F. OPERATION
LIQUID LIMITATIONS
Never operate with fluids that are corrosive to iron, steel, aluminum or bronze. The pump is designed for fluids having the
general characteristics of oil.
CAUTION
ATTENTION
Operating conditions, such as speed, fluid viscosity, temperature, inlet pressure, discharge pressure,
filtration, duty cycle, drive type, mounting, etc. are interrelated. Due to these variable conditions, the
specific application limits may be different from that of the operational limitations. This equipment must
not be operated without verification that operating requirements are within its capabilities.
