End Suction Fire Fighting Water Pump IS-F125-100-315 (700gpm 130m)
Description
The ISF series Horizontal End Suction Fire Fighting Water Pumps are engineered for reliable operation upon stationary use. All fabricated parts are standardized and accurately machined for true alignment, increasing overall durability. Precision balancing of all rotating components provides mechanical dependability, reliable operation and minimal maintenance. Impellers are constructed with double inlets that practically eliminated end thrust while boosting operating efficiency.
Centrifugal pumps are the most common pumps used in firefighting applications, a single suction pump having its suction nozzle on the opposite side of the casing from the stuffing box and having the face of the suction nozzle perpendicular to the longitudinal axis of the shaft. usually of "overhung hung impeller" type in which the impeller is mounted on the end of a shaft which is “overhung” from its bearing supports.
End suction pumps are available as close coupled in which the impeller is mounted directly on the motor shaft or separately coupled in which the impeller is mounted on a separate pump shaft supported by its own bearings.
