Changing Shaft Rotation While Maintaining Suction Ports
Models 4312-4316
To maintain the same suction port and yet change shaft rotation from clockwise to counter-clockwise or vice versa please do the
following.
• Looking at the pump from the shaft end with the ports up, note the location of the V notch in the bracket
• If at the top (12 o’clock), rotation is clockwise
• If at the bottom (6 o’clock), counterclockwise
• Remove the cover screws so that the cover moves freely
• Rotate the cover 180°
• Align the mounting holes and reinstall the cover screws making sure the seal gland is vented to the suction side of the pump
