Mnogo je čimbenika koje treba uzeti u obzir pri odabiru aksijalna pumpa s podijeljenim kućištem i impeler ispravno. 

Prvo, moramo znati gdje se tekućina treba transportirati i kojom brzinom protoka. Potrebna kombinacija visine i protoka naziva se radna točka. Radna točka izravno je povezana s potrebnom geometrijom rotora. Primjene s dugim okomitim pumpanjem (visoka visina) zahtijevaju rotore većeg vanjskog promjera od aplikacija s kratkim okomitim pumpanjem (pumpanjem).

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.

Jedan od najčešćih impelera za rukovanje krutim tvarima je otvoreni rotor. Ovaj impeler se obično koristi u pročišćavanju kanalizacije i otpadnih voda i ima geometriju koja uključuje prolaze između lopatica s otvorenom stranom okrenutom prema ulazu. Razmaci između lopatica osiguravaju nesmetan put rotoru za potiskivanje ulaznih krutih tvari iz usisnog otvora rotora u spiralu i konačno kroz ispuh crpke.

Druga opcija za rukovanje krutim tvarima je vrtložni ili udubljeni rotor. Ova vrsta rotora montirana je unutar kućišta (stvarajući veliki otvoreni prostor između rotora i usisnog priključka) i potiče gibanje tekućine kroz vrtloge stvorene brzom rotacijom rotora. Iako ovaj pristup nije toliko učinkovit, pruža mnoge prednosti za prolaz krutih tvari. Glavne prednosti su veliki slobodni prostor i minimalna prepreka prolazu krutih tvari.

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.
