MACP
Classification
Definition
Högsta klassade tryck för pumpens trycksatta komponenter, exklusive axeltätningen men inklusive behållaren i höljet för pumpar med magnetisk drift
Beräkning: MACP kan fastställas som tryckgränsen för portanslutningarna för de flesta pumpmodeller. För pumpar med magnetisk drift kan det anses vara behållarens hydrostatiska gräns delat med 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.
