Single-stage, Centrifugal, 316L Stainless Steel Top-Mounted Pump

Pump & Motor Assemblies

A centrifugal, 316L stainless steel-fitted, vertical design with stainless steel liquid handling components. Pump is fitted with propeller shaft for applications where the return piping is at or below floor level. A patented design (U.S. Patent #4,932,846) is typically more durable and simpler than most other design which often have chronic lower bearing failure. Column depths can range from 6 inches to 23 inches (similar to Model MU). Pump types (such as 113-U, 114-U, etc.) selected depends on the design operating conditions—flow rate, discharge pressure and NPSH requirements; impellers trimmed to operating conditions.

Equipped with industry standard motors available in single or three-phase at 3500 RPM only. Pumps are furnished with seal flush port to help prevent the pump from vapor binding and to allow pump operation against a dead shut-off for a period of time without burning seals. Standard mechanical seals provide for temperatures up to 250°F. Higher temperature seals and special faces available upon request.
