Double-row, outboard thrust bearings and oil lubrication are optional. How the design of horizontal split-case pumps makes the difference. Coupled with robust bearings and a maintenance-friendly casing design, split-case pumps are the design-of-choice for many municipalities and industrial facilities. Double suction, between bearing, split case pumps (see figure 3) are the second most popular centrifugal pump configuration, second only to the more common end suction, radial split design. Check out Part 6 where we talk about pump seals!
This reduces the tendency of unequal flow quantities reaching the two impeller eyes. Inlet and outlet diameters are 150-600mm, with its flanges press GB/T17241. Double Suction Impeller Assures Hydraulic Axial Balance for lower thrust bearing loads, longer pump life, and lower maintenence. We typically recommend a double suction pump design for HVAC applications around 2, 000 GPM or an 8" pump size. Temperature: 105℃max. Design Features: - Horizontally Split Casing In-line suction and discharge nozzles in lower half casing for ease of inspection/maintenance. Horizontal, between bearings, single stage, axially split centrifugal pump. Features & Benefits. For additional information: Manufacturer's Website. If required, the SDS split casing centrifugal pump can be supplied with an external air powered or electric priming pump for applications where a suction lift is unavoidable.

In addition, features like in-between-bearing designs enable these pumps to keep on working for more extended periods without needing frequent maintenance. Parts fabrication (as required). Product Features Expect more with the improved design and above standard, standard materials options of the e-XC split-case pump: •Xylem's proprietary mechanical seals - carbon/silicon... Flow: 31, 800 m³/h. Double suction, enclosed impellers provide hydraulic balance eliminating axial thrust. Head: 600'00"... Series 8100, 8300 and 9100 pump, Xylem's e-XC split case pump offers a broader hydraulic range with flows that exceed 57, 000 gpm and head over 800 feet. Their average life is 100, 000 hours.
Materials of Pump: Bronze, Cast Iron, Carbon Steels. Thus, they can be widely used. When higher capacities are required, double-suction pumps can be a long-lasting solution.
