10/07/  · We typically recommend a double suction pump design for HVAC applications around 2,000 GPM or an 8” pump size. When it comes to applying a double suction pump we suggest: (1) Selecting a pump with the shortest shaft span possible to minimize shaft deflections. (2) Specifying based-mounted pumps with flexible couplers whenever possible.

In thisarticle, the centrifugal pump experimental system includes double-suction 

Double-suction pumps are more sensitive to the orientation and geometry (radius) of elbows in front of the pump inlet (see April column). Suction elbows should be perpendicular to the plan view of the shaft. This reduces the tendency of unequal flow quantities reaching the two impeller eyes.

Figure 1 is a simplified diagram of a typical centrifugal pump that shows the relative locations of the pump suction, impeller, volute, and discharge. The pump casing guides the liquid from the suction connection to the center, or eye, of the impeller. The vanes of the rotating , impeller,

17/08/  · Suction cavitation in centrifugal pumps (Reference: thermal-engineering.org)The Structure of Centrifugal Pumps A centrifugal pump consists of a set of components that some (e.g., shaft, bearing, etc.) are responsible for maintaining the mechanical structure of the pump, and others (impellers and casing) determine the hydraulic function of the pump.

Double Suction Pump. JYSN split case double suction centrifugal pump is used to transport clean water without physical particles or other liquids with similar physical and chemical properties to water, the medium temperature does not exceed 80℃, the series split case pumps are suitable for factories, mines, urban water supply and drainage, power stations, farmland irrigation and

In single-suction centrifugal pumps, the water enters on one side of the casing and impeller. Double-suction centrifugal pump is usually used in water service.

investigated pump is a large double-suction centri- fugal pump. Figure 1 shows the picture of the pump during experimental measurement. The pump has two twin impellers built together, as shown
