3498 Extra Large Capacity Double Suction Pumps
The Goulds 3498 is a single-stage, double-suction pump with a horizontally split casing, built for extra-large-capacity water and cooling services. Its core strength is moving very large flows dependably in heavy-duty industrial, power-generation, and marine duty, where uptime matters more than anything else.
Product Benefits
- Balanced hydraulic forces: The double-suction impeller draws liquid in from both sides, which largely cancels axial thrust, while the dual-volute casing balances radial forces on the shaft.
- Smoother, longer running: These balanced forces mean smoother running, lighter bearing loads, and longer intervals between overhauls than a comparable single-suction design.
- Lower-half nozzles: Both the suction and discharge nozzles sit in the lower half of the casing.
- Fast rotor removal: Maintenance crews can lift out the complete rotating element without disturbing the piping or the driver, cutting downtime on a pump that is often central to mill operations.
Where It's Used
- Big mill water duties: In pulp and paper mills the 3498 covers mill water supply, headbox supply, fan pump service, showers, filtrate, cooling water, and wash water.
- Ash sluicing and fire service: It also handles ash sluicing and fire pump service.
- Round-the-clock reliability: It is a natural fit wherever a mill needs large volumes of water moved reliably around the clock.
Good to Know
- Wide metallurgy range: The pump is offered in metallurgies from cast iron with bronze-fitted trim up to stainless steel casings and impellers, so the construction can be matched to the water quality on site.
- Renewable wear rings: Hard-wearing casing wear rings protect the running clearances.
- Large flows, moderate heads: As a single-stage machine it is the right choice where the job calls for very large flows at low to moderate heads rather than extreme pressures.
- Easy inspection: The horizontally split casing makes inspection straightforward: removing the upper half exposes the entire hydraulic passage.
