Gear Pump Koshin GL-40-5 can be used for kerosene, heavy oil class A/B, lubrication oil. Best suited to force – feed fuel to marine engine and for engine lubrication.
- Same accuracy as as high performance hydraulic pump.
- Most suitable for marine FO, LO
- Low rotating noise guaranteed
Features :
- This high quality pump is applicable for a wide range of activities from low viscosity oil such as kerosene, light oil, etc. To medium/ high – viscosity oil.
- Since the pump has a bypass valve built-in and is equipped with relief function, it is very safe.
Efficiency :
Gear pumps are generally very efficient, especially in high-pressure applications.
Factors affecting efficiency:
– Clearances: Geometric clearances at the end and outer diameter of the gears allows leakage and back flow. However sometimes higher clearances help reduce hydrodynamic friction and improve efficiency.
– Gear backlash: High backlash between gears also allows fluid leakage. However, this helps to reduce wasted energy from trapping the fluid between gear teeth (known as pressure trapping).
