PERFORMANCE CURVE CHARACTERISTICS

• Impellers are trimmed to the nearest 1/16" increment to supply required capacity. Responsibility for final impeller sizing remains with Xylem Bell & Gossett.

• Maximum Suction Pressure for pumps is 35 psi. Maximum Water Temperature is 250 °F.

• Horsepower curves do not include motor service factor. Typical motor service factors are as follows:

ODP Enclosure – 1.15 Minimum (up to 1.75 are used when available.) TEFC Enclosure – 1.15 Minimum (up to 1.75 are used when available.) Exp. Proof Enc. – 1.0

• NPSH Required is provided for cold (120°F and below) and hot water (above 120°F) applications. NPSH Required is determined by utilizing a vacuum pump to equalize atmospheric pressure and vapor pressure and then mea- suring the required static head of water for non-cavitating pump operation.

• Pumps available from stock are indicated on the respective performance curve by their part number.

• Pumps supplied for 45 GPM or less may include external orificing to facilitate matching of design conditions and to limit maximum motor loads. The orifice extends the pump discharge by 3 1/2". Pumps for 15 GPM or less will be orificed and the orifice will have a 3/4 NPT discharge. Orificing is at the discretion of B&G.
