The Chemtainer SE-250-W Pump House (also cataloged as a protective vault) is a white molded enclosure built to shield a well pump, pressure tank, backflow assembly, or valve manifold from weather, sun, and casual tampering at a rural well head or remote water site. This is protective housing, not a storage tank, so there is no gallon rating, specific-gravity number, or resin grade to check, and our data does not list an interior dimension. What matters here is fit and footprint, and both are verified: it stands 28 inches tall over a 24 x 24 inch base and ships empty at about 30 pounds. Confirm the equipment you want to cover clears that footprint and height before ordering.
Will it work for your site?
The SE-250-W is a molded protective shell built to hold up outdoors where a wood or metal box would rot or rust. At roughly 30 pounds empty, one person can lift it off to service the pump underneath and set it back in place. Because it is a cover rather than a sealed vessel, there are no factory-installed fittings, outlets, or lids to specify. One caution on the numbers: the 24 x 24 x 28 figure is the external envelope, so allow for wall thickness when you check that a pressure tank or backflow assembly fits inside, since our data does not include interior clearance. If you are planning how the pump house fits into a larger water setup, our Tank Sizing Calculator and Tank Sizing Guide help you size the storage tank the pump is feeding.
The mistake to avoid
The common error with a pump house is treating it like insulation. This is a protective cover, not a heated or insulated freeze-proof enclosure. In cold-climate service you still need to handle freeze protection separately for the pump, lines, and any pressure tank inside, using heat tape, an added heat source, or below-frost-line plumbing. Our guide on freeze-protection engineering for cold-climate rural sites walks through that discipline. See the technical drawing on this page for the exact profile and dimensions.
Freight and how to order
The SE-250-W ships LTL freight from Hummelstown, Pennsylvania. At 30 pounds and a compact 24 x 24 x 28 footprint it moves easily, but freight is still quoted live to your ZIP rather than folded into the list price. Get a real number in seconds with our Freight Cost Estimator, or call 866-418-1777 and we will match the pump house to your equipment and book the shipment. Buyers often search for this unit as a Chemtainer pump house, pump vault, or white protective pump enclosure.
