Seals

{1 Comment}

Seals are necessary to prevent leakage at the point where the shaft enters the pump case. The most inexpensive seal is made of packing material that acts as a pressure breakdown device. Packing must be flexible and capable of being compressed for proper operation. Packing material may be made of flexible metallic strands with graphite …

Bearings

{0 Comments}

Ball bearings transmit a load from a rotating surface to a fixed surface via a series of rotating balls. They are generally inexpensive, do not require any separate lubrication system, and can be designed to be selfaligning. However, they have limited ability to handle thrust, high loads, or high speeds. Roller bearings transmit load from …

Centrifugal Pumps

{0 Comments}

Centrifugal pumps are classified as either radial flow or axial flow. Figure 10-1 shows a radial flow pump. Flow enters the center of the rotating wheel (impeller) and is propelled radially to the outside by centrifugal force. Within the impeller the velocity of the liquid is increased, and this is converted to pressure by the …
