American Models PSD/PSDB/CSD/CSDB/FSD 125
1250 GPM at 150 PSI
Single Stage Pump -10-inch Impeller
Use this chart to select the proper engine to pump ratio. The approximate pump input speed and horsepower requirements shown are for the
underwriter rating*.
Maximum lift at which the pump will do the rating at sea level: ****
With 20 feet of 6-inch suction hose is 16 feet
Maximum elevation at which the pump will do the rating on 10-foot lift: ****
With 20 feet of 6-inch suction hose is 4900 feet.

* Engine speed must not exceed manufacturer's maximum no-load governed speed.
** Gauge pressure does not include lift or suction losses.
*** The pump is capable of the high pressure performance shown; actual obtainable pressure should be checked in advance, and is governed by maximum
engine speed, available horsepower and pump ratio.
**** Maximum lift/elevation listed with direct suction hose pump hookup.
Gross engine power curves represent power without accessories. To obtain net power for pumping, deduct for accessory power losses, and deduct for
elevations above sea level per engine manufacturer's recommendations.
When pump is driven via the front engine crankshaft PTO or transmission PTO, the PTO rating should equal or exceed
pump power requirements.
