Insulated Well Pump Cover · ~R-7 Foam Core · 4 Sizes

This insulated well pump cover is built around a closed-cell urethane foam core rated at approximately R-7. It traps ground and equipment heat around the pump, wellhead, and pressure tank, protecting against freeze damage through cold snaps from the southern Carolinas to the upper Midwest. The insulation is wrapped in a layered fiberglass shell and finished in a 20-mil pigmented gelcoat that never needs painting. It comes in four sizes.

Overview

Insulated to Stand Up to Hard Freezes.

This insulated well pump cover puts a closed-cell urethane foam core (approximately R-7) between the cold and your pump, wellhead, and pressure tank. That insulation traps ground and equipment heat around the equipment, protecting against freeze damage across a wide climate range — while the layered fiberglass shell and 20-mil pigmented gelcoat stand up to UV, weather, and the everyday abuse of being out in the yard without ever needing paint.

Four sizes cover everything from a single wellhead with a compact pump up to larger wellhead, tank, and pump groupings. Snap-tight construction means no fasteners are required for routine service — lift it off, work the pump, set it back down. No anchoring hardware is needed for normal use; the shell's weight and shape hold it in place.

Why Contractors Specify It

Freeze Protection That Holds Up Outdoors

~R-7 foam core

A closed-cell urethane foam core shields the pump, wellhead, and pressure tank through cold snaps from the southern Carolinas to the upper Midwest.

Snap-tight, no fasteners

The cover lifts off and sets back on for routine service — no bolts or hardware to manage in the field.

Gelcoat that lasts

A 20-mil pigmented gelcoat resists UV and weather and never needs painting — stackable for distributor freight efficiency.

FAQ

Common Questions

How does the insulation protect the pump?
The shell is a layered fiberglass exterior over a closed-cell urethane foam core (about R-7). That insulation traps ground and equipment heat around the pump, wellhead, and tank, protecting against freeze damage across a wide climate range. In severe cold, some owners add a thermostatically controlled heat source inside the cover.
What size insulated well pump cover do I need?
Measure the footprint and height of your pump, wellhead, pressure tank, and any backflow components together, then add clearance. The Small Standard (18″ L × 18″ W × 22″ H) covers a single wellhead, small pressure tank, or compact pump. The Small-Medium Standard (33″ L × 22″ W × 24″ H) fits a wellhead plus a small tank or dual-line setup. The Medium Standard (40″ L × 35″ W × 38″ H) handles a full wellhead-and-tank install, and the Large Standard (58″ L × 34″ W × 44″ H) covers larger wellhead, tank, and pump groupings.
Does the cover need to be painted or anchored?
No painting — the color is a 20-mil pigmented gelcoat molded into the shell. For routine installs no fasteners are required; the snap-tight design lifts off for service and sets back down. Anchoring kits can be added where high wind or tampering is a concern.
What casing sizes does it fit?
All four sizes fit 4″ to 12″ casing diameters as standard. Custom configurations are available on request — contact us if your installation falls outside the standard range.
