The domestic technology for high-pressure plunger pumps for urea (liquid ammonia and methylammonium) is now very mature. I would like to know what are the differences between similar foreign plunger pumps and domestic ones? Especially in terms of operation and maintenance costs and one-time investment? Is there any domestic supply agency for foreign high-pressure plunger pumps for urea? Thank you Haiyou for your advice! !
I searched online, but the price was ridiculously expensive.
Centrifugal pumps are already available.
Domestic equipment can meet production requirements.
The plunger pump has a short operating cycle and high maintenance costs. Nowadays, high-pressure centrifugal pumps (made by Ebara, Japan) are used. Why do we still need to use a plunger pump?
1st poster: Do you want to update the original equipment or build a new device? If you build a new urea device, it is best to use a centrifugal pump. Although the one-time investment is large, the operation is stable and the energy consumption is low. Foreign centrifugal pump manufacturers include: Ebara of Japan, Sanctum of the United States, New Billon of Italy, etc. , their pumps are all running in China, but it is said that Ebara's are more reliable. There are currently four "Ebara" ammonia/methane ammonium pumps in East China. They will be put into operation in the autumn. We will go and have a look then. Pumps are imported from abroad in Beijing. There are agents in Shanghai, and the price is about several million per unit.
At present, all high-pressure ammonia pumps are centrifugal. Why choose the plunger type? The plunger packing of plunger-type ammonia pumps often leaks. Since EBARA produces centrifugal high-pressure ammonia pumps, it is recommended not to use a plunger pump.

Bologna, Italy, prices are not low.

Japan's Ebara high-pressure centrifugal pump is easy to maintain and has a long operating cycle. High-pressure plunger pumps are troublesome to maintain and have a short operating cycle.
We use high-pressure centrifugal pumps from Ebara, Japan.
Please ask Farway Haiyou: How effective is your high-pressure centrifugal pump? How is the flow rate adjusted? Does the pump outlet pass through a throttle valve or is it controlled by frequency converter? 13#forway
Most of the large urea plunger pumps abroad are centrifugal or vertical seven-link plunger pumps.
