DESCRIPTION

This is a single-stage centrifugal pump designed for agriculture or re ghting service. It is close coupled to an internal combustion air cooled engine and pro-

tected by a roll frame equipped with four carry handles. The pump is compact and light-weight, designed for portability. Pump construction is rugged and allows

for easy maintenance.
