This type of centrifugal pump uses a casing design that draws in fluid from the end of the pump and discharges fluid out the top. End suction pumps are almost always single stage pumps, which means they use only one impeller.
End suction pumps are the most common configuration for centrifugal pumps, and the least expensive configuration in many cases. A huge variation of sizes, materials of construction, and designs are offered by manufacturers to handle everything from water at ambient temperature to high pressure and high temperature viscous oils, abrasive slurries, and corrosive chemicals.
Key Advantages
- Moderate floor space requirement
- Flexibility in mechanical room layout
- Available in electric or diesel drive
- Easily serviceable
Disadvantages / Shortcomings
- Comparatively lower range of performance - up to 1500 US GPM
- Single suction design
- Limited hydraulic efficiency
- Single suction design limits hydraulic efficiency
Applications
End suction pumps are often used for lower flow and lower pressure installations. In fire suppression applications, End-Suction pumps are often diesel-driven.
Design Advantages in Armstrong End-Suction Fire Pumps
Armstrong Horizontal End-Suction (HES) fire pumps deploy a heavy-duty bearing frame to provide long and reliable service in an over-hung impeller design. The end-suction format also eliminates the design layout constraints imposed by horizontal split-case pump configurations
Factory-based pump-motor alignment for easy installation
Back pull-out design for easy replacement of wear ring (no disruption of casing or piping)
Advanced mechanical features including flexible pump-motor coupling (OSHA guard), self-venting centre line casing, and seal recirculation lines provide extended durability and easy maintenance.
