Pump Performance Data* Note: Please refer to Blackmer catalog Dimension Sheets for optional jacketed head dimensions and NPT, weld neck, ANSI or DIN compatible companion flange dimensions. Note: Optional materials of construction may be required to meet specific application requirements – refer to Blackmer Material of Construction Sheets. For operating limits that exceed those listed – consult factory. * Approximate capacities and horsepower (BHP) are for the conditions specified at 50psi (3.45 BAR) differential pressure. Refer to Blackmer Characteristic Curves for capacities and horsepower at other operating conditions. www.blackmer.com World Headquarters 1809 Century Avenue SW Grand Rapids, MI 49503-1530 USA T 616.241.1611 F 616.241.3752 European Headquarters Zl la Plaine des Isles, rue des Caillottes 89000 Auxerre, FRANCE T +33.3.86.49.86.30 F +33.3.86.46.42.10 Printed in USA 09/07-2 M © 2007 Blackmer Distributed by: Pump Model NP1.5 NP2 NP2.5 SSU 31 1,000 20,000 50,000 31 1,000 20,000 50,000 31 1,000 20,000 50,000 Cp 1 210 4,200 11,000 1 210 4,200 11,000 1 210 4,200 11,000 GPM 38 45 24 10 60 70 38 16 110 122 64 28 LPM 144 170 91 38 227 265 144 61 416 462 242 106 MAX RPM 640 640 350 155 640 640 350 155 640 640 350 155 BHP 1.7 2.2 2.2 0.9 2.8 2.8 2.6 1.2 4.7 5.1 4.3 2.1 KW 1.3 1.6 1.6 0.7 2.1 2.1 1.9 0.9 3.5 3.8 3.2 1.6 Pump Model Nominal Flowrate Pump Speed Viscosity Differential Pressure Hydrostatic Pressure Temperature GPM LPM RPM SSU Cp PSI BAR PSI BAR ˚F ˚C NP1.5 47 178 640 100,000 22,000 200 13.79 300 20.68 500 260 NP2 77 291 640 100,000 22,000 200 13.79 300 20.68 500 260 NP2.5 136 515 640 100,000 22,000 200 13.79 300 20.68 500 260 NP3 276 1,045 640 100,000 22,000 200 13.79 300 20.68 500 260 NP4 525 1,985 500 100,000 22,000 200 13.79 300 20.68 500 260 Pump Model A B D E G K N Q S T V Approx.
