AMT 4294-98 Stainless Steel Self-Priming Pump, 1 in., 1/3 HP
The AMT 4294-98 is a compact, hardworking self-priming pump built for anyone who needs to move liquids without babysitting the equipment. Cast from investment-cast 300-series stainless steel, this pump is designed to hold up against corrosive and chemically aggressive fluids, including liquids and chemicals with specific gravities up to 1.6. Its 1/3 HP single-phase motor runs on 115/230V power, giving it enough muscle for light-to-moderate transfer jobs while staying easy on energy use. Whether it's set up in a workshop, processing facility, or utility room, this pump is meant to be installed once and forgotten about—until you actually need it to run.
What makes this pump dependable day to day is its combination of a Viton mechanical seal and O-ring with a self-cleaning, semi-open impeller. That pairing means it can handle liquids carrying dissolved solids or light debris without seizing up or losing efficiency over time. The pump self-primes to 6 feet, so it doesn't need to sit flooded or be manually primed before every use, which saves real time in applications where the pump isn't running constantly. With 1-inch NPT suction and discharge ports, it fits neatly into standard piping setups without requiring special fittings or adapters.
Beyond the technical details, this is a pump built for consistency. Its open drip-proof (ODP) motor and rugged stainless housing are meant to keep performing through repeated start-stop cycles, seasonal use, or continuous operation in demanding environments. For anyone comparing self-priming pumps for chemical transfer, industrial fluid handling, or general liquid transfer where corrosion resistance matters, the AMT 4294-98 offers a straightforward, low-maintenance option that's ready to install right out of the box.

Frequently Asked Questions
Q: Can the AMT 4294-98 run dry without damage?
A: No, this pump is not designed for prolonged dry running. It should always be primed with liquid or allowed to self-prime within its rated 6-foot lift before extended operation to avoid seal and impeller wear.
Q: Is this pump suitable for outdoor installation?
A: The ODP (Open Drip Proof) motor is best suited for indoor or sheltered locations. For outdoor use, additional weather protection or a covered enclosure is recommended to protect the motor from moisture exposure.
Q: What kind of maintenance does this pump require?
A: Routine maintenance is minimal. Periodically inspect the mechanical seal for wear, check that the impeller area is free of debris buildup, and confirm electrical connections remain secure and corrosion-free.
Q: Can this pump be used with three-phase power?
A: No, the 4294-98 is built specifically for single-phase 115/230V power. Anyone needing three-phase compatibility would need a different model within the AMT self-priming pump lineup.
Q: How does this pump compare to higher-horsepower models in the same series?
A: The 4294-98 is the lowest-horsepower option in its stainless steel self-priming series, making it ideal for lighter-duty transfer tasks, while higher HP variants in the same body style are better suited for higher flow or head requirements.
