Description
The AMT 4900-97 is a 3 HP pumps centrifugal pump. Delivers up to 42 GPM. AMT High Head End Suction Centrifugal pumps are designed for continuous-duty OEM, Industrial/Commercial and processing applications including circulation, chemical processing, liquid transfer, and pressure boosting. All models feature stainless steel
End-Suction Close-Coupled Design
Close-coupled design eliminates the flexible coupling and separate bearing housing of frame-mounted pumps — fewer components, smaller footprint, and lower maintenance requirements. NEMA-frame motor for direct interchangeability with standard replacements.
Dual Volute Casing — Extended Bearing and Seal Life
Dual volute design balances radial hydraulic forces on the impeller. Single-volute pumps develop a net radial force that increases bearing wear especially at off-BEP points. The dual volute significantly extends bearing and mechanical seal service life.
Multiple Construction Options
Available in cast iron, bronze, stainless steel, and thermoplastic construction — select the casing and seal materials matched to your specific fluid, temperature, and chemical compatibility requirements.
NEMA 56J Frame — Standard Motor Interchangeability
NEMA 56J motor frame is fully interchangeable with motors from any major manufacturer. Motor replacement in the field requires no special tooling, no custom parts, and no factory service — any electrician can replace the motor with a standard stocking item.
QSP Quick Ship Program
Standard configurations ship within 24 hours from AMT's Quick Ship Program. For applications where pump downtime has direct operational impact, QSP availability eliminates extended lead time on the most common configurations.
Continuous Duty Rating
TEFC motors are rated for continuous duty operation — not a duty-cycle rated motor. Designed for 24/7 operation in industrial environments without derating or forced cooling intervals.
