How does a double suction pump operate?

Explanation:
Double suction pumps feed water into the impeller from two opposite sides. This means the fluid enters from both suction openings, meets at the impeller eye, and is then accelerated outward by the impeller into the casing. That dual inlet allows a larger impeller diameter and higher flow while balancing hydraulic forces, which reduces axial thrust on the bearings. It’s not about entering from the top, nor about two separate impellers.
