PERFORMANCE AND OPERATING LIMITS
Flow rate and Head, if specified by the customer, are present on the plate.
The technical specifications of the pump are contained in the datasheet received in the order confirmation.
The pump can only be used for the conditions and liquids specified in the datasheet attached to the order confirmation.
If the limits are not specified, the following applies:
•
Flow rate for short periods of operation: Qmin = 10% of the flow rate at the BEP (BEP = best performance point)
•
Flow rate in continuous operation: Qmin = 30% of the BEP flow rate
•
Maximum flow rate: Qmax = 85% of the curve bottom flow rate (If a flow meter is not available refer to the head at that
point multiplied by the specific weight of the pumped liquid).
•
Tank/basin pressure = Atmospheric pressure
If the data sheet does not contain the working conditions, follow the instructions below:
•
Clean liquid
•
Non-aggressive liquid (it is the responsibility of the installer / user to check that the pump materials are suitable for the
pumped liquid and the working temperature)
•
Specific weight 1 kg/dm3
•
Viscosity 1 cPs
•
Liquid temperature MAX 50 °C
•
Atmospheric suction pressure
•
Frequency 50 HZ
For operation outside the above limits, request an update from Salvatore Robuschi & C. S.r.l. specifying the model and
serial number of the pump. Table 5 shows the maximum permissible pressure values in the pump casing (design pressure).
These values are valid for clean water at a temperature of 20°C.
CAUTION!
The design pressure is not the working pressure and can only be reached if the pump is equipped with
adequate seals.
