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 operating limits (specified in table 1) to be exceeded
without specific approval from Imo Pump.
