Pump Operations
Tandem Pumping
Tandem pumping is using two engines together to feed a high-pressure or high-volume demand a single pump cannot meet alone. It is a way to stack capacity when one apparatus runs out of pump.
Some demands — a long high-rise standpipe or a big master stream over distance — exceed what one engine can supply. Working two pumps in concert raises the available pressure or flow beyond a single pump's ceiling.
It is an advanced supply tactic that depends on a strong source and careful coordination. The principle is the same as a relay: combine pumps so no single one is overdrawn.
