End Suction Pump
Featured End Suction Centrifugal Pumps |
FILIPUSI single-stage end suction centrifugal pumps are engineered for process cooling, HVAC loops, marine ballast systems, cooling towers, and industrial booster skids. Available in three series configurations — FS (close-coupled), SW (high-efficiency), and SCW (back pull-out long-coupled) — these pumps deliver reliable performance with premium metallurgy options that eliminate downtime and mechanical seal failures in demanding service environments.
Every unit undergoes 100% hydrostatic pressure testing and dynamic shaft balancing before shipment. With flows up to 1,200 m³/h and heads up to 160 meters, FILIPUSI end suction pumps are deployed in data centers, commercial buildings, manufacturing plants, shipyards, and municipal water systems worldwide.
Applicable to: Data Center Cooling, Marine & Ballast Systems, HVAC Loops, Process Cooling, Industrial Manufacturing, Water Boosting Skids, Cooling Towers, Commercial Building Services, and Agricultural Irrigation.

Series Configurations
FILIPUSI offers three end suction pump series to match different installation, maintenance, and efficiency requirements:
|
FS Series Close-Coupled Compact direct motor-mount design eliminates shaft misalignment, reduces vibration, and saves valuable floor space. Ideal for limited-space mechanical rooms and OEM skid integration. |
SW Series High-Efficiency Optimized hydraulic design with precision-cast impellers and volutes for maximum energy efficiency. Lowers power consumption and operating cost in continuous-duty HVAC and cooling applications. |
SCW Series Back Pull-Out Long-Coupled Long-coupled design with spacer coupling allows complete rotating assembly removal for maintenance without disconnecting pipework. Preferred for large pumps and critical-process applications. |
Key Applications
|
• Data Center Cooling: Low-pulsation circulation for multi-megawatt chillers & CRAC units requiring zero thermal fluctuation and continuous uptime. |
• Cooling Towers: Reliable circulation for evaporative cooling systems in power plants, refineries, and large commercial facilities. |
|
• HVAC & Commercial Buildings: Chilled and hot water circulation for hotels, hospitals, airports, and high-rise residential complexes. |
• Marine & Ballast Systems: Bronze & Duplex stainless steel constructions prevent pitting and corrosion in high-salinity seawater service. |
|
• Industrial Manufacturing: Reliable fluid supply for induction furnace cooling, die-cast thermal regulation, and coolant filtration plants. |
• Water Boosting & Irrigation: Municipal water distribution, agricultural irrigation systems, and industrial process water supply skids. |
End Suction Pumps by Application
End Suction Pump for HVAC Chilled Water & Cooling Tower Circulation
End suction centrifugal pumps are the most widely specified pump type for HVAC chilled water and hot water circulation in commercial buildings, hospitals, airports, and data centers. The single-stage horizontal design handles the moderate heads (15-50m) and high flows (10-1,200 m³/h) typical of HVAC loops, while the back pull-out configuration on long-coupled models allows mechanical seal and bearing replacement without disconnecting pipework. For cooling tower service, 304/316 stainless steel or bronze construction resists corrosion from treated circulating water and airborne contaminants.
Close-Coupled vs. Long-Coupled End Suction Pump: How to Choose
The two most common end suction pump configurations are close-coupled (FS series), where the motor mounts directly to the pump bracket with no coupling, and long-coupled/back pull-out (SCW series), which uses a spacer coupling on a common baseplate. Choose a close-coupled pump for smaller duties (typically below 55 kW), space-constrained mechanical rooms, and lower first cost. Choose a long-coupled back pull-out pump for larger motors, critical-process applications, and installations where maintenance must be performed without disturbing the piping alignment — the rotating assembly pulls out from the rear while the casing stays bolted in place.
Stainless Steel End Suction Pump for Seawater & Corrosive Fluids
For seawater cooling, ballast transfer, chemical processing, and high-chloride water, standard cast iron end suction pumps suffer rapid pitting and seal failure. FILIPUSI supplies end suction pumps in AISI 316/316L stainless steel, Duplex 2205, and bronze metallurgy with silicon carbide mechanical seals to resist chloride corrosion and extend service life in aggressive fluids. Every corrosion-resistant pump is supplied with material test reports (MTR 3.1) for full heat-number traceability.
