Galley Maid MR-10/150 Stator — OEM-Compatible Replacement for Dual-Model Pump Fit
When a Galley Maid pump starts losing pressure or stops moving fluid effectively, the stator is almost always the first component to inspect. The MR-10/150 Stator is the genuine replacement rubber stator designed to fit both the MR-10 and the #150 pump configurations — two of the most widely used models in Galley Maid's lineup. It seats snugly around the brass rotor inside the pump's nose housing, creating the tight seal necessary for the pump to build and hold pressure. Over time, rubber stators can harden, crack, or degrade — especially after periods of dry running — and replacing them is the single most effective step in restoring full pump performance.
Installation is straightforward for anyone comfortable doing basic pump maintenance. On the MR-10, the stator flange must be pressed firmly into the groove in the pump base before the nose housing is reattached with its six machine screws, tightened evenly in a uniform pattern. A small amount of silicone grease applied to the stator's interior and the rotor surface before reassembly makes seating easier and helps protect against premature wear. This single part can save the cost of a full pump replacement and get a system back up and running in a fraction of the time.

Frequently Asked Questions
Q: What is the difference between the MR-10 stator and the #150 stator, and why do they share the same part number?
The MR-10/150 designation indicates that a single stator part fits both the MR-10 and the #150 pump configurations. Galley Maid uses a shared stator geometry across these two models, which simplifies parts inventory and means one replacement covers both applications.
Q: How do I know if my stator needs to be replaced versus another pump component?
If the pump motor runs normally but the system fails to build pressure, the stator is the most likely cause. Remove the nose housing and inspect the rubber stator — it should fit snugly over the brass rotor with no visible cracking, hardening, or internal roughness. Damage from dry running typically shows as scoring or stiffening of the rubber interior.
Q: Can I reinstall the same nose housing and hardware when replacing the MR-10/150 stator?
Yes. The replacement stator is designed to seat into the existing pump base groove and work with the original nose housing. On the MR-10, six machine screws secure the nose housing after the new stator is seated — no new housing or hardware is required in most cases.
Q: Should I replace any other parts at the same time as the stator?
It is strongly recommended to replace the water seal at the same time as the stator. Galley Maid's universal seal set fits all pump models in the lineup, including the MR-10 and #150. Replacing both the stator and seal during the same service interval maximizes pump longevity and avoids a repeat teardown shortly after.
Q: What lubrication should be used when installing the MR-10/150 stator?
A small amount of silicone grease applied to the stator's interior bore and the rotor surface before reassembly is the correct approach. Do not use motor oil or petroleum-based grease, as these can damage the rubber stator material and compromise the seal against the rotor.
