Horizontal Split Case Pumps

Unformatted Sample Text from the Research Paper:
selected for use in coal preparation plants (Carter, 1999). Certain types are also used in fire houses. For example, Reddy-Buffaloes Horizontal Split Case pumps have been specifically manufactured for fire  pump requirements, and utilize the latest hydraulic techniques available ("Reddy-Buffaloes," 1999). Pattersons Type A pumps for example have been built and tested to move clear water, or  low viscosity clear liquids at relatively moderate heads ("New Products," 2002). They have a simple design that contributes to reduced maintenance and minimum power consumption (2003). Of course, Patterson and  Reddy-Buffaloes are just two brand names in this competitive market. There are many others . All pumps operate on similar principles. The centrifugal pump for example possesses  only one moving part, which is an impeller that is attached to a shaft and is driven by a motor ("Pump Basics," 2003). Water enters the center of the  impeller and exits the impeller with centrifugal force, and as water leaves the eye of the impeller, a low pressure area is created (2003). This causes more water to flow  into the eye, and atmospheric pressure and centrifugal force causes this occurrence (2003). Velocity is developed as the water flows through the impeller and as it is spinning at high  speed, the water velocity is collected by the diffuser and then converted to pressure by specially designed passageways that direct the water flow to the discharge area (2003). Sometimes  it will go on to the next impeller if the pump has a multi-stage configuration (2003). The pressure developed is directly linked to the number of impellers, the  size of the impeller eye, and shaft speed (2003). Capacity is further determined by the exit width of the impeller and all of these factors affect the horsepower size
