The United WMSND-M 3x9 8 stage horizontal multistage centrifugal pump is a high-pressure pump used in industrial applications such as boiler feed water and water transfer. The 'CA6NM' designation refers to the specific corrosion-resistant stainless steel material used for certain components. 
Key Specifications
Specific performance data for this exact configuration is dependent on operational parameters such as motor power and exact impeller diameter at the time of assembly, as these pumps are often highly customized or reconfigured. However, general specifications are available from surplus listings: 
Type: Horizontal, multi-stage centrifugal pump.
Stages: 8 stages (multiple impellers in series to build high pressure).
Material (Case): Likely carbon steel, consistent with other WMSN models.
Material (Impellers/Internals): CA6NM stainless steel, a material known for corrosion resistance, is specified for at least the impellers/internal components in similar 5-stage models.
Suction/Discharge: Pipe sizes can vary, with other 3x9 models featuring a 6" suction flange and 3" discharge flange.
Typical Performance Range: Similar 8-stage 3x9 models operate around 465 GPM @ 2120' TDH (Total Dynamic Head) at 3560 RPM. 
Applications
The multi-stage design is well-suited for applications requiring high pressure or head. Applications for this specific pump model and similar United WMSN pumps include: 
Boiler feed water.
Water transfer and pipeline systems.
Dewatering.
Saltwater disposal.
Oil & gas production and pipeline operations.
