KCB Series Gear Pump

Product Name: KCB Series Gear Pump

Product Overview:The KCB Series Gear Pump is a robust and versatile positive displacement pump, expertly designed for the efficient transfer of lubricating oils and liquids with similar physical properties. Renowned for its simple yet effective structure, this pump series is a staple in various industrial applications, including petroleum, chemical processing, metallurgy, mining, and food processing. It excels in handling media that are free of solid particles, fibers, and corrosive elements.

Key Features & Structural Advantages:

• Durable & Hardened Gears: The gears and shafts undergo advanced heat treatment, providing exceptional hardness and strength. This ensures superior wear resistance and an extended operational lifespan, even under continuous heavy-duty use.

• Built-in Overload Protection: The pump is equipped with a highly reliable safety valve. This valve automatically activates to protect the pump and pipeline system from overpressure caused by blockages or valve closures. The full reflux pressure is set at 1.5 times the rated discharge pressure and can be adjusted within allowable limits.

• Optimized Hydraulic Design: Featuring a scientifically designed oil泄 (drain) and return groove, the KCB series minimizes the torque force on the gears during operation. This results in reduced bearing loads, minimal wear, and significantly improved overall pump efficiency.

• Excellent Self-Priming Capability: With strong self-priming performance, the pump does not require pre-filling with liquid before startup, making it incredibly convenient and time-saving for daily operations.

• Automatic Lubrication: All internal components are automatically lubricated by the conveyed medium during operation, eliminating the need for an external lubrication system and simplifying maintenance.

• Flexible Material & Seal Options: While standard models are made of cast iron and carbon steel, stainless steel and copper gear variants are available. This allows the pump to handle slightly corrosive liquids, food-grade materials, or low flash-point liquids like gasoline. Various sealing options, including mechanical seals and packing seals, are offered to meet different temperature and leakage requirements.

Technical Specifications:

• Flow Rate: 1 - 60 m³/h (up to 580 m³/h for certain large-scale models)

• Working Pressure: ≤ 2.5 MPa

• Temperature Limit: Standard models are suitable for temperatures up to 80℃. High-temperature variants can handle media up to 300℃.

• Viscosity Range: 5 × 10⁻⁶ ～ 1.5 × 10⁻³ m²/s (5 - 1500 cSt). With reduced speed, it can handle viscosities up to 50,000 mm²/s.

• Rotation Direction: Clockwise (viewed from the prime mover end).

Typical Applications:

• Petroleum & Chemical Industry: Ideal for the transfer, pressurization, and circulation of crude oil, diesel, lubricating oils, and various chemical solvents.

• Mechanical Lubrication Systems: Widely used as a lubricating oil pump for large-scale industrial machinery and equipment.

• Fuel Supply Systems: Ensures a stable and efficient supply of fuel oil for burners, engines, and boilers.

• Food & General Processing: Stainless steel models are perfectly suited for transferring edible oils, beverages, and other non-corrosive food-grade liquids.
