Custom performance curves and certified test reports are issued per project against your duty point. A summary of the standard envelope follows below.\n        <\/p>\n\n        <div class=\"bbp-engineering-card\">\n          <h3 class=\"bbp-h3-title\">NPSH and Suction Performance<\/h3>\n          \n          <p class=\"bbp-card-text\">\n            A double-suction impeller halves the velocity at each impeller eye relative to an equivalent single-suction unit. This typically lowers NPSH-required by a meaningful margin at the same operating point, which is why engineers reach for split case designs whenever suction lift, hot water, or flashing-fluid risk is in play. Exact NPSH curves are duty-point specific &#8211; request the certified test report for your selection.\n          <\/p>\n          \n          <p class=\"bbp-card-text\">\n            Two stage variants are used in high-head water transfer applications with a single impeller unable to achieve the rated head economically. All standard products ship with bronze wear rings by default as the renewable wear pair against the cast iron or stainless impeller; SS316 and Duplex options are supplied with matching material wear rings.\n          <\/p>\n        <\/div>\n\n      <\/div>\n\n      <div class=\"bbp-matrix-panel\">\n        \n        <div class=\"bbp-matrix-header\">\n          <span class=\"bbp-matrix-header-col\">Parameter<\/span>\n          <span class=\"bbp-matrix-header-col\">Range \/ Specification<\/span>\n        <\/div>\n\n        <div class=\"bbp-matrix-body\">\n          \n          <div class=\"bbp-matrix-row\">\n            <div class=\"bbp-matrix-key\">Capacity (Flow)<\/div>\n            <div class=\"bbp-matrix-val\"><span class=\"bbp-highlight-val\">up to ~38,000 gpm<\/span> at full 1250 kW<\/div>\n          <\/div>\n          \n          <div class=\"bbp-matrix-row\">\n            <div class=\"bbp-matrix-key\">Head<\/div>\n            <div class=\"bbp-matrix-val\"><span class=\"bbp-highlight-val\">up to ~765 ft<\/span> single-stage;

It operates according to the same centrifugal principles as end suction and vertical inline pumps &#8211; the difference is the casing shape and impeller design.<\/p>\n                            <\/div>\n                        <\/div>\n                    <\/div>\n                <\/div>\n\n                <div class=\"bbp-faq-item\">\n                    <button class=\"bbp-faq-trigger\" aria-expanded=\"false\">\n                        <h3 class=\"bbp-h3-question\">What is the difference between single and double suction pumps?<\/h3>\n                        <div class=\"bbp-chevron\"><\/div>\n                    <\/button>\n                    <div class=\"bbp-faq-answer-wrap\">\n                        <div class=\"bbp-faq-answer-inner\">\n                            <div class=\"bbp-faq-answer-content\">\n                                <p>A single-suction impeller draws fluid in from one side, which generates an unbalanced axial thrust that must be carried by the bearings or balanced by hydraulic devices.
