I’ve uploaded the pump curve from the manufacturer’s site for the particular model pump in question. From the nameplate on the pump, I have the following related information:
H = 137.5 ft
H_max = 193.2 ft
Q = 30.38 US gpm
2 HP motor
I expected the pump curve and nameplate information would be very close, but from the pump curve I should expect closer to 150 ft of head for a flow of 30 gpm. Are there some common reasons for this mismatch, such as particular unit changes that would only be reflected in the documents issued with purchase?
Edit: the pump is used to keep a building water loop in constant recirculation - the water is at ambient temperature
