Genuine Wilo spare motor, part number 2186384. The RMOT replacement motor module for a Wilo Stratos MAXO-Z 25/0,5-8 circulator.
Read this before ordering — this is not a complete pump
RMOT stands for replacement motor. Wilo list it as an accessory, not as a pump. It is the service part you fit to a pump housing that is already in the pipework and still sound.
If your pump has failed and you need the whole thing, this is the wrong item — talk to us and we will supply the complete circulator instead.
What you get
- Electric motor and electronics module
- Motor housing, IPX4D
- Threaded cable connections
- Fitting kit — O-ring and four motor fastening screws
What you do not get
- No pump housing
- No impeller
- No unions, cabling or controls
When the spare motor is the right call
On a MAXO-Z the housing is the expensive part — the Z models use a corrosion-resistant housing because they circulate drinking water. If that housing is sound and it is the motor or electronics that have failed, fitting an RMOT restores the pump for less than a full replacement, and without cutting into the pipework.
Choose the complete pump instead if:
- The housing is corroded, cracked or scaled
- The pump is being moved or the pipework reworked
- You are not certain what failed
Check the model before you order
An RMOT is matched to one specific pump. This one fits the Stratos MAXO-Z 25/0,5-8 and no other. Read the model off the pump's own nameplate — not off the invoice, not off the old paperwork — and send it to us if there is any doubt. At this price it is worth the extra minute.
