lubricating oil pumps, fuel oil transfer, spray pumps, and loading/unloading oil pumps. 2. Power Plants: Heavy and crude oil transfer pumps, heavy oil burning pumps. Chemical industry: Transfer of acids, alkalis, resins, dyes, printing inks, paints, glycerin, and paraffin wax. 3. Oil Refinery: Transfer of heating oil, asphalt oil, tar, emulsions, and asphalt. Also used for loading/unloading oil goods on tankers and in oil storage facilities. 4. Food Industry: Used in breweries, food processing plants, sugar refineries, tin factories, etc., for transferring alcohol, honey, sugar juice, toothpaste, milk cream, soy sauce, vegetable oil, animal oil, and wine. 5. Oil Fields: For transferring various types of oil and crude oil.

Production Overview
The Qing Sword typically has a slightly curved blade with a length ranging from around 70 to 100 centimeters. The blade is made of high-quality steel and is known for its sharpness and durability. The hilt, or handle, of the sword is usually made of wood or bone and is often adorned with decorative elements such as carvings or metal fittings.
One distinctive feature of the Qing Sword is its guard, which is typically in the shape of a circular or oval ring. This guard not only protects the hand of the wielder but also provides balance and stability to the sword during combat. The pommel, or end of the hilt, is often shaped like a horse's hoof, representing the military association of the Qing Dynasty
