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 that of operational
limitations. Equipment must not be operated without verifying system’s operating
requirements are within pump’s capabilities.
Under no circumstances are following operating limits (specified in Table 1) to be exceeded
without specific approval from Imo Pump.
