AMT 368B-95 Cast Iron Straight Centrifugal Pump, 1/2 HP
When you need a pump that can run day after day without drama, the AMT 368B-95 earns its keep. Built with a durable cast iron housing and a stainless steel impeller, this 1/2 HP straight centrifugal pump is made for continuous-duty, low-pressure work across industrial, commercial, and general service settings. It handles everything from circulation and liquid transfer to chemical processing and dirty water applications, making it a versatile choice for shops, plants, and facilities that need dependable fluid movement without constant maintenance calls.
What sets this pump apart is its practical, service-friendly design. The self-cleaning, semi-open impeller resists clogging and can pass solids up to 1/8" in diameter, so it keeps working even when the liquid isn't perfectly clean. A pull-from-rear design means technicians can service the pump without disturbing the connected piping, saving time and hassle during routine maintenance. The Buna-N mechanical seal and O-ring construction are matched to the cast iron body, and the discharge port rotates in 90° increments so installers can orient it to fit the space they're working with.
Powered by a TEFC single-phase motor running on 115/230 VAC, the 368B-95 is close-coupled for a compact footprint and reliable performance. Keep in mind this pump is not self-priming and requires flooded suction to operate properly. With a 3/4" inlet and 1/2" outlet, a maximum working pressure of 75 psi, and a maximum operating temperature of 180°F, it's a solid fit for anyone who needs an affordable, no-nonsense centrifugal pump that just keeps running.

Frequently Asked Questions
Q: Can the AMT 368B-95 run dry without damage?
No, this pump is not self-priming and must have flooded suction at all times. Running it dry can damage the mechanical seal and impeller.
Q: What voltage options does the 368B-95 support?
It operates on 115/230 VAC single-phase power, giving flexibility depending on the electrical setup available at the installation site.
Q: How much solid debris can this pump handle without clogging?
The self-cleaning, semi-open impeller is designed to pass solids up to 1/8" in diameter, making it suitable for mildly dirty or debris-laden liquids.
Q: Is the discharge port adjustable during installation?
Yes, the discharge port rotates in 90° increments, allowing installers to position it to match existing piping layouts.
Q: What is the benefit of the pull-from-rear design?
It allows technicians to access and service internal components like the seal and impeller without removing the pump from its connected piping, reducing downtime.
