Included: the two-stage pump with its NEMA standard motor, coupled-shaft design.
Suction and discharge piping: sized to your installation and ordered separately.
The 1500XSW is A.Y. McDonald’s two-stage multi-stage centrifugal pump, giving pressure to 60 PSI for high-pressure applications. Motors are NEMA standard construction with a coupled-shaft design, in single and three phase. Housing and adapter are cast iron.
Covered for 1 year from the date of installation, or 2 years from the date of manufacture, whichever comes first, under A.Y. McDonald’s published limited warranty terms, as set out in the A.Y. McDonald Pumps & Accessories Price List. Components made by other manufacturers, such as the motor, carry their original manufacturer’s warranty.
Each pump runs as one unit. Size it to peak demand at the pressure you need.
