Multistage ring section pump
Pump category
Pump selection tips
All multistage pumps mentioned here are ring section pumps with redially split case. When we say multistage pump, we usually mean the multistage ring section pump although we have multistage axially split case pump. The engineers from some countries may dirrectly call it ring section pumps. We have to clarify it here in order to avoid misunderstanding. These multistage pumps are designed according to ISO standard and API610 standand.
HM type is the basic multistage ring section pumps that is the most common multitage pump that is used for clean water at different temperature. Now, we have the new generation HM multistage pump. The new generation HM multistage ring section pump has nice feature, optimizde performance, flexible nozzle orientation, etc.. It must be the best multistage pump at world class design and quality.
HMB multistage ring section pump and HMC multistage ring section pump are in compliance with API610 standard. HMB multistage pump have the back-to-back stacked impellers to automatically balance the axial hydraulic thrust. HMC multistage pump has similar working principal with HM type multistage ring section pump, but HMC multistage is designed according to API610 standard BB4 type. Untill now, we wish you have rouch idea about the difference between the four types of multistge ring section pump.
HMC type (BB4) horizontal multistage ring section high pressure pump
HMC type is the horizontal multistage ring section pump and high pressure pumps that is designed according to API610 10th. The impellers are stacked in the same direction on the pumps shaft. The rotor is balanced by the specially designed balance drum device. The rotors are perfectly dynamically balanced and the maximum stages can be up to 16stages. HMC type API610 BB4 multistage ring section pump is the ideal high pressure pumps for water feeding, boiling water, petroleum oil, chemical liquid, etc..
