PDF datasheet mirror for Between bearings double suction pumps SZM, SZMV (Sulzer Pumps). Verify with OEM before design.
Summary
Product identification
Sulzer Pumps SZM and SZMV Between Bearings Double Suction Centrifugal Pumps.
Main Applications
These pump series provide reliability during continuous operation and handle clean or slightly polluted fluids in various industrial applications, including:
- Water Treatment
- Desalination
- Water Transport & Supply
- Irrigation
- Power Plants (cooling water auxiliary services)
- HPI (general water cooling services)
- General Industry
Features and Benefits
- Double suction impeller: Balances axial thrust and improves suction capability.
- Axial split casing design: Features inline suction and discharge nozzles in the bottom casing, allowing easy maintenance by removing the upper casing without disassembling nozzles.
- Casing wear rings with optional impeller wear rings: Ensure proper maintenance and longer pump lifecycle.
- Heavy duty, grease or oil lubricated bearings:
- Ball bearings at both Drive End (DE) and Non-Drive End (NDE) for smaller sizes.
- Roller bearing at DE and double angular contact bearing at DE for larger sizes.
- Combines modularity with heavy duty design for reliable operation.
- Double volute: Available for larger sizes to reduce radial thrust.
- Vertical arrangement (SZMV): Enables adaptability to customer layout requirements.
