ITT Goulds Pumps
5500 Severe Duty Slurry Pumps
The Goulds 5500 is a hard-metal centrifugal slurry pump built for the most punishing abrasive services. With extra-thick wet-end components and an extra heavy duty shaft, it is designed to keep running in duties that wear ordinary pumps out quickly, while handling large flows and high heads.
Product Benefits
- Designed against wear: Abrasive slurry attacks a pump from the inside, so the 5500 fights wear at the design level.
- Low-speed hydraulics: Its large-diameter impeller develops the required head at lower operating speeds, and slower rotation directly means slower erosion.
- Extra-thick sections: Extra-thick wall sections in the impeller and casing put extra material exactly where wear concentrates.
- Lower cost of ownership: The practical benefit is longer intervals between rebuilds and a lower total cost of ownership on severe duties.
- High Pressure option: For services that need more pressure than a single pump can deliver, a High Pressure (HP) version is available for stage or series pumping.
Where It's Used
- Pulp and paper streams: In pulp and paper mills, the 5500 is applied on heavily loaded, abrasive streams.
- Typical services: Applications include black liquor, sand slurries, mill waste, sludge, scrubber water and fly ash.
- Beyond process pumps: It suits the tough transfer duties where solids content and particle hardness rule out general-purpose process pumps.
Good to Know
- Wet-end materials: Options cover both sides of the selection problem: hard chrome irons such as HC600 and EnduraChrome for maximum abrasion resistance, and CD4MCu or 316 stainless steel where corrosion drives the choice.
- Flexible shaft sealing: Sealing can be packing, a mechanical seal or a dynamic seal (expeller), so the arrangement can match the service and the available seal water.
- Maintenance-friendly details: A positive Acme thread impeller attachment and a casing with integral rear liner and cast-in lifting lugs simplify service work.
- Heavy-duty rotor: An extra heavy duty shaft on a long bearing span with oil-lubricated double-row bearings comes as standard.
