I have to say that An Pump is a supplier I am willing to cooperate with, and their pump quality is very stable. There will be a batch of orders every once in a while. They not only give me peace of mind in terms of pump quality but also provide timely after-sale services. Moreover, in the past few years, I have gained a lot of knowledge about pump technology.
Although the pump is not the most economical in dollar terms, I have found them to be the most professional person to deal with. I will admit, there is another very close competitor. All that said, respectfully, I 'd like to cooperate with An Pump because working with them makes me feel very comfortable, they will tell you truthfully what can be done and what can’t be done, so I feel at ease.
I have bought pumps in a couple of other China sources but this company seem special. Min order for bronze cast is 10 units to justify the pour but they accommodated the smaller order without changing the price. Short lead time of 40 days for custom built pumps and about half of what you pay for equivalent in say regent but without stainless base.
