Grundfos TP User Manual

9.1.4 Inlet pressure
To ensure optimum and quiet pump operation, the
inlet pressure (system pressure) must be adjusted
correctly.
For the calculation of specific inlet pressures, contact
the local Grundfos company or see the data booklet
for TP, TPD, TPE, TPED, TPE2, TPE2 D, TPE3,
TPE3 D, if at hand.
The total pressure of the inlet pressure and the pump
pressure must be lower than the maximum operating
pressure stated on the pump nameplate.
The pumps comply with IEC 60335-2-51 if the
maximum inlet pressure is equal to or less than half
of the maximum operating pressure stated on the
pump nameplate.
9.1.5 Maximum flow rate
Do not exceed the maximum flow rate as
otherwise there is a risk of, for instance,
cavitation and overload.
The minimum and maximum flow rates and total
heads can be read either from the performance curve
pages in the relevant data booklets or from a curve
for a specific pump when selecting it in Grundfos
Product Center. See www.grundfos.com.
9.2 Enclosure class
Closed drain hole in motor: IP55
