The Chemtainer SE-250-R is a molded plastic pump house vault in black, built to shelter well pumps, pressure tanks, backflow assemblies, and pump controls from weather, sun, and casual tampering at above-ground installations. This is a protective enclosure, not a storage tank, so it carries no gallon, outlet, or lid spec by design. What matters is fit: the footprint is 24 x 24 inches with a 28-inch overall height, and the empty shell weighs just 30 pounds, light enough for one person to hand-place over an existing pump group with no equipment.
Will it fit over my pump assembly?
Vertical clearance stops more installs than footprint, so check height first: confirm the 28-inch overall height clears the tallest point of your pressure tank or manifold. Then verify the equipment fits inside the 24 x 24-inch footprint with room for connections, and set the vault on a level, well-drained base so it stays square and seals against wind and pests. The specs read light on purpose - dimensions are verified, but there is no capacity, outlet, or lid number because this is a house for equipment, not a vessel. If you are pouring a fresh pad, our concrete pad sizing guide walks through the ACI framework for above-ground polyethylene equipment.
Cold-climate and rural service
A black plastic pump house earns its keep where freeze protection matters. On rural wells, private fire-protection skids, and remote pressure sets, the closed shell gives you an insulatable enclosure around the pump and its plumbing. Pair it with your own heat source and insulation; our rural fire-water reservoir design guide covers the freeze-protection engineering that keeps a private fire or well stack running through cold-climate winters. Review the technical drawing on this page for the exact molded dimensions before you frame in any heater or utility penetrations.
The mistake to avoid
Do not treat this vault as a water container. It is an unrated protective house with no outlet, fitting, or capacity, so any plumbing penetrations must be cut and sealed by you to suit your pump group. Lay out the interior around your specific pressure tank and controls before ordering, and if you are still selecting the pump-and-tank package it shelters, the Tank Sizing Calculator and Tank Sizing Guide help you spec the system this enclosure will protect.
