Gear Pump Koshin GL 20-5

Gear Pump Koshin GL-20-5 widely use 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 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
