End suction pumps are one of the most common classes of centrifugal pumps, with a simple design providing tried-and-true reliable pumping solutions for centuries. The most common type of end suction pump is single stage and operates on the basic principle of fluid flowing into the inlet of the pump and into the eye of the impeller. The rotating impeller creates centrifugal force, pumping the fluid around the volute casing where the high velocity is converted into high pressure through a diffusion process.
End Suction Pump Configurations
End suction single-stage pumps are available in a range of sizes, construction materials, and design for various applications. End suction centrifugal pumps are typically driven by an AC electric motor, although DC motor pumps are available. Other variations include diesel engines, hydraulic motors, gasoline engines, and steam turbines. Two basic configurations include a frame-mounted pump or a close coupled system, although PACO end suction centrifugal pumps come in close coupled, split coupled, and frame mounted options.
Paco end suction pumps feature a double volute design to reduce radial loads, internal turbulence, and recirculation for a longer-lasting seal and bearing life. A Shaft Sleeve protects the shaft against corrosion and wear, reducing maintenance costs and extending pump life. The Suction Splitter reduces pre-rotation and turbulence, extending pump life and reducing operating costs. End suction pumps are available in various materials of construction, often in cast iron.
End Suction Centrifugal Pump Applications
End suction pumps are utilized in many industrial, commercial, and residential applications such as water supply, industrial applications for liquid transfer and pressure boosting, agricultural, heating, ventilation and air conditioning, irrigation processes, and more. Centrifugal pumps do a good job in many fluid transfer applications, whether involving water, corrosive chemicals, abrasive slurries, or high-temperature viscous oils.
Standard end suction pumps used in water applications are typically close-coupled and constructed of plastic or standard iron. Stainless steel and exotic alloys provide corrosion resistance, hardened cast-iron options are ideal for slurry applications such as mining, minerals processing, and dredging.
End suction pumps are often utilized in many food processing or chemical applications. A close coupled pump shaft can be sealed from the environment providing efficient pumping and safety.
