Morning
I have a Jandy Stealth 2 HP pump that I replaced the motor 3-4 years ago with a Centruy st1202. I'm reconfiguring the fountain and need more water flow. There is little to no space to put in a larger pump. Will a Century 3 HP motor fit on the Jandy housing. And with a best guess would it push a good bit more water.
Thanks

A 3HP motor will fit where a 2HP motor did but it won't change the output of the pump unless you also change the impeller and, possibly, the diffuser as well. Both of these parts are rated by the horsepower they are designed to handle. The impeller definitely needs to be replaced whenever changing the pump horsepower, whether lower or higher. Diffusers typically cover a range of horsepower ratings. For example, when looking up the diffuser for your particular pump model, you might see one listed for .75 – 2 HP and then another for 2.5 – 3 HP. If the new motor falls within the range of your existing diffuser, you can reuse it.
Also, be sure that your plumbing and filter can handle the increased flow before you upgrade.
