LYB Series Vertical Gear Pump

Product Name: LYB Series Vertical Gear Pump

Product Overview:The LYB Series Vertical Gear Pump is a robust and highly efficient positive displacement pump specifically engineered for vertical installation. Renowned for its space-saving design and exceptional self-priming capabilities, this series is widely utilized in marine, petroleum, and heavy industrial applications. It excels at transferring lubricating oils, fuel oils, and other non-corrosive liquids free of solid particles and fibers. Its vertical configuration makes it the perfect solution for deep-tank suction and applications where floor space is limited.

Key Features & Structural Advantages:

• Space-Saving Vertical Design: The vertically oriented structure significantly reduces the footprint of the equipment, making it ideal for installation in confined spaces such as ship engine rooms, oil depots, and compact industrial setups.

• Exceptional Self-Priming & Suction Capability: The LYB series is designed to handle challenging suction conditions. Its vertical configuration allows for direct insertion into oil pools or tanks, effectively solving the common issue of suction difficulties encountered with horizontal pumps in deep oil levels.

• Advanced Gear Profile: Featuring a double-arc sine curve gear tooth profile, the pump ensures smooth meshing without relative sliding between tooth surfaces. This advanced design minimizes wear, eliminates liquid trapping, reduces operational noise, and significantly extends the service life of the gears.

• Reliable & Durable Operation: Built for continuous heavy-duty use, the LYB pump operates with remarkable stability, low vibration, and high efficiency. It is equipped with high-performance mechanical seals as standard, with packing seals available as an option to meet specific leakage prevention requirements.

• Built-in Overload Protection: The pump comes standard with a reliable safety valve. This valve automatically activates to relieve excess pressure in the event of pipeline blockages or accidental valve closures, safeguarding both the pump and the entire piping system from damage.

• Versatile Installation Options: The pump's design allows for flexible installation, including direct insertion into tanks or mounting on tank tops. For deeper applications, the pump shaft and structure can be extended to meet specific depth requirements.

Technical Specifications:

• Flow Rate: 8 - 300 m³/h (depending on the specific model)

• Working Pressure: Up to 0.6 MPa (standard models, customizable for higher pressures)

• Temperature Limit: Suitable for media temperatures up to 80℃ (standard); high-temperature variants can handle media up to 200℃

• Viscosity Range: 5 - 1500 cSt (mm²/s)

• Material Options: Cast Iron, Carbon Steel, and Stainless Steel (upon request)

• Sealing Options: High-performance mechanical seals (standard) or packing seals (optional)

Typical Applications:

• Marine & Shipbuilding Industry: Widely used as a lubricating oil transfer pump, fuel oil supply pump, and bilge pump on various types of vessels, ensuring reliable fluid handling in marine environments.

• Petroleum & Chemical Industry: Ideal for the transfer, pressurization, and circulation of crude oil, diesel, heavy oil, and various chemical solvents in depots, refineries, and pipeline systems.

• Industrial Lubrication Systems: Serves as a dependable lubricating oil pump for large-scale compressors, (refrigeration units), and heavy machinery in metallurgy, mining, and power generation plants.

• General Fluid Transfer: Perfect for handling various lubricating and non-lubricating oils in general industrial settings where vertical installation and strong suction capabilities are required.
