AMT 3890-10M36JT Bronze Self-Priming 3/4 HP Pump
Moving liquids that would eat through ordinary metal takes a pump built for the job, and the AMT 3890-10M36JT delivers exactly that. Its cast bronze body and stainless steel impeller stand up to a wide range of chemicals and corrosive fluids, while the Viton mechanical seal adds another layer of protection against wear from harsh media. It's not limited to one industry either — this pump shows up just as often on farms handling fertilizers as it does in wastewater plants and general liquid transfer setups.
What makes this pump genuinely useful day to day is how little fuss it requires. Being self-priming means it doesn't need to be flooded before every use, so operators can get a job started faster and with less hassle. The 3/4 HP TEFC motor runs enclosed and fan-cooled, keeping it protected from dust and moisture without sacrificing the flow it needs to move fluid efficiently through the system.
Whether it's bolted into a permanent transfer line or set up for a seasonal task, the 3890-10M36JT is built to be dependable rather than fussy. Its dual volute design helps balance the load on the motor, and the semi-open impeller resists clogging from minor debris, so it keeps performing even when conditions aren't perfectly clean.

Frequently Asked Questions
Q: Can this pump run dry without damage?
Running a self-priming pump dry for extended periods can damage the seal and impeller, so it's best to avoid prolonged dry running even though the pump primes itself quickly once liquid is available.
Q: What kind of liquids is the bronze construction best suited for?
Bronze construction holds up well against a range of mildly corrosive liquids, including many agricultural chemicals and wastewater, making it a solid choice where standard cast iron would corrode too quickly.
Q: Does this pump need a separate priming step before each use?
No, the self-priming design means it can draw liquid up from a lower source on its own, as long as the suction line is properly sealed and the pump has been primed at least once initially.
Q: How does the dual volute design benefit the pump long-term?
The dual volute reduces radial stress on the motor shaft and bearings, which helps extend the working life of the pump under continuous or heavy-duty use.
Q: Is this pump suitable for continuous, all-day operation?
Yes, the TEFC motor and bronze construction are designed for reliable, extended-duty use in industrial and agricultural settings, though routine maintenance checks are still recommended for long service life.
