MGO PUMP Demonstration test
Demonstration continues running of our three spindle screw pump (our model: GH-R3B) which is designed for transfer of Low sulfur oil for marine 【MARINE GAS OIL】 had been finished. It's total running time is 20hours (10+10 hours).
The pump mechanism is allied balance type to reduce bearing stress which is gotten patent.The kerosene which is worse lubrication than 【MARINE GAS OIL】 (HFRR※1) was used in the examination from the problem in acquisition.
This test made it confirm the performance under witness by owners who have relation on 2009.12.02.
This pump is sold and manufactured as a pump for MGO.
