Which company in China does a good job in producing AY-type oil pumps?
The originator should be Shenyang Pump Factory, but there were many others first. Shenyang Pump Factory, Shenyang Grid Pump Factory, Zhejiang Jialite Pump Factory, and Keer Pump Factory are all good options.
When it comes to pumps, those from the old industrial bases in the Northeast are of better quality; pumps from the Jiangsu and Zhejiang regions are not as durable and have a higher rate of needing repairs. Our practical experience!
The pumps from Shandong Changzhi Pump Industry that we use are also good
Personally, I think Shenyang Pump Factory is better, as its quality is guaranteed. The drawings for domestic pumps come from Shenyang, but after modification, the components can no longer be used interchangeably. For example, are there pumps made of 316L material available in China? If you ask some small factories, they will surely claim that they can do it, but Shenyang Pump Factory will tell you that they can’t; our 1CR18 material is even better than theirs. This is indeed the case in real-world usage.
Was Shen Pump merged into Shen Gu?
Zhejiang Jialite Pump Factory, Cole Pump Factory.
Shenyang Pump Factory is the pioneer. The rest are counterfeit manufacturers.
Which ones in Shandong Province are performing well?
Shandong Changzhi Pump Industry. Yantai Corrosion-Resistant Pump Factory.
Considering both investment and usage, Grid’s performance is quite good. For the relatively important pumps in our equipment, we use Graded brand ones; for those with lower requirements, we use Changchun Bet brand ones.
