Centrifugal Pumps - Minimum Flow

Centrifugal pumps and minimum continuous flow

A catastrophic failure of a centrifugal pump can occur if the liquid within the pump casing is allowed to vaporize. To prevent flashing due to overheating of the fluid, a flow must be maintained through the pump to keep the liquid below saturation temperature.

If a temperature rise of 15 oF is accepted in the casing - minimum flow through a centrifugal pump can be calculated as

q = PBHP / 2.95 cp SG         (1)

where

q = minimum flow rate (gpm)

PBHP = power input (BHP)

cp = specific heat capacity (Btu/lb oF)

SG = specific gravity of the fluid
