MACP

Classification

Definition

Pressione nominale massima dei componenti della pompa che contengono pressione, esclusa la tenuta dell'albero, ma compreso il contenitore nel caso delle pompe Mag Drive.
Calcolo: il MACP può essere stabilito come il limite di pressione dei raccordi di collegamento per la maggior parte dei modelli di pompa. Nel caso delle pompe Mag Drive, può essere considerato come il limite idrostatico del contenitore diviso per 1,5.

What is maximum allowable casing pressure (MACP)?

Maximum allowable casing pressure is the maximum rated pressure of the pressure containing components of the pump. This rating does not include the seal. However, this rating does include the canister in Mag Drive pumps.

How to calculate maximum allowable casing pressure

Maximum allowable casing pressure (MACP) can be established as the pressure limit of the port connections for most pump models. In the case of Mag Drive pumps, it can be considered as the hydrostatic limit of the canister divided by 1.5.

Why is knowing maximum allowable casing pressure important?

Knowing the maximum allowable casing pressure is important so that the pump is operated safely. Exceeding the MACP can lead to damaging the pump or system.
