Definition
La diferencia máxima permisible entre la presión absoluta del líquido en el puerto de entrada y la presión de ambiente absoluta. Cálculo: limitado por los mismos factores que la Presión de funcionamiento máxima permisible (MAWP, por sus siglas en inglés).

Maximum allowable inlet pressure, also known as maximum allowable suction pressure (MASP), is the maximum allowable difference between the absolute pressure of the fluid at the inlet port and the absolute ambient pressure.

Maximum allowable inlet pressure can be established as the lowest pressure limit of the following 3 components:
1) Shaft Seal
2) Joint Seals
3) Port Connections

 

Image showing the pump and system components that are used to calculate the maximum allowable inlet pressure. The lowest pressure limit of these three locations will equal the MASP.

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