ITT Goulds Pumps
SRL Severe Duty Slurry Pumps
The Goulds Model SRL is the original rubber-lined slurry pump, developed for the most severe and abrasive slurry duties. Field-replaceable rubber liners and a robust, oil-lubricated cartridge bearing assembly give it a reputation for reliability and long life on punishing services.
Product Benefits
- Resilient rubber lining: Rubber lining answers abrasion differently from hard metal: the resilient liner absorbs particle impact rather than resisting it, which works especially well on fine, sharp solids.
- Field-replaceable liners: Because the liners are molded and bonded to a metal skeleton and are field-replaceable, worn wet-end surfaces are renewed without replacing the whole casing.
- Heavy-duty rotating assembly: An oil-lubricated cartridge bearing assembly engineered for very long bearing life pairs with a large-diameter steel shaft and a hard-coated shaft sleeve over a stainless base.
- Planned, not unplanned: Together these features keep the pump running between planned liner changes rather than failing between them.
Where It's Used
- Abrasive mill services: In pulp and paper plants, the SRL is applied on abrasive services such as lime slurries and fly ash.
- Continuously abrasive streams: It is the kind of pump chosen for streams that stay abrasive around the clock.
- Scheduled liner renewal: Liner renewal is planned into the maintenance calendar as routine work.
Good to Know
- A family of variants: The standard SRL uses a large-diameter open impeller, the SRL-C a closed impeller for somewhat coarser solids, the SRL-XT adds extra-thick rubber for extended wear life, and the SRL-S fits a Shearpeller for froth-laden and stringy slurries.
- Liner technology options: Larger sizes use an FRP composite hybrid liner, and a Ceramic-Rubber Media (CRM) option is available where rubber alone is not enough.
- Sealing flexibility: Shaft sealing can use standard or low-dilution seal water arrangements or a mechanical seal, so the pump can be configured around how much dilution the process tolerates.
- Know the limits: Rubber-lined pumps suit fine abrasive solids; very coarse or tramp material is better matched to hard-metal designs.
