Description
The AS-1160 Split Casing Pump is a heavy-duty centrifugal pump concept designed for high-flow, continuous-duty liquid transfer where efficiency, service accessibility, and mechanical stability are critical. The horizontally split casing arrangement allows the upper casing half to be removed for internal inspection and maintenance without disturbing major pipework, while double-suction hydraulic geometry is commonly used in split-case designs to reduce axial thrust and improve bearing and seal life. Split-case pump manufacturers commonly position this design for water supply, HVAC, district cooling, irrigation, and industrial utility duties.
For target applications, the AS-1160 should be positioned for municipal water distribution, chilled/condenser water circulation, fire-fighting systems, irrigation pumping stations, power-plant service water, petrochemical utility water, cooling-water recirculation, and general industrial transfer. Split-case pumps are used for public water supply, air-conditioning/heating systems, district heating/cooling, irrigation, fire-fighting, power stations, shipbuilding, petrochemical service, and clean/service-water handling.
Technical Key Features
- Rigid bearing support arrangement for stable shaft operation under sustained industrial duty.
- Double-suction impeller configuration reduces axial hydraulic load and supports smoother operation.
- Renewable wear components, such as wear rings and shaft sleeves, support long-term maintainability.
- Service-friendly construction enables internal access without full pump removal from the piping system.
- High-flow centrifugal hydraulic layout suitable for continuous water transfer and utility circulation duties.
- Horizontally split casing design for rapid inspection of impeller, wear rings, shaft sleeves, and sealing area.
- Multiple sealing options, including gland packing, component mechanical seal, or cartridge mechanical seal.
