Classification

Definition

Différence maximale admissible entre la pression de refoulement et la pression d'entrée pour un ensemble donné de conditions de fonctionnement.

Calcul : fourni par le programme de sélection de pompe ou les courbes de performance du catalogue, mais peut être augmenté ou diminué en fonction des spécificités de l'application, de la taille de la pompe et de sa construction. Cette valeur peut être inférieure ou égale à la pression de dérivation totale de la soupape de décharge.

What is maximum differential pressure?

Maximum differential pressure is the maximum allowable difference between the discharge pressure and the inlet pressure for a given set of operating conditions.

How do you calculate differential pressure?

Differential pressure is a function of the system and must be calculated or measured. Measurements can be made at the gauge ports near the inlet and outlet ports of the pump.

Differential Pressure = (Outlet Pressure) – (Inlet Pressure)

How do I find my pump's maximum differential pressure?

The maximum differential pressure is provided by Viking Pump’s Pump Selector program or Catalog Performance Curves – but may be increased or decreased depending on the application specifics, pump size, and construction. This may be less than or equal to the full bypass pressure of the relief valve.

Why is knowing maximum differential pressure important?

Knowing the maximum differential pressure is important so that the pump is operated safely. Exceeding this value can lead to damaging the pump or system.
