An installation-first shortlist
Crawl-space dehumidifiers with a built-in pump
A focused shortlist for drain routes that need pumping.
A built-in pump can help when the drain route cannot stay downhill. Start here, then verify the actual discharge route and limits in the exact product manual.

AlorAir Sentinel HD55P
A built-in-pump option for installations where a downhill drain is not available. The headline 120-pint figure is a hot, humid saturation rating; the same page lists 55 pints at 80°F and 60% RH.
Confirm the route before the rating
The HD55P is a pump-equipped model. Confirm vertical lift, hose limits and the drain destination before buying. A pump feature is not evidence that every route will work.
Consider an external pump too
A gravity unit with a separate condensate pump may be another option. Compare the total installation cost and service access rather than assuming an integrated pump is always preferable.
