DOUBLE SUCTION SINGLE STAGE PUMP

 DOUBLE SUCTION SINGLE STAGE PUMP

Note the double suction impeller. This is like having two impellers back to back, so this pump moves a high volume of liquid. 

Centrifugal pumps vary in design and construction from simple pumps with relatively few parts to extremely complicated pumps with hundreds of individual parts. Some of the most common components found in centrifugal pumps are wearing rings, stuffing boxes, packing, and lantern rings. These components are shown in Figure 10 and described on the following pages.

This double suction impeller is another method of balancing axial thrust. This allows the use of smaller thrust bearings. As this pump is in hot service, note the cooling lines are connected.
