F. OPERATION
F.1 LIQUID LIMITATIONS
Never operate with thin liquids such as solvents or water. Pump is designed for liquids having
general characteristics of oil.
F.2 OPERATING LIMITS
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, specific application limits may be
different from operational limitations. Equipment must not be operated without
verifying system operating requirements are within pump’s capabilities.
Under no circumstances are the following structural limitations to be exceeded.
