Which statement is true about a single-stage pump?

Explanation:
A single-stage pump uses one pumping stage, so there’s no second stage to switch into. Because there’s nothing to transfer between, a transfer valve isn’t part of its normal operation. The transfer valve exists to connect or isolate a second stage in two-stage pumps to boost pressure when needed. So saying a single-stage pump does not require a transfer valve to function is accurate. It can still deliver high pressures appropriate to its design, and single-stage pumps are commonly used in firefighting.
