How to choose the model and specification of oil pump

Install it on the machine according to the original factory specifications, so that the machine can work in the best condition! You should choose Yaer gear oil pump as the oil pump. The price is average, but the brand is old. Yunnan Lifan and Changzhou Dongfeng all installed this brand! One of my relatives sells oil pumps, so I know them better. He said that Yaer returned the least, and those self-employed people in Wuxi returned the most, and some of them didn't give three guarantees! I hope I can help you!
