DESCRIPTION

This is a single-stage centrifugal pump designed for agriculture or fire fighting service. It is close coupled to an internal combustion air cooled engine and protected

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.

Units are designed to handle clean water or water containing small (1/16” maximum spherical diameter) solids. Suction and discharge ports are 2-1/2” NPT
threaded. Discharge includes a built in bronze check valve to allow use of an exhaust or hand operated priming system.

Liquid temperature range is 40°F to 180° F (4°C to 82°C). Maximum casing pressure is 180 psi (1240 kPa). For use with nonflammable liquids that are chemically

compatible with pump component materials.
