In double suction pumps, if directly connected elbows can not be avoided, they should be installed such that the elbows are in a plane perpendicular to the pump shaft. Figure 1 on the following page is an illustration of a single end-suction centrifugal pump piping arrangement typi-Our Double Suction Centrifugal Pump is typically used in applications where large flow rates and high heads are required. With the pump body and impeller constructed from Stainless Steel, this pump, characterised by its unique design that allows for the simultaneous intake of liquid on both sides of the impeller, delivers a more balanced distribution of the liquid being pumped, a . Actually, in this new configuration the vanes of a conventional back-to-back double suction centrifugal pump (chosen as a baseline) are substituted by an original vanes layout, which actually sees the vanes coming from either side of the double suction impeller alternately crossing each other at the outer diameter. It should be noted that some of the newer split case pumps do have improved casing inlet designs (less inlet turbulence), which allows them to approach the higher suction energy performance (gating values) of end suction pumps. 3. Double-suction pumps are more sensitive to the orientation and geometry (radius) of elbows in front of the pump .
