KCB Series Marine Gear Oil Pump

KCB Series Marine Gear Oil Pump | Heavy-Duty Lubrication & High-Viscosity Fluid Transfer Solutions

Product Overview
The KCB Series Marine Gear Oil Pump delivers superior performance in handling high-temperature, high-viscosity fluids across demanding marine and industrial applications. Engineered as an advanced upgrade to 2CY pump models, these robust gear pumps feature integrated safety reflux valves and handle temperatures up to 300°C. With exceptional viscosity capabilities from 5-1,500 cSt (extendable to 50,000 cSt at reduced speeds), KCB pumps efficiently transfer non-corrosive lubricating oils and similar fluids without solid particles or fibrous content.
