Does anyone know anything about pipeline pumps?

There is very little knowledge about pipeline pumps in books and online. Please know the prawns and give me some advice! Thanks!
As the name suggests, pipeline pumps are installed on pipelines. Small pumps do not require a foundation and mainly function as a booster.
Pipeline pumps are divided into two types: direct-coupled pipeline pumps and non-direct-coupled pipeline pumps. Non-direct-coupled pipeline pumps are driven by a coupling with an intermediate shaft. The rotor set (including: impeller, pump shaft, bearings and Shaft seal, etc.) for maintenance, it is more suitable for chemical production, especially for large-scale chemical equipment applications. In addition, the pipeline pump has the advantage of small footprint. If it is designed, manufactured and inspected according to the standards and specifications of centrifugal chemical process pumps, it can be developed into a pipeline chemical process pump. Pipeline pumps are mainly used in chemical production for liquid transfer pumps, relay (boost) pumps, circulation pumps, etc. that are directly installed on equipment or pipelines.
The pipeline pump used in the hydraulic coupler of the granulator in my unit is interlocked with the equipment in the pipeline and cannot be seen from the outside.
Pipeline pumps are a type of centrifugal pump. They are generally installed vertically. They are characterized by a smaller footprint. The disadvantage is that they are not as maintainable as horizontal centrifugal pumps. Pipeline pumps are the same as centrifugal pumps. Different design standards determine their different application situations. Most pipeline pumps are used in municipal administration, plumbing, water supply and drainage, etc. These pumps are generally * * Designed according to standards or industry standards, the technical requirements are relatively low and the price is also low. There are also some pipeline pumps used in chemical industry, oil refining and other industries to transport flammable and explosive media. These pumps should be designed according to API 610 standards, which have higher requirements and higher prices. In order to solve maintenance difficulties, pipeline pumps that comply with API 610 standards should be designed with an easily detachable structure. Direct connection is not allowed. Mechanical seals, bearings and other components can be removed for inspection without disassembling the motor and pipelines. Slightly larger pump shafts and impellers should also be removed for inspection.
Thank you all! Gained knowledge! But I read in some books that there are centrifugal and axial flow pumps for pipelines, so I was confused! Also, is the power and flow rate of the pipeline pump not too large?
