MAWP

Classification

Definition

Pression maximale continue pour laquelle la pompe est conçue.
Calcul : la MAWP peut être établie comme la limite de pression la plus basse des 3 composants suivants:
1) Joint d'arbre
2) Joints de raccord
3) Raccords de port

What is maximum allowable working pressure (MAWP)?

Maximum allowable working pressure (MAWP), is the maximum continuous pressure for which the pump is designed to handle.

How to calculate maximum allowable working pressure?

Maximum allowable working 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 working pressure. The lowest pressure limit of these three locations will equal the MASP.

Why is knowing maximum allowable working pressure important?

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