AMT 3700-011-09 Bronze Impeller for 3/4 HP Three-Phase Pumps
When a centrifugal pump starts losing flow or running rough, the impeller is often the first place to look, and the AMT 3700-011-09 is built to solve exactly that problem. This machined bronze impeller is engineered as a direct-fit replacement for AMT pumps powered by a 3/4 HP three-phase motor, restoring the smooth, consistent flow the pump delivered when it was new. Bronze construction was chosen for its resistance to corrosion and wear, which matters most in pumps that see regular use moving water or mildly aggressive fluids in industrial, agricultural, or commercial settings.
Beyond just fitting the pump housing, this impeller is precision-machined to keep tight tolerances between the impeller vanes and the pump casing. That close fit is what keeps efficiency high and vibration low, so the pump doesn't have to work harder than it should just to move the same amount of liquid. For technicians and facility managers handling routine maintenance or rebuilding a pump after years of service, swapping in a properly matched impeller like this one is one of the most cost-effective ways to extend the working life of the equipment rather than replacing the entire pump.
Because it is designed specifically for the 3/4 HP three-phase configuration, this part is a straightforward match for anyone who already knows their pump's horsepower and motor phase, taking the guesswork out of the repair. Whether the pump is part of a water transfer system, a processing line, or general industrial fluid handling equipment, having the correct impeller on hand means less downtime and a quicker return to normal operation.

Frequently Asked Questions
Q: How do I know if this impeller is the right fit for my AMT pump?
A: Match the part number and motor specifications, including the 3/4 HP rating and three-phase configuration, against your pump's existing impeller or nameplate data before ordering.
Q: Can this impeller be installed without professional help?
A: Many users with basic mechanical skills and the correct tools can replace it themselves, though following the pump's service manual and disconnecting power beforehand is essential.
Q: What are the signs that an impeller needs to be replaced?
A: Reduced flow, unusual noise, loss of pressure, or visible wear and pitting on the impeller vanes are common indicators that a replacement is needed.
Q: Is bronze a good material choice for this type of impeller?
A: Yes, bronze offers strong resistance to corrosion and wear, making it a durable choice for pumps used in regular industrial or commercial fluid handling.
Q: Will this impeller work with pumps outside the AMT product line?
A: It is designed specifically for compatible AMT pump models, so fitment on other brands is not guaranteed without verifying compatible specifications first.
