KCB Series High Flow Gear Pump

Product Name: KCB Series High Flow Gear Pump

Product Overview:The KCB Series High Flow Gear Pump is a heavy-duty industrial fluid transfer solution engineered for large-scale operations. Designed as a high-capacity iteration of the classic KCB gear pump, it excels in moving substantial volumes of lubricating oils and liquids with similar properties. This pump series is an ideal choice for major infrastructure and industrial projects, including oil depots, ports, docks, shipyards, and large-scale pipeline transmission systems, where efficiency and reliability in high-volume fluid handling are paramount.

Key Features & Structural Advantages:

• Massive Flow Capacity: Specifically designed for large-volume applications, this series delivers exceptional flow rates ranging from 18 m³/h up to an impressive 112 m³/h (and even higher for customized large-scale models). It ensures rapid and efficient transfer of fluids in demanding environments.

• Robust Human-Shaped Gear Design: Unlike smaller models, the high-flow variants (typically KCB-300 and above) utilize a sophisticated set of four helical gears arranged in a human-shaped (herringbone) configuration. This advanced design ensures exceptionally smooth transmission, minimal flow pulsation, and extremely low operational noise and vibration.

• Differential Pressure Safety Valve: Equipped with a highly responsive differential pressure safety valve, the pump provides reliable overload protection. It automatically relieves excess pressure in the event of pipeline blockages or accidental valve closures, safeguarding both the pump and the entire piping system from damage.

• Heavy-Duty Construction: Built to withstand continuous heavy-duty use, the pump features a robust cast iron or steel body. The gears and shafts undergo rigorous heat treatment to achieve outstanding hardness and wear resistance, ensuring a prolonged operational lifespan even under high-load conditions.

• Optimized Hydraulic Efficiency: The internal structure includes scientifically engineered drain and return grooves that significantly minimize torque forces on the gears during rotation. This results in reduced bearing loads, lower friction, and maximized overall pump efficiency.

• Excellent Self-Priming Capability: The pump boasts strong self-priming performance, eliminating the need to pre-fill liquid before startup. This feature greatly simplifies daily operations and enhances overall workflow efficiency in large-scale transfer scenarios.

Technical Specifications:

• Flow Rate: 18 - 112 m³/h (300 - 1800 L/min)

• Working Pressure: 0.28 - 0.7 MPa (optimized for high-volume, low-to-medium pressure transfer)

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

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

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

• Sealing Options: Available with high-performance mechanical seals or packing seals to meet specific leakage and safety requirements.

Typical Applications:

• Port & Marine Logistics: Widely used in docks, harbors, and shipyards for the rapid loading, unloading, and transfer of crude oil, heavy oil, and diesel.

• Oil Depot & Pipeline Transmission: Serves as a primary booster or transfer pump in large oil depots and long-distance pipeline systems, ensuring stable and high-volume fluid movement.

• Large-Scale Industrial Lubrication: Provides a reliable and massive supply of lubricating oil for heavy machinery in metallurgy, mining, and power generation plants.

• Fuel Supply Systems: Ideal for the bulk transfer and pressurization of fuel oil in large industrial boilers, power stations, and marine engines.
