The Frame S Centrifugal Pump is the heavy duty alternative to standard small frame pumps which can easily become overstressed when operated off the best efficiency point of its performance curve. The Frame S Centrifugal Pump provides mid-frame strength and reliability in small frame space. It can be installed in the same space, on the same baseplate, and with the same piping as conventional small frame pumps, and is available in four different sizes.
- Heavy duty alternative to standard small frame pumps
- Lowest L³/D4 stiffness ratio of any competitive size pump
- Designed and built for the toughest applications
Features and Benefits
- Mid-size frame strength and reliability in small frame space - heavy-duty alternative to standard small frame pumps
- Four model sizes to fit a wide range of applications and size restrictions
- Lowest L3/D4 stiffness ratio of any competitive size pump - 46 (1.9) Frame S
- Meets ASME/ANSI dimensional specifications
- Flow capacities to 450 gpm (102 m3/hr)
- Equipped to accept a C-Frame (NEMA)/D-Flange (IEC) motor adaptor, providing
alignment of motor and power end without special tools or excessive labor - Right or left side discharge is possible with optional special foot

Performance Assurance
Five Year Power End Performance Assurance
Should any Blackmer Centrifugal Power End component fail within 5 years of the original installation, including bearings or shafts that have fractured, a free replacement component will be provided. This offer is limited to a claim for one of each component per power end.*
One Year Mechanical Seal Performance Assurance
Should any factory supplied and installed mechanical seal fail within one year after the sale of the pump and seal, a spare parts kit (with materials the same as the original seal) will be provided at no charge. Limit of one seal claim per application.*
