KCB Gear Pump for Fuel Transfer in the CIS Region
KCB-300 gear pumps were supplied for diesel and heavy fuel oil transfer at a logistics depot. The reported duty was 18 m³/h per pump.
Project Approach
This project is documented from the reported operating data below. For a comparable duty the required flow, purity or head, pressure, temperature, medium properties and operating schedule are confirmed first, then the equipment family and configuration are selected against those values.
Reported Scope and Duty
Reported for this installation: application — Fuel transfer, model — KCB-300, medium — Diesel / heavy fuel oil. These are the figures reported for this project and are not a guarantee for other sites.

How a Similar Project Is Specified
Send the application and the required capacity first. The configuration is then fixed against the duty point, the operating environment (indoor or outdoor, ambient temperature, power supply) and the applicable site or regional requirements. Where a purity, pressure or flow is not yet fixed, the achievable range is confirmed before equipment is proposed.
Frequently Asked Questions
Why must lubricating oil fed to a KCB gear pump be clean and dry?
In an external gear pump the pumped oil seals the clearances between gears and casing and lubricates the close-running parts. Abrasive solids erode those surfaces and raise internal slip, while water breaks down the oil film and promotes corrosion — so filtration and water separation protect pump performance.
Does a KCB gear pump deliver constant flow on a lube-oil circuit?
As a positive-displacement pump it moves a nearly fixed volume per revolution, so flow is set mainly by speed, not by discharge pressure. Internal slip rises slightly at higher pressure or lower viscosity, and an integral relief valve set below the maximum allowable pressure protects the pump and circuit.
What is the difference between a gear pump and a screw pump for lubricating oil?
An external gear pump is compact, economical and standard for lube-oil transfer and circulation at moderate pressure. A triple-screw pump gives smoother, lower-pulsation flow for large or high-temperature oil duties — Qingdao Green Power's 3GB range covers 2.4–241.7 m³/h with oil temperatures up to 350°C.
