NOTES: Standard continuous performance ratings listed on this KNF website and on KNF datasheets are based on technical data and test results of nominal units at sea level, measured with an ambient temperature of 70°F (21°C), and nominal electrical supply as listed above, and are for reference only.Multiple-head models, different performance models, cost-effective OEM modifications, and a variety of motor options and different materials of construction are also available. Certified drawings are available upon request. Specifications subject to change without notice. You should always check corrosion resistance charts for compatibility with the medium you intend to pump.
