The black wire is most likely a Common ground wire, I suggest googling a schematic on the new pump before trying.
get a 2 speed switch and wire it yourself for low and high

Just cap off the black wire, That connects to the low speed windings. Is this motor 115v or 220v?
From your supply power 115v will have a common, a hot, and a ground. Orientation to motor wires/ poles matters.
A 220v will have 2 hot and a ground. Since both line wires are hot, the orientation does not matter.
Make sure you get it right!

can you photograph the new connections for me? if you look at the connections, the neutral normally has a solid link across it, the earth will be to the frame and the other two are the high and low speed live connections.

V1 would be low V2 would be high U1 would be line and then ground. A picture would be helpful to be sure.

You will need to pull the front of the pump off then unscrew the impeller. The impeller will be set on the shaft and will take some force to break free. Hold ing the back of the shaft and using water pump pliers on the face of the impeller will usually work but sometimes I will wedge a screwdriver in the fin of the impeller and hit it sharply (not hard) with a hammer to break it free. Then the housing will just pull free of the motor. When replaceing, the impeller just goes on hand tight. Hope this helps and good luck.

Wire the red and black to the Line 1 connection on the motore, and the blue on the Line 2, Make sure your motor voltage is correct and turn on.
Probably not ... 1725 and 3400 <> are standard speeds for electric motors. See if your dealer will make an exchange for you for the proper speed pump.
