Sta-Rite L76-37P Pump Casing
The Sta-Rite L76-37P is a replacement pump casing. This is the main housing that the impeller, diffuser or volute, and seal all mount inside, and it carries the suction and discharge ports that connect the pump to the plumbing.
Because the pump casing sets the alignment for the impeller and seal, a warped or cracked one can cause premature wear on both even if they are otherwise in good condition. Check the mounting bosses and port threads on the old part for damage in addition to obvious cracks before ordering.

Frequently Asked Questions
Q: Does this come with mounting hardware?
This listing is for the pump casing itself. Reuse the original mounting bolts if they are in good condition, or order new ones separately if they are corroded or stripped.
Q: Can a cracked pump casing be repaired with epoxy?
A pressure-holding part like this should be replaced rather than patched. An epoxy repair may hold briefly but is not reliable under the pressure and vibration of normal pump operation.
Q: How do I prevent this from cracking again?
Drain the pump before a hard freeze, or keep it in a heated space, and make sure the pump is not run dry, which stresses the housing along with the internal parts.
Q: What usually causes a pump casing to need replacing?
A hard freeze while the pump was full of water is the most common cause, followed by age-related stress cracking and impact damage. A leak at the body itself, rather than at a fitting, is the usual symptom.
