AMT 3893-98 SS Self-Priming Centrifugal Pump, 1.5 Inch
The AMT 3893-98 is a stainless steel self-priming centrifugal pump designed for industrial liquid-transfer applications. It combines a 1.5 HP totally enclosed fan-cooled (TEFC) three-phase motor with a stainless steel pump construction, stainless steel semi-open impeller, Teflon/PTFE sealing components, and 1.5 inch NPT suction and discharge connections. The motor is configured for 230/460V operation with a NEMA 56J frame.
This pump is intended for applications such as chemical processing, wastewater treatment, agricultural fertilizer or fumigant transfer, and other compatible liquid-transfer duties. Its self-priming design can lift liquid up to 6 feet after the pump casing has been properly filled, while the dual-volute design is intended to help reduce radial loading. The stainless steel configuration is specified for liquids compatible with the pump's wetted materials, and fluid compatibility should be confirmed before installation.

Frequently Asked Questions
Q: What type of motor does the AMT 3893-98 use?
A: The AMT 3893-98 uses a 1.5 HP totally enclosed fan-cooled three-phase motor with a NEMA 56J frame and 230/460V electrical configuration.
Q: What size are the pump connections?
A: The pump has 1.5 inch NPT suction and 1.5 inch NPT discharge ports.
Q: What liquids can the 3893-98 pump handle?
A: It is designed for compatible nonflammable, nonabrasive liquids, including certain chemicals, wastewater, fertilizers, fumigants, acids, alkalis, caustics, solvents, and brines. Chemical compatibility with the stainless steel, seal, and other wetted materials should be verified before use.
Q: How much suction lift can this pump achieve?
A: The pump is designed to self-prime to a maximum suction lift of 6 feet after the pump casing has been properly filled.
Q: Is the AMT 3893-98 a pump and motor assembly?
A: Yes. Model 3893-98 is supplied as a complete pump and motor unit rather than only a replacement pump end. A separate pump-end assembly is available under model 3893-K8.
