The EnergyPlus.idd file does not specify an input range for the pump coefficients:
N7 , \field Coefficient 1 of the Part Load Performance Curve
\default 0.0
N8 , \field Coefficient 2 of the Part Load Performance Curve
\default 1.0
N9, \field Coefficient 3 of the Part Load Performance Curve
\default 0.0
N10, \field Coefficient 4 of the Part Load Performance Curve
\default 0.0
However, the simulation will throw an error if pump power is negative, so you should probably stay away from negative coefficient values. You can see where the program is using the coefficients in the pump power calculation, there may be some other implicit limits based on what's physically realistic for pump operation.
