How to choose a pump
Thread Content
Which one should be chosen between the ZA and ZE series of pump models? Their performance curves are the same – so how can a reasonable choice be made based on the medium and cost factors?
I also found that some oil pumps come in ZA, ZE, and AY series – how do I choose which one to use?
ZA for foot support, ZE for central support; it’s applicable to rotor components in general, but the pump body varies as does the pressure rating.

The operating temperature for ZA generally does not exceed 170 degrees, while ZE can reach 400 degrees. The operating pressure for ZA shall not exceed 2.5 MPa, and the operating pressure for ZE shall not exceed 5 MPa. The operating temperature of AY can reach 400 degrees, while the operating pressure depends on the pump model: smaller pumps can handle up to 4 MPa, whereas larger pumps can handle up to 6.3 MPa.
Is the selection of these three types of pumps related to the properties of the medium they handle? Such as oils, acids, bases
It has no direct relation to the medium; those medium properties affect the material of the pump, but have little impact on the pump’s model or series.
