"You have a legal right to pump at work" is the headline most people hear, and it skips the actual mechanics: how much break time, what kind of space, which employers are covered, and what still depends on your own employer's policy. This is a logistics guide, not legal advice, and not a substitute for your own employer's HR policy or a lawyer if your situation is genuinely disputed.
The PUMP Act (Providing Urgent Maternal Protections for Nursing Mothers Act), in effect since 2022, expanded an earlier federal "Break Time for Nursing Mothers" provision. Federal law generally requires covered employers to provide reasonable break time and a private, non-bathroom space to pump breast milk for up to one year after the child's birth.

The law does not set one fixed number of breaks or minutes per day. It requires break time "as needed," which in practice means enough breaks, of enough length, to actually express milk, roughly every 2 to 4 hours depending on your own supply and pump. This is deliberately flexible rather than a fixed schedule.
Federal law generally requires a space that is shielded from view, free from intrusion by coworkers and the public, and not a bathroom. It does not have to be one dedicated, permanently reserved room; a repurposed space (an office with a lockable door, a converted supply room) can qualify on a given day if it meets those conditions while you're using it.
It also does not need a fridge or sink built in, though many employers provide one anyway as a convenience, not a legal requirement. If you're weighing what to bring with you to make a bare-minimum space workable, seewhat accessories you actually need — a hands-free pumping bra and a way to store milk cold until you get home cover most of the gap.
Most employers are covered. The law includes a limited exemption for very small employers (generally fewer than 50 employees) if compliance would cause significant difficulty or expense for that specific business, evaluated case by case rather than as an automatic pass. Certain categories of workers, including some airline flight crew, fall under separate rules and phase-in timelines rather than the general provision described here.
None of this changes what your own insurance plan does or doesn't cover for the pump itself, which is a separate question. Seehow insurance coverage for the pump actually works for that side of the process. If your employer's accommodation is solid but you're still deciding what to buy, start at the pump-category comparison before narrowing down a specific model.
