Definition

Differenza massima consentita tra la pressione assoluta del fluido alla porta di ingresso e la pressione assoluta ambiente.
Calcolo: limitato dagli stessi fattori della pressione massima di esercizio consentita (MAWP).

What is maximum allowable inlet pressure (MASP)?

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.

How to calculate maximum allowable inlet 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.

Why is knowing maximum allowable inlet pressure important?

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.
