Kuna mambo mengi ya kuzingatia wakati wa kuchagua pampu ya mgawanyiko wa axial na impela kwa usahihi. 

Kwanza, tunahitaji kujua ni wapi maji yanahitaji kusafirishwa na kwa kiwango gani cha mtiririko. Mchanganyiko wa kichwa na mtiririko unaohitajika huitwa hatua ya wajibu. Hatua ya wajibu inahusiana moja kwa moja na jiometri ya impela inayohitajika. Programu zilizo na pampu ndefu ya wima (kichwa cha juu) zinahitaji vichocheo vikubwa vya kipenyo cha nje kuliko programu zilizo na pampu fupi ya wima (kusukuma).

Another consideration that is directly related to impeller size is the expected solids content in the application. Many applications have a variety of solids in the pumped media. These solids can range from small abrasive debris such as sand or metal shavings to fine fibrous materials to large solids the size of a baseball or larger. The pump and impeller selected must be able to pass these solids while avoiding clogging and damage from wear. Additional consideration must also be given to the equipment downstream of the axial split case pump. While a pump can be selected to pass a specific type of solids, it cannot be assumed that the downstream piping, valves, and other process equipment will have the same solids handling capabilities. Knowing the expected solids content in the liquid is critical not only to selecting the right size pump and impeller, but also to selecting the impeller style that best suits the application.

Mojawapo ya vitu vikali vya kushughulikia viboreshaji ni msukumo wazi. Msukumo huu hutumiwa kwa kawaida katika matibabu ya maji taka na maji machafu na ina jiometri inayojumuisha vifungu kati ya vile na upande wa wazi unaoelekea mlango. Nafasi kati ya vile vile hutoa njia laini kwa kisukuma kusukuma yabisi inayoingia kutoka kwa shimo la kufyonza cha impela hadi kwenye volute na hatimaye kupitia utiririshaji wa pampu.

Chaguo jingine la kushughulikia vitu vikali ni vortex au impela iliyowekwa tena. Aina hii ya impela imewekwa ndani ya casing (kuunda nafasi kubwa ya wazi kati ya impela na bandari ya kunyonya) na inaleta mwendo wa maji kupitia vortices iliyoundwa na mzunguko wa haraka wa impela. Ingawa mbinu hii haina ufanisi kama huo, inatoa faida nyingi kwa kifungu cha yabisi. Faida kuu ni nafasi kubwa ya bure na kizuizi kidogo kwa kifungu cha yabisi.

Pumps used at high altitudes have their own set of solids handling considerations. Since these applications typically use smaller piping, the solids passage size of the entire system must be considered, not just the pump. Typically, the axial split case pump manufacturers offering high-pressure pumps will include a strainer at the inlet to prevent large solids from entering the pump. 

This is ideal for high-pressure applications where minimal solids are expected, but can cause clogging if enough solids accumulate around the screen surface.

There are many factors to consider when choosing the right axial split case pump and impeller, and understanding the various styles of pumps and impellers is often one of the most critical steps.
