I believe so. Take look at the
Energy Star website. This page shows all 3.0 HP pumps from Asia Connection under different brand names including Calimar, Circupool and B&D. You can select and compare the different pumps and all will show identical specs. Then search each pump individually and compare photos and owners manuals (if you can find them). You'll see identical diagrams, part numbers, and language.
One positive note is that there are parts available for the
Calimar Pump (click the parts tab), including a new drive and motor. If things go wrong, you might be able to repair the pump.
